the causes and effects of pollution essay

Causes and Effects of Pollution

The environment people live in is affecting them, including health and lifestyle, and the nature around them, like plants, animals, water bodies, and the atmosphere. Environmental issues caused by humans using natural resources and treating nature with no respect have resulted in some negative changes. One of the most significant problems people are facing nowadays is pollution. It affects all the crucial elements for sustaining human life: water, air, and soil. The causes and effects of pollution are multiple and varied, and they should be examined closely to better understand this phenomenon.

General reasons for pollution include major emissions of carbon dioxide, as well as the chemicals produced as the result of the burning of fossil fuels. This happens because of different factories’ activity and their waste, which is being discharged into water, soil, and the atmosphere. Other than big manufacturing elements, pollution is caused by people individually. This involves emissions caused by cars, using much energy for different activities, and producing enormous amounts of waste, especially the types that are not decomposable or take hundreds of years to do so.

The first side of the environment impacted by pollution is the atmosphere. Air pollution can be defined as a combination of harmful gases or particles that accumulate in the air in unsafe quantities. The worsening air quality can result in multiple health issues, including “heart disease, lung cancer, and both chronic and acute respiratory diseases” (“Ambient (outdoor) air pollution,” 2018, para. 1). As air quality is measured around the world, many deficiencies are detected, which directly influence human life.

According to the World Health Organization data, in 2016, about 91 percent of the population inhabited places with unsatisfactory air quality (as cited in “Ambient (outdoor) air pollution,” 2018). Therefore, air pollution is affecting not only those living in big urban areas but is also spreading around the whole planet.

Water covers the majority of the planet, so water pollution is also a crucial problem. Wastewater and emission of fertilizers into water bodies cause water pollution, which can make water harmful to human consumption. Other than becoming undrinkable, contaminated water will affect or even kill aquatic creatures and plants, as well as transfer to crops, making them just as dangerous. The United Nations World Water Development Report stated that over 80 percent of wastewater is discharged back into the environment, not being appropriately treated (2017). Thus, not only do the major water bodies become largely polluted but the effect is also transferred to soil.

As a significant part of the food for humans and domestic animals is grown, polluted soil can also cause complications. Soil pollution occurs when certain toxic chemicals are gathered in large amounts. Soil can be affected by harmful substances as a result of industrial waste emission into the ground, contaminated water interacting with it, or excessive amounts of pesticides or fertilizers being used. As a result, plants and crops become dangerous for human consumption and can cause multiple health problems.

Pollution is a global phenomenon, causing much damage to the planet and harming people and other living creatures. It can manifest in different forms, but its impact is hugely detrimental. Seeking solutions for this problem is now one of the main agendas for the whole of humankind, which can only be done with combined efforts of government structures and community and individual actions. Only by being aware of this situation and taking measures for improvement will people be able to protect their health and create better conditions for future generations.

Pollution is the introduction of harmful materials into the environment . These harmful materials are called pollutants . Pollutants can be natural, such as volcanic ash . They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land. Many things that are useful to people produce pollution. Cars spew pollutants from their exhaust pipes. Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides —chemical poisons used to kill weeds and insects— seep into waterways and harm wildlife . All living things—from one-celled microbes to blue whales—depend on Earth ’s supply of air and water. When these resources are polluted, all forms of life are threatened. Pollution is a global problem. Although urban areas are usually more polluted than the countryside, pollution can spread to remote places where no people live. For example, pesticides and other chemicals have been found in the Antarctic ice sheet . In the middle of the northern Pacific Ocean, a huge collection of microscopic plastic particles forms what is known as the Great Pacific Garbage Patch . Air and water currents carry pollution. Ocean currents and migrating fish carry marine pollutants far and wide. Winds can pick up radioactive material accidentally released from a nuclear reactor and scatter it around the world. Smoke from a factory in one country drifts into another country. In the past, visitors to Big Bend National Park in the U.S. state of Texas could see 290 kilometers (180 miles) across the vast landscape . Now, coal-burning power plants in Texas and the neighboring state of Chihuahua, Mexico have spewed so much pollution into the air that visitors to Big Bend can sometimes see only 50 kilometers (30 miles). The three major types of pollution are air pollution , water pollution , and land pollution . Air Pollution Sometimes, air pollution is visible . A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible . Polluted air can be dangerous, even if the pollutants are invisible. It can make people’s eyes burn and make them have difficulty breathing. It can also increase the risk of lung cancer . Sometimes, air pollution kills quickly. In 1984, an accident at a pesticide plant in Bhopal, India, released a deadly gas into the air. At least 8,000 people died within days. Hundreds of thou sands more were permanently injured. Natural disasters can also cause air pollution to increase quickly. When volcanoes erupt , they eject volcanic ash and gases into the atmosphere . Volcanic ash can discolor the sky for months. After the eruption of the Indonesian volcano of Krakatoa in 1883, ash darkened the sky around the world. The dimmer sky caused fewer crops to be harvested as far away as Europe and North America. For years, meteorologists tracked what was known as the “equatorial smoke stream .” In fact, this smoke stream was a jet stream , a wind high in Earth’s atmosphere that Krakatoa’s air pollution made visible. Volcanic gases , such as sulfur dioxide , can kill nearby residents and make the soil infertile for years. Mount Vesuvius, a volcano in Italy, famously erupted in 79, killing hundreds of residents of the nearby towns of Pompeii and Herculaneum. Most victims of Vesuvius were not killed by lava or landslides caused by the eruption. They were choked, or asphyxiated , by deadly volcanic gases. In 1986, a toxic cloud developed over Lake Nyos, Cameroon. Lake Nyos sits in the crater of a volcano. Though the volcano did not erupt, it did eject volcanic gases into the lake. The heated gases passed through the water of the lake and collected as a cloud that descended the slopes of the volcano and into nearby valleys . As the toxic cloud moved across the landscape, it killed birds and other organisms in their natural habitat . This air pollution also killed thousands of cattle and as many as 1,700 people. Most air pollution is not natural, however. It comes from burning fossil fuels —coal, oil , and natural gas . When gasoline is burned to power cars and trucks, it produces carbon monoxide , a colorless, odorless gas. The gas is harmful in high concentrations , or amounts. City traffic produces highly concentrated carbon monoxide. Cars and factories produce other common pollutants, including nitrogen oxide , sulfur dioxide, and hydrocarbons . These chemicals react with sunlight to produce smog , a thick fog or haze of air pollution. The smog is so thick in Linfen, China, that people can seldom see the sun. Smog can be brown or grayish blue, depending on which pollutants are in it. Smog makes breathing difficult, especially for children and older adults. Some cities that suffer from extreme smog issue air pollution warnings. The government of Hong Kong, for example, will warn people not to go outside or engage in strenuous physical activity (such as running or swimming) when smog is very thick.

When air pollutants such as nitrogen oxide and sulfur dioxide mix with moisture, they change into acids . They then fall back to earth as acid rain . Wind often carries acid rain far from the pollution source. Pollutants produced by factories and power plants in Spain can fall as acid rain in Norway. Acid rain can kill all the trees in a forest . It can also devastate lakes, streams, and other waterways. When lakes become acidic, fish can’t survive . In Sweden, acid rain created thousands of “ dead lakes ,” where fish no longer live. Acid rain also wears away marble and other kinds of stone . It has erased the words on gravestones and damaged many historic buildings and monuments . The Taj Mahal , in Agra, India, was once gleaming white. Years of exposure to acid rain has left it pale. Governments have tried to prevent acid rain by limiting the amount of pollutants released into the air. In Europe and North America, they have had some success, but acid rain remains a major problem in the developing world , especially Asia. Greenhouse gases are another source of air pollution. Greenhouse gases such as carbon dioxide and methane occur naturally in the atmosphere. In fact, they are necessary for life on Earth. They absorb sunlight reflected from Earth, preventing it from escaping into space. By trapping heat in the atmosphere, they keep Earth warm enough for people to live. This is called the greenhouse effect . But human activities such as burning fossil fuels and destroying forests have increased the amount of greenhouse gases in the atmosphere. This has increased the greenhouse effect, and average temperatures across the globe are rising. The decade that began in the year 2000 was the warmest on record. This increase in worldwide average temperatures, caused in part by human activity, is called global warming . Global warming is causing ice sheets and glaciers to melt. The melting ice is causing sea levels to rise at a rate of two millimeters (0.09 inches) per year. The rising seas will eventually flood low-lying coastal regions . Entire nations, such as the islands of Maldives, are threatened by this climate change . Global warming also contributes to the phenomenon of ocean acidification . Ocean acidification is the process of ocean waters absorbing more carbon dioxide from the atmosphere. Fewer organisms can survive in warmer, less salty waters. The ocean food web is threatened as plants and animals such as coral fail to adapt to more acidic oceans. Scientists have predicted that global warming will cause an increase in severe storms . It will also cause more droughts in some regions and more flooding in others. The change in average temperatures is already shrinking some habitats, the regions where plants and animals naturally live. Polar bears hunt seals from sea ice in the Arctic. The melting ice is forcing polar bears to travel farther to find food , and their numbers are shrinking. People and governments can respond quickly and effectively to reduce air pollution. Chemicals called chlorofluorocarbons (CFCs) are a dangerous form of air pollution that governments worked to reduce in the 1980s and 1990s. CFCs are found in gases that cool refrigerators, in foam products, and in aerosol cans . CFCs damage the ozone layer , a region in Earth’s upper atmosphere. The ozone layer protects Earth by absorbing much of the sun’s harmful ultraviolet radiation . When people are exposed to more ultraviolet radiation, they are more likely to develop skin cancer, eye diseases, and other illnesses. In the 1980s, scientists noticed that the ozone layer over Antarctica was thinning. This is often called the “ ozone hole .” No one lives permanently in Antarctica. But Australia, the home of more than 22 million people, lies at the edge of the hole. In the 1990s, the Australian government began an effort to warn people of the dangers of too much sun. Many countries, including the United States, now severely limit the production of CFCs. Water Pollution Some polluted water looks muddy, smells bad, and has garbage floating in it. Some polluted water looks clean, but is filled with harmful chemicals you can’t see or smell. Polluted water is unsafe for drinking and swimming. Some people who drink polluted water are exposed to hazardous chemicals that may make them sick years later. Others consume bacteria and other tiny aquatic organisms that cause disease. The United Nations estimates that 4,000 children die every day from drinking dirty water. Sometimes, polluted water harms people indirectly. They get sick because the fish that live in polluted water are unsafe to eat. They have too many pollutants in their flesh. There are some natural sources of water pollution. Oil and natural gas, for example, can leak into oceans and lakes from natural underground sources. These sites are called petroleum seeps . The world’s largest petroleum seep is the Coal Oil Point Seep, off the coast of the U.S. state of California. The Coal Oil Point Seep releases so much oil that tar balls wash up on nearby beaches . Tar balls are small, sticky pieces of pollution that eventually decompose in the ocean.

Human activity also contributes to water pollution. Chemicals and oils from factories are sometimes dumped or seep into waterways. These chemicals are called runoff. Chemicals in runoff can create a toxic environment for aquatic life. Runoff can also help create a fertile environment for cyanobacteria , also called blue-green algae . Cyanobacteria reproduce rapidly, creating a harmful algal bloom (HAB) . Harmful algal blooms prevent organisms such as plants and fish from living in the ocean. They are associated with “ dead zones ” in the world’s lakes and rivers, places where little life exists below surface water. Mining and drilling can also contribute to water pollution. Acid mine drainage (AMD) is a major contributor to pollution of rivers and streams near coal mines . Acid helps miners remove coal from the surrounding rocks . The acid is washed into streams and rivers, where it reacts with rocks and sand. It releases chemical sulfur from the rocks and sand, creating a river rich in sulfuric acid . Sulfuric acid is toxic to plants, fish, and other aquatic organisms. Sulfuric acid is also toxic to people, making rivers polluted by AMD dangerous sources of water for drinking and hygiene . Oil spills are another source of water pollution. In April 2010, the Deepwater Horizon oil rig exploded in the Gulf of Mexico, causing oil to gush from the ocean floor. In the following months, hundreds of millions of gallons of oil spewed into the gulf waters. The spill produced large plumes of oil under the sea and an oil slick on the surface as large as 24,000 square kilometers (9,100 square miles). The oil slick coated wetlands in the U.S. states of Louisiana and Mississippi, killing marsh plants and aquatic organisms such as crabs and fish. Birds, such as pelicans , became coated in oil and were unable to fly or access food. More than two million animals died as a result of the Deepwater Horizon oil spill. Buried chemical waste can also pollute water supplies. For many years, people disposed of chemical wastes carelessly, not realizing its dangers. In the 1970s, people living in the Love Canal area in Niagara Falls, New York, suffered from extremely high rates of cancer and birth defects . It was discovered that a chemical waste dump had poisoned the area’s water. In 1978, 800 families living in Love Canal had to a bandon their homes. If not disposed of properly, radioactive waste from nuclear power plants can escape into the environment. Radioactive waste can harm living things and pollute the water. Sewage that has not been properly treated is a common source of water pollution. Many cities around the world have poor sewage systems and sewage treatment plants. Delhi, the capital of India, is home to more than 21 million people. More than half the sewage and other waste produced in the city are dumped into the Yamuna River. This pollution makes the river dangerous to use as a source of water for drinking or hygiene. It also reduces the river’s fishery , resulting in less food for the local community. A major source of water pollution is fertilizer used in agriculture . Fertilizer is material added to soil to make plants grow larger and faster. Fertilizers usually contain large amounts of the elements nitrogen and phosphorus , which help plants grow. Rainwater washes fertilizer into streams and lakes. There, the nitrogen and phosphorus cause cyanobacteria to form harmful algal blooms. Rain washes other pollutants into streams and lakes. It picks up animal waste from cattle ranches. Cars drip oil onto the street, and rain carries it into storm drains , which lead to waterways such as rivers and seas. Rain sometimes washes chemical pesticides off of plants and into streams. Pesticides can also seep into groundwater , the water beneath the surface of the Earth. Heat can pollute water. Power plants, for example, produce a huge amount of heat. Power plants are often located on rivers so they can use the water as a coolant . Cool water circulates through the plant, absorbing heat. The heated water is then returned to the river. Aquatic creatures are sensitive to changes in temperature. Some fish, for example, can only live in cold water. Warmer river temperatures prevent fish eggs from hatching. Warmer river water also contributes to harmful algal blooms. Another type of water pollution is simple garbage. The Citarum River in Indonesia, for example, has so much garbage floating in it that you cannot see the water. Floating trash makes the river difficult to fish in. Aquatic animals such as fish and turtles mistake trash, such as plastic bags, for food. Plastic bags and twine can kill many ocean creatures. Chemical pollutants in trash can also pollute the water, making it toxic for fish and people who use the river as a source of drinking water. The fish that are caught in a polluted river often have high levels of chemical toxins in their flesh. People absorb these toxins as they eat the fish. Garbage also fouls the ocean. Many plastic bottles and other pieces of trash are thrown overboard from boats. The wind blows trash out to sea. Ocean currents carry plastics and other floating trash to certain places on the globe, where it cannot escape. The largest of these areas, called the Great Pacific Garbage Patch, is in a remote part of the Pacific Ocean. According to some estimates, this garbage patch is the size of Texas. The trash is a threat to fish and seabirds, which mistake the plastic for food. Many of the plastics are covered with chemical pollutants. Land Pollution Many of the same pollutants that foul the water also harm the land. Mining sometimes leaves the soil contaminated with dangerous chemicals. Pesticides and fertilizers from agricultural fields are blown by the wind. They can harm plants, animals, and sometimes people. Some fruits and vegetables absorb the pesticides that help them grow. When people consume the fruits and vegetables, the pesticides enter their bodies. Some pesticides can cause cancer and other diseases. A pesticide called DDT (dichlorodiphenyltrichloroethane) was once commonly used to kill insects, especially mosquitoes. In many parts of the world, mosquitoes carry a disease called malaria , which kills a million people every year. Swiss chemist Paul Hermann Muller was awarded the Nobel Prize for his understanding of how DDT can control insects and other pests. DDT is responsible for reducing malaria in places such as Taiwan and Sri Lanka. In 1962, American biologist Rachel Carson wrote a book called Silent Spring , which discussed the dangers of DDT. She argued that it could contribute to cancer in humans. She also explained how it was destroying bird eggs, which caused the number of bald eagles, brown pelicans, and ospreys to drop. In 1972, the United States banned the use of DDT. Many other countries also banned it. But DDT didn’t disappear entirely. Today, many governments support the use of DDT because it remains the most effective way to combat malaria. Trash is another form of land pollution. Around the world, paper, cans, glass jars, plastic products, and junked cars and appliances mar the landscape. Litter makes it difficult for plants and other producers in the food web to create nutrients . Animals can die if they mistakenly eat plastic. Garbage often contains dangerous pollutants such as oils, chemicals, and ink. These pollutants can leech into the soil and harm plants, animals, and people. Inefficient garbage collection systems contribute to land pollution. Often, the garbage is picked up and brought to a dump, or landfill . Garbage is buried in landfills. Sometimes, communities produce so much garbage that their landfills are filling up. They are running out of places to dump their trash. A massive landfill near Quezon City, Philippines, was the site of a land pollution tragedy in 2000. Hundreds of people lived on the slopes of the Quezon City landfill. These people made their living from recycling and selling items found in the landfill. However, the landfill was not secure. Heavy rains caused a trash landslide, killing 218 people. Sometimes, landfills are not completely sealed off from the land around them. Pollutants from the landfill leak into the earth in which they are buried. Plants that grow in the earth may be contaminated, and the herbivores that eat the plants also become contaminated. So do the predators that consume the herbivores. This process, where a chemical builds up in each level of the food web, is called bioaccumulation . Pollutants leaked from landfills also leak into local groundwater supplies. There, the aquatic food web (from microscopic algae to fish to predators such as sharks or eagles) can suffer from bioaccumulation of toxic chemicals. Some communities do not have adequate garbage collection systems, and trash lines the side of roads. In other places, garbage washes up on beaches. Kamilo Beach, in the U.S. state of Hawai'i, is littered with plastic bags and bottles carried in by the tide . The trash is dangerous to ocean life and reduces economic activity in the area. Tourism is Hawai'i’s largest industry . Polluted beaches discourage tourists from investing in the area’s hotels, restaurants, and recreational activities. Some cities incinerate , or burn, their garbage. Incinerating trash gets rid of it, but it can release dangerous heavy metals and chemicals into the air. So while trash incinerators can help with the problem of land pollution, they sometimes add to the problem of air pollution. Reducing Pollution Around the world, people and governments are making efforts to combat pollution. Recycling, for instance, is becoming more common. In recycling, trash is processed so its useful materials can be used again. Glass, aluminum cans, and many types of plastic can be melted and reused . Paper can be broken down and turned into new paper. Recycling reduces the amount of garbage that ends up in landfills, incinerators, and waterways. Austria and Switzerland have the highest recycling rates. These nations recycle between 50 and 60 percent of their garbage. The United States recycles about 30 percent of its garbage. Governments can combat pollution by passing laws that limit the amount and types of chemicals factories and agribusinesses are allowed to use. The smoke from coal-burning power plants can be filtered. People and businesses that illegally dump pollutants into the land, water, and air can be fined for millions of dollars. Some government programs, such as the Superfund program in the United States, can force polluters to clean up the sites they polluted. International agreements can also reduce pollution. The Kyoto Protocol , a United Nations agreement to limit the emission of greenhouse gases, has been signed by 191 countries. The United States, the world’s second-largest producer of greenhouse gases, did not sign the agreement. Other countries, such as China, the world’s largest producer of greenhouse gases, have not met their goals. Still, many gains have been made. In 1969, the Cuyahoga River, in the U.S. state of Ohio, was so clogged with oil and trash that it caught on fire. The fire helped spur the Clean Water Act of 1972. This law limited what pollutants could be released into water and set standards for how clean water should be. Today, the Cuyahoga River is much cleaner. Fish have returned to regions of the river where they once could not survive. But even as some rivers are becoming cleaner, others are becoming more polluted. As countries around the world become wealthier, some forms of pollution increase. Countries with growing economies usually need more power plants, which produce more pollutants. Reducing pollution requires environmental, political, and economic leadership. Developed nations must work to reduce and recycle their materials, while developing nations must work to strengthen their economies without destroying the environment. Developed and developing countries must work together toward the common goal of protecting the environment for future use.

How Long Does It Last? Different materials decompose at different rates. How long does it take for these common types of trash to break down?

Indoor Air Pollution The air inside your house can be polluted. Air and carpet cleaners, insect sprays, and cigarettes are all sources of indoor air pollution.

Light Pollution Light pollution is the excess amount of light in the night sky. Light pollution, also called photopollution, is almost always found in urban areas. Light pollution can disrupt ecosystems by confusing the distinction between night and day. Nocturnal animals, those that are active at night, may venture out during the day, while diurnal animals, which are active during daylight hours, may remain active well into the night. Feeding and sleep patterns may be confused. Light pollution also indicates an excess use of energy. The dark-sky movement is a campaign by people to reduce light pollution. This would reduce energy use, allow ecosystems to function more normally, and allow scientists and stargazers to observe the atmosphere.

Noise Pollution Noise pollution is the constant presence of loud, disruptive noises in an area. Usually, noise pollution is caused by construction or nearby transportation facilities, such as airports. Noise pollution is unpleasant, and can be dangerous. Some songbirds, such as robins, are unable to communicate or find food in the presence of heavy noise pollution. The sound waves produced by some noise pollutants can disrupt the sonar used by marine animals to communicate or locate food.

Essay on Pollution: Samples in 100, 150 and 200 Words

Updated on
Nov 23, 2023

As the world embraced urbanization, mother nature witnessed the greener lands getting transformed into modern cities and metropolises. What followed is a trail of natural disasters signalling that something is wrong with the planet earth. Pollution is increasingly asked under the writing section in school and college tests as well as competitive exams . This is because it is a relevant environmental issue today. This blog aims to help you with the necessary knowledge as well as tips and tricks to draft a well-written essay on pollution.

What is Pollution?

Pollution is the introduction of harmful materials into the environment. These materials are called pollutants. They can be created by human activity like trash and natural like volcanic ash. Pollutants damage the quality of water, air and land. Pollution is a global problem. Air and water carry pollution into the ocean currents and migrating fish. Pollution is among the many things that harm our planet- once greener and healthier than it is now. Pollution is a dangerous phenomenon that is contributing to an array of health issues.

Types of Pollution

In simple terms, pollution is defined as the contamination of the physical and biological constituents in the earth’s atmosphere. It affects human life and the natural environment to a very great extent. It degrades our natural resources, from the water we drink to the air we breathe. While writing an essay on Pollution, you must mention the major four types of pollution which are as follows:

Air Pollution : Air pollution is the contamination of air in the atmosphere when harmful or excessive quantities of substances such as smoke and harmful gases from industries, CFCs and oxides produced by automobiles, the burning of solid wastes, etc. are introduced into the environment.
Water Pollution : This refers to the contamination of natural resources of water, due to the addition of harmful chemical, biological or physical materials, which includes industrial wastes, oil spills, domestic and farm wastes, pesticides, as well as mining and agricultural wastes, to water resource which make it unusable.
Soil Pollution : Land/Soil Pollution occurs due to the degradation of the earth’s surface by different commercial, industrial, agricultural and domestic activities. Causes of soil pollution also include mining, deforestation, dumping of e-waste and other industrial wastes, usage of harmful chemicals such as insecticides, pesticides, etc.
Noise Pollution : Excess noise due to sounds created by machines, loudspeakers, microphones, loud music, noise from industries, construction and civil engineering works etc. lead to noise pollution.

Add the causes and effects in your essay on Pollution depending upon the word limit allowed to you.

Format for Essay on Pollution

Before writing an essay on Pollution, students must be familiarised with the format of essay writing. The key elements of the essay format are Introduction, Body of Content and Conclusion. Take a look at the following paragraphs which delve deeper into the details of these features as per a 200-250 word essay:

Introduction – The introduction of the essay must be on providing an overview of the given topic. For an essay on Pollution, you can begin with a simple definition or thought-provoking sentence and complete it in about around 60 words. Since, it is the first thing the reader looks at, try to make it interesting by adding recent instances and impactful questions.
Body of Content – This area of the content comes after the introduction and can be explained in around 100-120 words, describing the given topic in detail. So, in writing about pollution, you can describe how the atmosphere and the environment are getting affected due to Pollution and list down various ways to prevent pollution.
Conclusion – Wrapping up your essay, this part comprises around 50 words. Try to bring a positive outlook on the issue you are discussing or conclude by summing up in a concise way.

Sample Essay on Pollution in 100 Words

Polllution is the addition of unwanted susbstances which are incorporated into the environment that can damage our Earth. There are mainly four tyoes of pollutions, these inlcude water pollution, air pollution, soil pollution, and noise pollution. One should note that any form of pollution is the result of careless activity carried out by man. We, humans on a daily basis dump waste directly into water bodies which leads to water pollution. Vehicle emissions of smoke into the atmosphere impede the ability of all living things to breathe, leading to air pollution. Our garbage is dumped into landfills directly, which results in soil pollution. Although it cannot be seen, noise pollution is a severe type of pollution that can harm our ears.

Sample Essay on Pollution in 250- 300 Words

The biggest threat planet earth is facing is pollution. Unwanted substances leave a negative impact once released into an environment. There are four types of pollution air, water, land, and noise. Pollution affects the quality of life more than any human can imagine. Due to air pollution, even teenage kids have developed various respiratory diseases. Water pollution has led to diseases in children. The waste we humans dump on the land or chemical fertilisers which are put on the land for agricultural purposes causes land/ soil pollution. If the soil quality deteriorates due to such practices, the soil will become infertile and no crops could be grown in future. The government has launched various schemes over the years to fight pollution but individual efforts can also play a vital role. Start by replacing plastic bags for shopping with cloth bags, stopping littering on roads and stop wasting water are some of the basic things to start with that can lead to big changes in the environment.

Sample Essay on Pollution in 300-350 Words

One of the most critical threats faced by our planet in the present day scenario. Environmental pollution is a global issue affecting people around the world. It is occurring in different forms, whether by affecting the air we breathe or the water resources we utilise for several purposes. Air pollution came into being with an increase in the level of carbon dioxide, with the increase in pollutants which are contaminating the air and causing breathing discomfort as well as skin diseases to human beings. Talking about the other aspect, there is no life without water. The water bodies are polluting and becoming unsafe for drinking or any other use because of industrial development, rapid urbanisation and various other reasons. Due to air pollution, diseases that can occur to human beings are asthma, various skin diseases, cancer, etc. Therefore, it is the essential need of the hour to take serious steps to reduce pollution to its core. At a personal level, we can minimise environmental pollution by taking public transport or carpools to reduce vehicular smoke, avoiding firecrackers at festivals and celebrations can also cut down on air and noise pollution, and not using fertilisers and pesticides which can cause both water and soil pollution, and switching over to organic farming. The government can also bring strict rules and regulations to lessen industrial pollution. To sum up, any type of pollution is harmful to the environment with serious consequences like global warming, uneven climatic changes, etc. Due to our greediness and illegal human activities, the innocent lives of animals are lost. The time has come to join our hands and work towards preserving and protecting the environment for the present as well as future generations.

How to Reduce or Prevent Pollution?

Everyone has a responsibility to take action to prevent pollution after learning about its negative impacts. Every preventive measure that can be taken to lessen pollution should be known to us. For example, to reduce air pollution, we should refrain from lighting fireworks during festivals, take public transportation or carpool, limit the use of loudspeakers, and reduce noise pollution by honking in public. This circumstance should always be on our minds so that we can respond appropriately. In the beginning, it is up to us to exercise caution and to raise awareness among those around us. We should take environmentally beneficial measures, such as increasing tree planting, lowering plastic usage, utilising more sustainable household products, etc. Always keep in mind that every tiny action now will have a greater effect tomorrow when discussing global pollution.

Tips on Reducing Pollution

Say NO to Crackers
Use Public Transportation
Turn off the lights, fans and water taps when not in use
Recycle and Reuse
Segregate your waste
Say NO to Plastic
Plant more trees
Use of fans instead of ACs

Pollution’s Vicious Cycle

Pollution’s Vicious Cycle: Unraveling Causes and Effects on Our Environment

Thesis statement: “Looking at the multiple causes and pervasive effects of pollution on our environment, this essay contends that the interconnection of industrial emissions, improper waste disposal, agricultural practices, and deforestation forms a vicious cycle that is composed of air and water quality, disrupts ecosystems, and exacerbates climate change.”

Introduction

In today’s world, pollution has become a big and threatening problem because of factories and what people do. This essay will explore several factors that lead to pollution and how badly it affects nature, people’s health, and the balance of our planet. Acknowledging complexity and interconnectedness of these factors is crucial to develop solutions that are comprehensive and sustainable in nature. Moreover, they address the root causes leading to pollution and strive for a healthier planet.

Cause 1- Industrial Emissions and Air Pollution

However crucial industrial activities are for economic development, they come with a major drawback, releasing pollutants in the atmosphere. From greenhouse gasses like carbon dioxide (CO2) to particulate matter and harmful chemicals, these emissions combine to create a toxic mix that tampers with the composition of the air. There is no doubt that the fast paced industrial expansion has added to the industry but simultaneously it has added to the air pollution as well.

Effects of Industrial Emissions and Air Pollution

Deterioration of air quality.

The biggest effect of industrial emissions is the constant release of pollutants into that air which deteriorates air quality, resulting in smog, reduced visibility, and adverse effects on human and animal health. It also gives rise to respiratory issues, cardiovascular problems, and an increased risk of lung diseases. Such issues become prevalent in areas with high industrial emissions with increased levels of air pollution. Furthermore, when there are more greenhouse gasses, global warming gets worse, leading to climate change and its widespread effects.

Acid Rain Formation

There are certain industrial emissions, sulfur dioxide (SO2) and nitrogen oxides (NOx) in particular that combine with atmospheric moisture to form acid rain. The acidic precipitation is an imperative threat to aquatic ecosystems because it damages soil quality, and adds to the degradation of natural habitats. The far reaching effects of acid rain underscore the interconnectedness of atmospheric and terrestrial systems.

Cause 2 – Improper Waste Disposal and Water Pollution

Improper disposal of waste, including plastics, chemicals, and other pollutants, contaminates water bodies, which is life threatening in nature especially when it comes to the aquatic ecosystems and human health. Irrespective of the fact that there are proper disposal bins in place, still people tend to dispose of waste in improper ways without caring about the adverse effects.

Effect of Improper Waste Disposal and Water Pollution

Contaminated drinking water.

Water pollution jeopardizes the safety of drinking water sources, exposing communities to health risks such as waterborne diseases. This contaminated water eventually becomes a breeding ground for pathogens, adversely affecting the health and well-being of populations relying on these water sources.

Marine Ecosystem Degradation

Pollutants discharged into oceans and waterways lead to the degradation of marine ecosystems. Plastic waste, in particular, is a severe threat to marine biodiversity as marine species ingest or become entangled in debris. The far-reaching consequences extend to ecosystems that are dependent on healthy oceans for their ecological balance.

Cause 3 – Agricultural Runoff and Soil Pollution

When it comes to intensive agricultural practices that involve using fertilizers and pesticides contribute to runoff, carrying harmful substances into water bodies and degrading soil quality. To increase the production of crops and increase the yearly yield, the farmers have been using more of the fertilizers and pesticides.

Effects of Agricultural Runoff and Soil Pollution

Eutrophication of water bodies.

When agricultural runoff introduces excess nutrients into water bodies, it leads to eutrophication. This process causes algal blooms, depleting oxygen levels in the water which eventually result in “dead zones”, a place where aquatic life cannot thrive. The impact is felt across entire aquatic ecosystems, affecting the delicate balance of flora and fauna. This phenomenon disrupts the balance of nature in a way that is difficult to reverse.

Soil Degradation and Loss of Biodiversity

The use of agrochemicals contributes to soil pollution, affecting soil fertility and the overall health of ecosystems. Soil degradation results in the loss of biodiversity, impacting plant and animal species dependent on healthy soil conditions. The ramifications extend beyond agriculture to encompass entire ecosystems. Basically, one thing leads to another and disrupts the smooth runnings of nature.

Cause 4 – Deforestation and Loss of Green Cover

Widespread deforestation, driven by urbanization and agricultural expansion, reduces the planet’s capacity to absorb carbon dioxide and disrupts ecosystems. Even though people know that forests and green areas are good for humans and animals, they still chop down trees to construct buildings and roads.

Effects Deforestation and Loss of Green Cover

Increased greenhouse gas emissions.

Cutting down too many trees adds more carbon dioxide to the air, making the greenhouse effect and climate change worse. Forests, which soak up carbon, disappearing makes human activities affect global temperatures even more. This connection shows how important forests are in lessening the bad effects of climate change.

Disruption of Ecosystem Services

Chopping down trees and ruining natural homes messes up important things nature does for us. Cleaning the air and water, helping plants grow, and keeping many different types of living things are all affected. This doesn’t just hurt the places where trees are cut down but also harms the whole interconnected system of life that depends on these helpful things from nature.

Pollution creates a complicated cycle that upsets the balance of our planet. To fix pollution, we need to do many things like using sustainable practices, managing waste responsibly, and everyone worldwide committing to taking care of the environment. Understanding how everything people do affects the environment is crucial to stop the cycle of pollution and make a better, more lasting future. The message is clear: we must all work together to lessen the reasons and effects of pollution, making a global promise to keep our planet healthy for the future.

Causes of Pollution Essay

Pollution is the result of dangerous compounds, or pollutants, interacting with the elements of the natural environment. There are many different types of pollution—soil, air, water, and land pollution. Whatever type of pollution it is, it has a negative impact on our environment, people, animals and ecosystem as a whole. Here are some essays on ‘Causes of Pollution’ that students can refer to for their school assignments and projects.

100 Words Essay Causes of Pollution

200 words essay causes of pollution, 500 words essay causes of pollution.

Pollution is the release of undesired elements into the environment, which can harm our planet. Water pollution, air pollution, soil contamination, and noise pollution are the four basic forms of pollution. Our reckless actions have resulted in pollution of many types. We directly dump waste into bodies of water, which causes water contamination. Vehicles and Industrial waste that emit smoke into the air generate air pollution, which makes it difficult for all living things to breathe. Directly depositing the waste into landfills leads to soil pollution. Although it cannot be seen, noise pollution is a severe type of pollution that can harm our ears.

Environmental pollution is caused by a variety of human activities. Global population growth and widespread development have led to a rise in human activity, including deforestation, industrialization, and urbanisation, among other things. Each of these activities has a different impact on the environment. For example, industrialization pollutes air and water bodies because manufacturing sectors produce a large amount of harmful pollutants in both gaseous and liquid forms. Lack of effective management causes these contaminants to be released into the environment, causing pollution of the air and water sources. Similarly, vehicles used for transportation run on fossil fuels, which when burned release dangerous chemicals like Carbon Monoxide, Carbon Dioxide etc.

These gases then interact with the atmosphere, generating air pollution that is the cause for several respiratory diseases and also result in genetic problems in both plants and animals. Even while human actions like deforestation didn't directly cause pollution, they nonetheless make the planet less able to combat it. Natural air filters and buffer zones are provided by forests. In addition to absorbing noise pollution, they also convert carbon dioxide into vital oxygen. When more forests are destroyed, the concentration of these harmful chemicals in the atmosphere rises, which has a negative impact on both human and animal health.

The natural order of our ecosystems has been disturbed by pollution, which has had serious negative impacts on the inhabitants of Earth. Unchecked and unlawful activities that abuse natural resources and disregard regulations established by pollution control boards around the nation are the main cause of pollution. A pollutant can be in any form. It might be a liquid, a solid, or even a gas. No matter what condition the pollutant is in, if it is not controlled, it could have catastrophic repercussions on our natural ecosystem.

Factors Leading To Pollution

We've covered a few of the key causes of environmental contamination below. All of the elements are related to human activities and the human desire to extend, explore, and grow.

Plastic Usage | One of the primary contributors to environmental degradation is the excessive use of plastic in consumable products like bags and other consumable materials. Plastic is not biodegradable and will remain in the environment in its current form for generations. Thin plastic bags shatter into tiny fragments that end up in the land and water bodies, polluting them.

Industrialisation | Our pursuit of economic development has given rise to several industries around the world. As a result, many manufacturing businesses release harmful gases into the atmosphere. Industrial emissions may also include solids, chemicals, and harmful gases. These compounds are freely released into the environment by industries due to a lack of appropriate policies, which in turn results in environmental damage.

Fossil Fuels | The primary fuel for transportation vehicles is fossil fuels. Carbon dioxide and carbon monoxide are byproducts of burning fossil fuels. The quantity of these harmful chemicals in the atmosphere increases as the number of automobiles on the road increases. Additionally, businesses that produce fossil fuels release toxic gaseous compounds that are particularly bad for the environment.

Heavy Machinery And Development | Every minute, new buildings are being built; within a few hours, people and equipment can be transported between locations using large jet liners and transportation vehicles. The biggest sources of noise pollution are these large equipment used in construction and aircrafts. Despite not being as serious as air and water pollution, noise pollution nevertheless has a negative influence on both the environment and human health.

Agricultural Activities | Agricultural practices, such as the use of chemical fertilisers, damage the soil, causing soil pollution. Modern fertilisers contain chemicals that, while temporarily increasing crop productivity, are bad for the environment in the long run. These substances mix with the soil and are later carried away by runoff into our surface and groundwater supplies.

How To Combat Pollution

After becoming aware of the damaging effects of pollution, everyone has a duty to take steps to prevent it. We should be aware of every precaution that can be taken to reduce pollution. For instance, we should avoid using fireworks during celebrations, use public transit or carpool, use loudspeakers sparingly, and stop from honking in public to lessen noise pollution. We must keep this situation in mind at all times so that we can react appropriately. It is our responsibility to practise caution and spread awareness among people around us at first. We should take actions that are good for the environment, including planting more trees, using less plastic, using more eco-friendly household items, etc.When addressing global pollution, always keep in mind that every small action now will have a greater impact tomorrow.

Essay on Air Pollution for Students and Children

500+ words essay on air pollution.

Essay on Air Pollution – Earlier the air we breathe in use to be pure and fresh. But, due to increasing industrialization and concentration of poisonous gases in the environment the air is getting more and more toxic day by day. Also, these gases are the cause of many respiratory and other diseases . Moreover, the rapidly increasing human activities like the burning of fossil fuels, deforestation is the major cause of air pollution.

How Air Gets Polluted?

The fossil fuel , firewood, and other things that we burn produce oxides of carbons which got released into the atmosphere. Earlier there happens to be a large number of trees which can easily filter the air we breathe in. But with the increase in demand for land, the people started cutting down of trees which caused deforestation. That ultimately reduced the filtering capacity of the tree.

Moreover, during the last few decades, the numbers of fossil fuel burning vehicle increased rapidly which increased the number of pollutants in the air .

Causes Of Air Pollution

Its causes include burning of fossil fuel and firewood, smoke released from factories , volcanic eruptions, forest fires, bombardment, asteroids, CFCs (Chlorofluorocarbons), carbon oxides and many more.

Besides, there are some other air pollutants like industrial waste, agricultural waste, power plants, thermal nuclear plants, etc.

Greenhouse Effect

The greenhouse effect is also the cause of air pollution because air pollution produces the gases that greenhouse involves. Besides, it increases the temperature of earth surface so much that the polar caps are melting and most of the UV rays are easily penetrating the surface of the earth.

Effects Of Air Pollution On Health

Moreover, it increases the rate of aging of lungs, decreases lungs function, damage cells in the respiratory system.

Ways To Reduce Air Pollution

Although the level of air pollution has reached a critical point. But, there are still ways by which we can reduce the number of air pollutants from the air.

Reforestation- The quality of air can be improved by planting more and more trees as they clean and filter the air.

Policy for industries- Strict policy for industries related to the filter of gases should be introduced in the countries. So, we can minimize the toxins released from factories.

Use of eco-friendly fuel- We have to adopt the usage of Eco-friendly fuels such as LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), bio-gas, and other eco-friendly fuels. So, we can reduce the amount of harmful toxic gases.

To sum it up, we can say that the air we breathe is getting more and more polluted day by day. The biggest contribution to the increase in air pollution is of fossil fuels which produce nitric and sulphuric oxides. But, humans have taken this problem seriously and are devotedly working to eradicate the problem that they have created.

Above all, many initiatives like plant trees, use of eco-friendly fuel are promoted worldwide.

4 Causes and Effects of Air Pollution

Air pollution refers to the release of pollutants into the air, which can be harmful and impose significant health risks to the population, including increased chances of coronary and respiratory diseases, as well as preliminary deaths. Made up of chemicals and pollutant particles, air pollution is one of the biggest environmental problems of our lifetime . Read on to learn about the major causes and effects of air pollution.

Sources of Air Pollution

1. burning fossil fuels.

The biggest contributors of air pollution are from industry sources and power plants to generate power, as well as fossil fuel motor vehicles. The continuous burning of fossil fuels releases air pollutants, emissions and chemicals into the air and atmosphere.

In 2020, the Environmental Protection Agency reported that about 68 million tons of air pollution were emitted into the atmosphere in the US, contributing to the “formation of ozone and particles, the deposition of acids, and visibility impairment.”

The World Health Organization (WHO) estimates around 91% of the world’s population lives in places where air quality levels exceed limits. Developing and low-income countries experienced the greatest impacts from outdoor air pollution, particularly in the Western Pacific and South-East Asia regions.

Climate change has an interrelated relationship with the environment and air pollution. As more air pollutants and greenhouse gases are released, this alters the energy balance between the atmosphere and the Earth’s surface , which leads to global warming. The global temperature increase in turns raises the production of allergenic air pollutants such as mold and extends pollen seasons.

2. Ozone and Smog

Ozone is a gas that when it forms air pollution and reaches too close to the ground, it significantly reduces visibility. We call this smog. This form of air pollution occurs when sunlight reacts with nitrogen oxides released from car exhausts and coal power plants. The ozone typically forms a protective layer in the atmosphere to protect the population from ultraviolet radiation (UV), but as it transforms into smog, it is harmful to human health and poses higher risks of respiratory illnesses like asthma and lung cancer.

3. Weather Conditions

Air pollution and poor air quality can be attributed to changing weather conditions. For example, dust storms in China would carry clouds of industrial pollutants and particulate pollution across the Gobi desert into neighbouring countries such as Korea and Japan during spring season. Likewise during periods of high air pressure, air becomes stagnant and pollutants are more concentrated over certain areas.

4. Heatwaves and Wildfires

Heatwaves not only lead to an increase of temperature, but are some of the causes and effects of air pollution. Hotter, stagnant air during a heat wave increases the concentration of particle pollutants. Extreme heat wave events also have higher risks of large-scale wildfires, which in turn, releases more carbon emissions, smog and pollutants into the air.

Effects of Air Pollution

Air pollution contributes to the death of 5 million every year and about 6% of the global population, according to Our World in Data . The lethal combination of outdoor air pollution and toxic emissions from burning fossil fuel has been one of the leading causes of chronic and often terminal health issues including heart disease, stroke, lung cancer, and lower respiratory infections.

The WHO estimates that nine out of 10 people breathe air that contains high levels of pollutants. In 2017, close to 15% of population deaths in low income countries like South and East Asia are attributed to air pollution, while the higher income countries experience only about 2%.

The drastic difference in mortality numbers can be linked to legislations such as the Clean Air Act implemented by high-income countries like the US. Such legislations usually establishes national air quality standards and regulations on hazardous air pollutants. The UK in particular, saw a sharp 60% decline in air pollutant emissions between the 1970 and 2016.

The environmental effects of air pollution are also vast, ranging from acid rain to contributing to birth defects, reproductive failure, and diseases in wildlife animals. Agriculture is also a victim of air pollution as increased pollutants can affect crop and forest yields, reduce growth and increased plant susceptibility to disease from increased UV radiation caused by ozone depletion.

In the wake of the COVID-19 pandemic, air pollution has once again returned to the spotlight in relation to its role in transmitting virus molecules. Preliminary studies have identified a positive correlation between COVID-19-related mortalities and air pollution. China, being one of the most polluted countries in the world, can potentially link its high death toll during the pandemic to its poor air quality. Although, more research needs to be conducted to make any substantive correlation.

Environmental Pollution Essay

Essay on Environmental Pollution

The environment is the surrounding of an organism. The environment in which an organism lives is made up of various components like air, water, land, etc. These components are found in fixed proportions to create a harmonious balance in the environment for the organism to live in. Any kind of undesirable and unwanted change in the proportions of these components can be termed as pollution. This issue is increasing with every passing year. It is an issue that creates economic, physical, and social troubles. The environmental problem that is worsening with each day needs to be addressed so that its harmful effects on humans as well as the planet can be discarded.

Causes of Environmental Pollution

With the rise of the industries and the migration of people from villages to cities in search of employment, there has been a regular increase in the problem of proper housing and unhygienic living conditions. These reasons have given rise to factors that cause pollution.

Environmental pollution is of five basic types namely, Air, Water, Soil, and Noise pollution.

Air Pollution: Air pollution is a major issue in today’s world. The smoke pouring out of factory chimneys and automobiles pollute the air that we breathe in. Gases like carbon dioxide, carbon monoxide, and sulphur dioxide are emitted with this smoke which mixes with air and causes great harm to the human body, flora, and fauna. The dry-farm waste, dry grass, leaves, and coal used as domestic fuels in our villages also produce harmful gases. Acid rain occurs due to an excess of sulphur dioxide in the air.

The Main Sources of Air Pollution are as Follows:

Automobile pollution

Industrial air pollution

Burning garbage

Brick kilns

Indoor air pollution

Decomposed animals and plants

Radioactive elements

Water Pollution: Water pollution is one of the most serious environmental issues. The waste products from the growing industries and sewage water are not treated properly before disposing of the wastewater into the rivers and other water bodies, thus leading to water pollution. Agricultural processes with excess fertilizers and pesticides also pollute the water bodies.

The Main Sources of Water Pollution as Follows:

Marine commerce.

Industrial effluents joining seas and oceans.

Dumping of radioactive substances into seawater.

Sewage is disposed of into the sea by rivers.

Offshore oil rigs.

Recreational activities.

Agricultural pollutants are disposed of into the water bodies.

Soil or Land Pollution: Soil pollution or land pollution results from the deposition of solid waste, accumulation of biodegradable material, deposition of chemicals with poisonous chemical compositions, etc on the open land. Waste materials such as plastics, polythene, and bottles, cause land pollution and render the soil infertile. Moreover, the dumping of dead bodies of animals adds to this issue. Soil pollution causes several diseases in man and animals like Cholera, Dysentery, Typhoid, etc.

The Main Causes of Soil Pollution are as Follows:

Industrial waste

Urban commercial and domestic waste

Chemical fertilizers

Biomedical waste

Noise Pollution: With an increasing population, urbanization, and industrialization, noise pollution is becoming a serious form of pollution affecting human life, health, and comfort in daily life. Horns of vehicles, loudspeakers, music systems, and industrial activities contribute to noise pollution.

The Main Sources of Noise Pollution as Follows:

The machines in the factories and industries produce whistling sounds, crushing noise, and thundering sounds.

Loudspeakers, horns of vehicles.

Blasting of rocks and earth, drilling tube wells, ventilation fans, and heavy earth-moving machinery at construction sites.

How Pollution Harms Health and Environment

The lives of people and other creatures are affected by environmental pollution, both directly and indirectly. For centuries, these living organisms have coexisted with humans on the planet.

1. Effect on the Environment

Smog is formed when carbon and dust particles bind together in the air, causing respiratory problems, haze, and smoke. These are created by the combustion of fossil fuels in industrial and manufacturing facilities and vehicle combustion of carbon fumes.

Furthermore, these factors impact the immune systems of birds, making them carriers of viruses and diseases. It also has an impact on the body's system and organs.

2. Land, Soil, and Food Effects

The degradation of human organic and chemical waste harms the land and soil. It also releases chemicals into the land and water. Pesticides, fertilisers, soil erosion, and crop residues are the main causes of land and soil pollution.

3. Effects on water

Water is easily contaminated by any pollutant, whether it be human waste or factory chemical discharge. We also use this water for crop irrigation and drinking. They, too, get polluted as a result of infection. Furthermore, an animal dies as a result of drinking the same tainted water.

Furthermore, approximately 80% of land-based pollutants such as chemical, industrial, and agricultural waste wind up in water bodies.

Furthermore, because these water basins eventually link to the sea, they contaminate the sea's biodiversity indirectly.

4. Food Reaction

Crops and agricultural produce become poisonous as a result of contaminated soil and water. These crops are laced with chemical components from the start of their lives until harvest when they reach a mass level. Due to this, tainted food has an impact on our health and organs.

5. Climate Change Impact

Climate change is also a source of pollution in the environment. It also has an impact on the ecosystem's physical and biological components.

Ozone depletion, greenhouse gas emissions, and global warming are all examples of environmental pollution. Because these water basins eventually link to the sea, they contaminate the sea's biodiversity indirectly. Furthermore, their consequences may be fatal for future generations. The unpredictably cold and hot climate impacts the earth’s natural system.

Furthermore, earthquakes, starvation, smog, carbon particles, shallow rain or snow, thunderstorms, volcanic eruptions, and avalanches are all caused by climate change, caused entirely by environmental pollution.

How to Minimise Environmental Pollution?

To minimise this issue, some preventive measures need to be taken.

Principle of 3R’s: To save the environment, use the principle of 3 R’s; Reuse, Reduce and Recycle.

Reuse products again and again. Instead of throwing away things after one use, find a way to use them again. Reduce the generation of waste products.

Recycle: Paper, plastics, glass, and electronic items can be processed into new products while using fewer natural resources and lesser energy.

To prevent and control air pollution, better-designed equipment, and smokeless fuels should be used in homes and industries. More and more trees should be planted to balance the ecosystem and control greenhouse effects.

Noise pollution can be minimised by better design and proper maintenance of vehicles. Industrial noise can be reduced by soundproofing equipment like generators, etc.

To control soil pollution, we must stop the usage of plastic. Sewage should be treated properly before using it as fertilizers and as landfills. Encourage organic farming as this process involves the use of biological materials and avoiding synthetic substances to maintain soil fertility and ecological balance.

Several measures can be adopted to control water pollution. Some of them are water consumption and usage that can be minimized by altering the techniques involved. Water should be reused with treatment.

The melting icebergs in Antarctica resulted in rising sea levels due to the world's environmental pollution, which had become a serious problem due to global warming, which had become a significant concern. Rising carbon pollution poses a risk for causing natural disasters such as earthquakes, cyclones, and other natural disasters.

The Hiroshima-Nagasaki and Chernobyl disasters in Russia have irreversibly harmed humanity. Different countries around the world are responding to these calamities in the most effective way possible.

Different countries around the world are responding to these calamities in the most effective way possible. More public awareness campaigns are being established to educate people about the hazards of pollution and the importance of protecting our environment. Greener lifestyles are becoming more popular; for example, energy-efficient lighting, new climate-friendly autos, and the usage of wind and solar power are just a few examples.

Governments emphasise the need to plant more trees, minimise the use of plastics, improve natural waste recovery, and reduce pesticide use. This ecological way of living has helped humanity save other creatures from extinction while making the Earth a greener and safer ecology.

Conclusion

It is the responsibility of every individual to save our planet from these environmental contamination agents. If preventive measures are not taken then our future generation will have to face major repercussions. The government is also taking steps to create public awareness. Every individual should be involved in helping to reduce and control pollution.

Causes of Pollution Essay 1 (200 Words)

There are several human activities that lead to the pollution of the environment. Widespread development and population growth throughout the world has resulted in increased human activities like industrialization, urbanization, deforestation among others.

Each of stated activities affects the environment in its own way. For example, industrialization causes the contamination of air and water bodies, as a lot of toxic byproducts are produced both in gaseous as well as liquid forms, by the production industries. In the absence of proper management, these pollutants are left into the environment, resulting in pollution of air and water bodies.

Similarly, transport vehicles use fossil fuel, which on burning produces harmful gases like CO (Carbon Monoxide), CO 2 (Carbon dioxide) etc. These gases again mix with the atmospheric air, causing air pollution.

Human activities like deforestation didn’t directly contribute to the pollution; nevertheless it reduces the earth’s capacity to tackle with pollution. Forests act as natural buffer zones and air filters. They absorb noise pollution and also exchange CO 2 with much needed O 2 (Oxygen). When more forests are cut down it results in increased atmospheric concentration of these toxic gases, which has a adverse effect on human health as well as on the health of the flora and fauna.

Causes of Pollution Essay 2 (300 Words)

Introduction

When an unwanted substance enters the otherwise natural and pure environment, this phenomenon is termed as pollution. There are many factors that cause pollution and almost all of them are human induced. The natural pollutants causing potential harm to the environment are negligible.

Causes of Pollution

Below we have discussed some of the main factors causing pollution of the environment. All of the factors involve human activities and man’s need to expand, explore and grow.

1) Industrialization

Man’s quest for economical growth has led to cluster of industries all over the globe. These manufacturing industries emit toxic fumes as byproduct, which are emitted into the environment.

Industrial emission may contain toxic gases, chemicals and solids as well. Due to lack of effective policies, these substances are freely emitted into the environment, by the industries, consequently causing environmental pollution.

2) Use of Fossil Fuel

Transportation vehicles use fossil fuels as their main fuel. Burning of fossil fuels produces gases like Carbon dioxide (CO 2 ) and Carbon Monoxide (CO) as byproduct. More number of vehicles plying on road means more quantity of these toxic gases in the atmosphere.

Also the industries producing fossil fuels generate toxic gaseous compound which are very harmful to the environment.

3) Littering

Littering is another most common cause for the environmental pollution. Littering happens when common household waste or urban waste, to be more specific, reaches our natural environment, due to the lack of effective waste management methods.

The urban waste consists of toxic compounds like polythene, glass, lead, garbage etc. This trash reaches our soil and water bodies, resulting in their pollution.

4) Agricultural Activities

Agricultural activities like use of chemical fertilizers contaminate the soil resulting in its pollution. Modern fertilizers use chemicals those may temporary boost up crop yield yet in the long run are harmful to the environment.

These chemicals get mixed with the soil and later get washed away as runoff into our water bodies or ground water resources.

Pollution is a vast subject involving several triggering factors and same as many implications. There is a need to look into each and every factor causing pollution and to take necessary preventive measures.

Causes of Pollution Essay 3 (400 Words)

The causes of pollution are not only limited to the conventional pollutants like Carbon Dioxide (CO 2 ) and Carbon Monoxide (CO) emitted from burning of fossil fuels by transportation vehicles, rather a number of other factors are responsible for causing environmental pollution.

What are the Reasons of Increasing Pollution

Below we have discussed some of the unconventional reasons/causes of pollution.

1) Heavy Machinery and Equipments

I this ever expanding world, new constructions are being build every minute; transportation vehicles and huge jet liners are transporting men and machinery from one place to other within a matter of few hours. These heavy machineries used for the construction work and aircrafts are the main source of noise pollution. Though, noise pollution isn’t considered as serious as air and water pollution, nevertheless it has its own impact on human health and the environment as well.

2) Excessive Use of Light

Excess use of unwanted light in areas of urban settlements causes light pollution. Lights glow up areas where it is not required, often also interfering with each other. Moreover, there are too many lights pointing at a particular place, which requires less light. The presence of excess light over a particular area is termed as light pollution. Though, light is one of the most neglected causes of pollution, yet it has many degrading effects on the environment and its inhabitants.

3) Urban Runoff

Urban runoff is one of the main causes of pollution in and around human settlements. Urban runoff consists of a variety of solid and liquid pollutants, often toxic in nature. It also contains harmful chemicals from agricultural fields using chemical fertilizers. Urban runoff is the main cause of air, water and soil pollution, in and around the urban settlement.

4) Excessive Use of Plastic

Excess use of plastic as bags and in the form of other consumable materials is also one of the main causes of environmental pollution. Plastic is non biodegradable and as it is stays in the environment for centuries to come. Thin plastic bags get broken into small pieces and reaches the soil and water bodies, resulting in their pollution.

Pollution is caused by several human induced activities. There is a need to put an effective policy in place to curb the harmful effect of pollution on the environment. This could only be achieved by sheer will and determination of the government agencies and the people alike.

Causes of Pollution Essay 4 (500 Words)

As we all know that pollution refers to the contamination of our natural environment by an contaminant or pollutant, mainly generated due to human activity. There are some conventional causes of pollution like the use of fossil fuels by vehicles and also non conventional causes like volcanoes, forest fires etc.

Types of Causes of Pollution

The causes of pollution can be classified into two categories – human induced pollution and natural pollution. Below we will briefly discuss the two types of causes of pollution.

Human Induced Pollution

1) Vehicle Exhaust Fumes

Fumes emitted by the exhaust of vehicles are the main cause of air pollution in an urban area. Vehicles use petrol or diesel, which upon combustion produces Carbon Monoxide (CO). CO is toxic in nature and causes irreparable damage to the environment and human health as well.

2) Power Plants

Apart from the vehicles using fossil fuels, power plants also use great quantities of fossil fuels, resulting in environmental damage. During the whole process of fossil fuel burning in a power plant, Sulphur Dioxide (SO 2 ) is produced, which gets mixed with water vapor present in the atmosphere and causes a phenomenon called Acid Rain. Acid Rain is very damaging to the flora and fauna of the environment.

3) Industrial Exhaust

Industrial Exhaust is one of the main causes of pollution of the environment. Industries emit harmful gases as byproducts into the environment. Some of them even release liquid chemical pollutants and other hazardous solid compounds, into the nearby water bodies. This causes huge damage to the natural water resource and contaminates it, also threatening the life of flora and fauna and aquatic plants and animals.

4) Construction Activities

Incessant construction activities are one of the main causes of air pollution in an urban area. Activities like grinding, foundation digging, sump construction, transportation results in very small particles of dust being mixed with air. These particle are called Particulate Matter (PM) and just remain suspended in the air, for hours, sometimes even for days. Air with more than prescribed quantity of Particulate Matter is hazardous to breathe and may cause serious respiratory ailments.

Natural Causes of Pollution

There are also some natural causes of pollution, which cause huge damage to the environment. Though, they are not consistent in appearance, yet, they cause considerable damage to the environment.

Some of the natural causes of the environmental pollution are volcanoes, forest fires, dust storms. During the volcanic eruption and forest fires large quantities of toxic gases are released causing damage to the environment.

There is a need to immediately limit the effects of pollution as it is destroying the environment with every passing minute. Not only the pollution is contaminating our natural resources it also threatens the very existence of life on earth.

It is a collective responsibility of everyone to take necessary action towards preventing any further damage to the environment. This could be achieved by decreasing waste and introducing new and effective waste disposal and management techniques.

How Air Pollution Damages the Brain

The new science of "exposomics" shows how air pollution contributes to Alzheimer’s, Parkinson’s, bipolar disorder and other brain diseases

By 1992, burgeoning population, choking traffic, and explosive industrial growth in Mexico City had caused the United Nations to label it the most polluted urban area in the world. The problem was intensified because the high-altitude metropolis sat in a valley trapping that atmospheric filth in a perpetual toxic haze. Over the next few years, the impact could be seen not just in the blanket of smog overhead but in the city’s dogs, who had become so disoriented that some of them could no longer recognize their human families. In a series of elegant studies, the neuropathologist Lilian Calderón-Garcidueñas compared the brains of canines and children from “Makesicko City,” as the capital had been dubbed, to those from less polluted areas. What she found was terrifying: Exposure to air pollution in childhood decreases brain volume and heightens risk of several dreaded brain diseases, including Parkinson’s and Alzheimer’s, as an adult.

Calderón-Garcidueñas, today head of the Environmental Neuroprevention Laboratory at the University of Montana, points out that the damaged brains she documented through neuroimaging in young dogs and humans aren’t just significant in later years; they play out in impaired memory and lower intelligence scores throughout life. Other studies have found that air pollution exposure later in childhood alters neural circuitry throughout the brain, potentially affecting executive function, including abilities like decision-making and focus, and raising the risk of psychiatric disorders.

The stakes for all of us are enormous. In places like China, India, and the rest of the global south, air pollution, both indoor and outdoor, has steadily soared over the course of decades. According to the United Nations Foundation , “nearly half of the world’s population breathes toxic air each day, including more than 90 percent of children.” Some 2.3 billion people worldwide rely on solid fuels and open fires for cooking, the Foundation adds, making the problem far worse. The World Health Organization calculates about 3 million premature deaths, mostly in women and children, result from air pollution created by such cooking each year.

In the United States, meanwhile, average air pollution levels have decreased significantly since the passage of the Clean Air Act in 1970. But the key word is average . Millions of Americans are still breathing outdoor air loaded with inflammation-triggering ozone and fine particulate matter. These particles, known as PM 2.5 (particles less than 2.5 micrometers in diameter), can affect the lungs and heart and are strongly associated with brain damage . Wildfires—like the ones that raged across Canada this past summer—are a major contributor of PM 2.5 . A recent study showed that pesticides, paints, cleaners, and other personal care products are another major—and under-recognized—source of PM 2.5 and can raise the risk for numerous health problems, including brain-damaging strokes.

Untangling the relationship between air pollution and the brain is complex. In the modern industrial world, we are all exposed to literally thousands of contaminants. And not every person exposed to a given pollutant will develop the same set of symptoms, impairments, or diseases—in part because of their genes, and in part because each exposure may occur at a different point in development or impact a different area of the body or brain. What’s more, social disparities are at play: Poorer populations almost always live closer to factories, toxins, and pollutants.

The effort to figure it out and intervene has sparked a new field of study: exposomics, the science of environmental exposures and their effects on health, disease, and development. Exposomics draws on enormous datasets about the distribution of environmental toxins, genetic and cellular responses, and human behavioral patterns. There is a huge amount of information to parse, so researchers in the field are turning to another emerging science, artificial intelligence, to make sense of it all.

“Anything from our external environment—the air we breathe, food we eat, the water we drink, the emotional stress that we face every day—all of that gets translated into our biology,” says Rosalind Wright , professor of pediatrics and co-director of the Institute for Exposomic Research at the Icahn School of Medicine at Mount Sinai in New York. “All these things plus genes themselves explain the patterns of risk we see.” When an exposure is constant and cumulative, or when it overwhelms our ability to adapt, or “when you’re a fetus in utero, when you’re an infant or in early childhood or in a critical period of growth,” it can have a particularly powerful effect on lifelong cognitive clarity and brain health.

Neuroscientist Megan Herting at the University of Southern California (USC) has been studying the impact of air pollution on the developing brain. “Over the past few years, we have found that higher levels of PM 2.5 exposure are linked to a number of differences in the shape, neural architecture, and functional organization of the developing brain, including altered patterns of cortical thickness and differences in the microstructure of gray and white matter,” she says. On the basis of neuroimaging of exposed youngsters, Herting and fellow researchers suspect the widespread differences in brain structure and function linked with air pollution may be early biomarkers for cognitive and emotional problems emerging later in life.

That suspicion gains support from an international meta-analysis (a study of other studies) published in 2023 that correlated exposure to air pollution during critical periods of brain development in childhood and adolescence to risk of depression and suicidal behavior. The imaging parts of the studies showed changes in brain structure, including neurocircuitry potentially involved in movement disorders like Parkinson’s, and white matter of the prefrontal lobes, responsible for executive decision-making, attention, and self-control.

In a 2023 study , Herting and colleagues tracked children transitioning into adolescence, when brains are in a sensitive period of development and thus especially vulnerable to long-term damage from toxins. Among brain regions developing during this period is the prefrontal cortex, which helps with cognitive control, self-regulation, decision-making, attention, and problem-solving, Herting says. “Your emotional reward systems are also still being refined,” she adds.

Looking at scan data from more than 9,000 youngsters exposed to air pollution between ages 9 and 10 and following them over the next couple of years, the researchers found changes in connectivity between brain regions, with some regions having fewer connections and others having more connections than normal. Herting explains that these structural and functional connections allow us to function in our daily lives, but how or even whether the changes in circuitry have an impact, researchers do not yet know.

The specific pollutants involved in the atypical brain circuits appear to be nitrogen dioxide, ozone, and PM 2.5 —the small particles that worry many researchers the most. Herting explains: Limits set on fine particulate matter are stricter in the United States than in most other countries but still inadequate. The U.S. Environmental Protection Agency currently limits annual average levels of the pollutant to 12 micrograms per cubic meter and permits daily spikes of up to 35 micrograms per cubic meter. Health organizations, on the other hand, have called for the agency to lower levels to 8 micrograms and 25 micrograms per cubic meter, respectively. Thus, even though it may be “safe” by EPA standards, “air quality across America is contributing to changes in brain networks during critical periods of childhood,” Herting says. And that may augur “increased risk for cognitive and emotional problems later in life.” She plans to follow her group of young people into adulthood, when advances in science and the passage of time should reveal more about the effect of air pollution exposure during adolescence.

Other research shows that air pollution increases risk of psychiatric disorder as years go by. In work based on large datasets in the United States and Denmark, University of Chicago computational biologist Andrey Rzhetsky and colleagues found that bad air quality was associated with increased rates of bipolar disorder and depression in both countries, especially when exposure occurs early in life. Rzhetsky and his team used two major sources: in Denmark, the National Health Registry, which contains health data on every citizen from cradle to grave; and in the United States, insurance claims with medical history plus details such as county of residence, age, sex, and importantly, linkages to family—specifics that helped reveal genetic predisposition to develop a psychiatric condition during the first 10 years of life.

“It's possible that the same environment will cause disease in one person but not in another because of predisposing genetic variants that are different in different people,” Rzhetsky says. “The different genetic predisposition, that’s one part of the puzzle. Another part is varying environment.”

Indeed, these complex diseases are spreading much faster than genetics alone seems to explain. “We definitely don’t know for sure which pollutant is causal. We can’t really pinpoint a smoking gun,” Rzhetsky says. But one pesky culprit continues to prove statistically significant: “It looks like PM 2.5 is one of those strong signals.” To figure it out specifically, we’ll need much more data, and exposomics will play a vital role.

"This is a wake-up call,” Frances Jensen told her fellow physicians at the American Neurological Society’s symposium on Neurologic Dark Matter in October 2022. The meeting was an exploration of the exposome –the sum of external factors that a person is exposed to during a lifetime— driving neurodegenerative disease. It was focused in no small part on air pollution. Jensen, a University of Pennsylvania neurologist and president of the American Neurological Association, argued that researchers need to pay more attention to contaminants because the sharp rise in the number of Parkinson’s diagnoses cannot be explained by the aging population alone. “Environmental exposures are lurking in the background, and they’re rising,” she said.

Parkinson’s disease is already the second-most common neurodegenerative disease after Alzheimer’s. Symptoms, which can include uncontrolled movements, difficulty with balance, and memory problems, generally develop in people age 60 and older , but they can occur, though rarely, in people as young as 20. Could something in the air explain the increasing worldwide prevalence of Parkinson’s? Researchers have not identified one specific cause, but they know Parkinson’s symptoms result from degeneration of nerve cells in the substantia nigra, the part of the brain that produces dopamine and other signal-transmitting chemicals necessary for movement and coordination.

A host of air pollution suspects are now thought to play a role in the loss of dopamine-producing cells, according to Emory University environmental health scientist W. Michael Caudle , who uses mass spectrometry to identify chemicals in our bodies. One suspect he’s looking at are lipopolysaccharides, compounds often found in air pollution and bacterial toxins. Although lipopolysaccharides cannot directly enter the brain, they inflame the liver. The liver then releases inflammatory molecules into the bloodstream, which interact with blood vessels in the blood-barrier. “Then the inflammatory response in the brain leads to loss of dopamine neurons, like that seen in Parkinson’s disease,” Caudle says.

More evidence comes from neuroepidemiologist Brittany Krzyzanowski , based at the Barrow Neurological Institute in Phoenix. Krzyzanowski had an “aha!” moment when she saw a map highlighting the high risk of Parkinson’s disease in the Mississippi–Ohio River Valley, including areas of Tennessee and Kentucky. At first she wondered whether the Parkinson’s hotspot was due to pesticide use in the region. But then it hit her: The area also had a network of high-density roads, suggesting that air pollution could be involved. “The pollution in these areas may contain more combustion particles from traffic and heavy metals from manufacturing, which have been linked to cell death in the part of the brain involved in Parkinson’s disease,” she said.

In a study published in Neurology in October 2023, Krzyzanowski and colleagues, using sophisticated geospatial analytic techniques, went on to show that those with median levels of air pollution have a 56 percent greater risk of developing Parkinson’s disease compared to those living in regions with the lowest level of air pollution. Along with the Mississippi-Ohio River Valley, other hotspots included central North Dakota, parts of Texas, Kansas, eastern Michigan, and the tip of Florida. People living in the western half of the U.S. are at a reduced risk of developing Parkinson’s disease compared with the rest of the nation.

As to the hotspot in the Mississippi-Ohio River Valley, Parkinson’s there is 25% higher than in areas with the lowest air particulate matter. Aside from that, Krzyzanowski and her research team noted something especially odd: Frequency of the disease rose with the level of pollution, but then it plateaued even as air pollution continued to soar. One reason could be that other air pollution-linked diseases, including Alzheimer’s, are masking the emergence of Parkinson’s; another reason could be an unusual form of PM 2.5 . “Regional differences in Parkinson’s disease might reflect regional differences in the composition of the particulate matter, and some areas may have particulate matter containing more toxic components compared to other areas,” Krzyzanowsk says. Tapping the tenets of exposomics, she expects to explore these issues in the months and years ahead.

The hunt is on for the connections between environmental factors and Alzheimer’s as well. USC neurogerontologist Caleb Finch has spent years studying dementia, especially Alzheimer’s disease, which affects more than six million Americans. As with Parkinson’s, Alzheimer’s numbers are rising in the United State and much of the world. Degenerative changes in neurons become increasingly frequent after the age of 60, yet half of the people who make it to 100 will not get dementia. Many factors could explain those discrepancies. Air pollution may be an important one, Finch says.

Researchers like Finch and his USC colleague Jiu-Chiuan Chen are joining forces to explore the connections between environmental neurotoxins and decline in brain health. It’s a challenging project, since air pollution levels and specific pollutants vary on fine scales and can change from hour to hour in many areas of the globe. On the basis of brain scans of hundreds of people over a range of geographic areas, this much we know: “People living in areas of high levels of air pollution and who have been studied on three continents showed accelerated arterial disease, heart attacks, and strokes, and faster cognitive decline,” Finch says.

Not everyone reacts the same way when exposed to pollutants, of course. Greatest risk for Alzheimer’s seems to hit people who have a genetic variant known as apolipoprotein E (APOE4), which is involved in making proteins that help carry cholesterol and other types of fat in the bloodstream. About 25 percent of people have one copy of that gene, and 2 to 3 percent carry two copies. But inheriting the gene alone doesn’t determine a person’s Alzheimer’s risk. Environmental exposures count too.

A recent study by Chen, Finch, and colleagues published in the Journal of Alzheimer’s Disease looked at associations between air pollution exposure and early signs of Alzheimer’s in 1,100 men, all around age 56 when the study began. By age 68, test subjects with high PM 2.5 exposures had the worst scores in verbal fluency. People exposed to high levels of nitrogen dioxide (NO 2 ) air pollution were also linked to worsened episodic memory. The men who had APOE4 genes had the worst scores in executive function. The evidence indicates that the process by which air pollution interacts with genetic risk to cause Alzheimer’s in later life may begin in the middle years, at least for men.

A separate USC study of more than 2,000 women found that when air quality improved, cognitive decline in older women slowed. When exposure to pollutants like PM 2.5 and NO 2 dropped by a few micrograms per cubic foot a year over the course of six years, the women in the study tested as being a year or so younger than their real age. This suggests that when exposure air pollution is lowered, dementia risk can go down.

In parallel, an international study by the Lancet Commission concluded that the risk of dementia, including Alzheimer’s, can be lowered by modifying or avoiding 12 risk factors: hypertension, hearing impairment, smoking, obesity, depression, low social contact, low level of education, physical inactivity, diabetes, excessive alcohol consumption, traumatic brain injury—and air pollution. Together, the 12 modifiable risk factors account for around 40 percent of worldwide dementias, which theoretically could be prevented or delayed.

In light of all this, Finch and Duke University social scientist Alexander Kulminski have proposed the “ Alzheimer’s disease exposome ” to assess environmental factors that interact with genes to cause dementia. Where medicines have failed, exposomics just might help. Studies of Swedish twins show that half of individual differences in Alzheimer’s risk may be environmental, and thus modifiable; and while vast sums of research funding have been poured into the genetic roots of the disease, it could be that altering the exposome would provide a better preventive than all the ongoing drug trials to date. Environmental toxins broadly disrupt cell repair and protective mechanisms in the brain, the researchers point out. And factors like obesity and stress contribute to chronic inflammation, which likely damages neurons’ ability to function and communicate. The research framework of the Alzheimer's disease exposome offers a comprehensive, systematic approach to the environmental underpinnings of Alzheimer's risk over individuals’ lifespans—from the time they are pre-fertilized gametes to life as a fetus in the womb to childhood and beyond.

For three decades, Rosalind Wright at Mount Sinai has wanted to trace critical problems in neurodevelopment and neurodegeneration to pollutants—from highway emissions to heavy metals to specific household chemicals and a host of other factors—but the mass of data has been overwhelming. With the advent of artificial intelligence (AI) and sophisticated neuroimaging technology, high-precision research using vast genomic databanks is finally possible. “I knew we needed to ask these kinds of questions, but I didn't have the tools to do it. Now we do and it’s very exciting,” Wright says.

Using machine learning—an AI approach to data analysis—Wright looks at giant datasets that include the precise location of an individual’s residence as well as the myriad of pollutants he or she encounters. “It's no different fundamentally from other statistical models we use,” she says. “It’s just that this one has been developed to be able to take in bigger and bigger data, more and more types of exposures.” The resulting data breakdown should tell us which factors drive which types of risk for which people. That information will help people know where they should target their efforts to reduce exposures to risky pollutants, and ultimately how to lower risk of impairment and disease, brain or otherwise.

The tools used by Wright and her colleagues are being trained on diseases like Alzheimer’s. If you put genes and the environment together, “you start to see who might be at higher risk and also what underlying mechanisms might be driving it in different ways in different populations,” Wright says. The exposome could also explains more subtle cognitive effects of pollution that may emerge over long periods, such as harms to attention, intelligence, and performance.

To address environmental brain risks, it’s important to know which pollutants are present—another target of exposomic research. In the United States, the EPA has placed stationary environmental monitors all over our major cities, conducting daily measurements of small particulates from traffic and industry, along with secondary chemicals that emerge as a result. There are also thousands of satellites all over the globe calibrating heat waves that can alter how the pollutants react with each other.

Pioneers like Wright are just starting to chart the terrain of environmental exposures that affect the brain. “As we measure more and more of the exposome, we may be able to tailor prevention and intervention strategies. New weapons include a silicone bracelet that we have in the laboratory. You wear it and it will tell us what pollutants you are exposed to,” Wright says. She also is exploring more ways to collect data on the toxins people have already encountered: “With a single strand of hair, we can tell you what you’ve been exposed to. Hair grows about a centimeter a month, so if we get a hair from a pregnant woman and she has nine centimeters of hair, we can go back a full nine months, over the entire life of the fetus. Or we can create a life-long exposome history when a child loses a tooth at age six.”

“We're designed to be pretty resilient,” Wright adds. The problem comes when the exposures are chronic and accumulative and overwhelm our ability to adapt. We’re not going to fix everything, “but if I know more about myself than before, that empowers me to think, ‘I’m optimizing the balance, and I’m intervening as best I can.’ ”

Noise Pollution: Effects, Causes, and Potential Solutions Essay

Introduction, effects of noise pollution, causes of noise pollution, potential solutions, works cited.

Some people may frown upon it, while others might nod their heads with their whole-hearted smile on their faces – no matter which category you belong to, as a person, especially as a person who must live in a neighborhood, the quality of the neighborhood has always been an important issue to be concerned about when you are looking for a place to live. For most people, the quality of the neighborhood is at the center of attention even more than the quality of the living spaces. As much as a good neighborhood can positively affect our mental and physical health and improve the quality of our lives, a bad neighborhood can increase anxiety among neighbors and can decrease their lives’ efficiency. Although there exist lots of problems that need to be solved in every neighborhood, noise pollution, no matter whether this noise is made by your neighbors or the surrounding environment, is with no doubt the most important issue in almost all neighborhoods. First, it is essential to investigate the reasons why noise is an important issue in almost every neighborhood and then explore the main contributing causes of the noise problem.

The first and also foremost reason why noise is an important issue in neighborhoods lies in the inevitable fact that noise pollution can have negative effects on our physical health. Living in a noisy area can affect the quality of people’s sleep, daily activities, and even general physical health factors. According to the International Program on Chemical Safety, “an adverse effect of noise is defined as a change in the morphology and physiology of organism that results in an impairment of functional capacity, or an impairment of capacity to compensate for additional stress or increases the susceptibility of the organism to harmful effects of other environmental influences” (Siano). Environmental noise exposure is responsible for a range of health effects, including increased risk of ischemic heart disease as well as sleep disturbance, cognitive impairment among children, annoyance, stress-related mental health risks, and tinnitus. This noise pollution becomes more important when we look at the noise level in residential neighbors where people spend most of their time.

For instance, “the health risks caused by noise pollution in high income European countries account for a loss of 1-1.6 million disability adjusted life years (DALYs) – a standard measure of healthy years of life lost to illness, disability, or early death” (Siano). Also, according to the World Health Organization (WHO), “noise pollution is one of the most dangerous environmental threats to health” (IBERDROLA). Moreover, according to the European Environmental Agency (EEA), “noise is responsible for 16,600 premature deaths and more than 72,000 hospitalizations every year in Europe alone” (IBERDROLA). Not only noise pollution can cause health issues for human, but it has a devastating impact on animals as well. According to the National Park Services (NPS) in the United States, “noise pollution has an enormous environmental impact and does serious damages to wildlife” (IBERDROLA). Most of the experts say that noise pollution can interfere with breeding cycles and rearing, and it is even hastening the extinction of some animal species. Therefore, noise pollution can not only affect mental health, but it can also affect our physical health.

Another reason, which is as important as the preceding one, if not more, is that noisy neighborhoods can substantively affect the efficiency of people’s work and their daily life activities. In the present day, the amount of noise in a living neighborhood becomes even more important since most of the people are forced to work from home due to the rules that companies made for their employees during the pandemic. To elucidate, the noisier a neighborhood is, the harder it becomes to concentrate on the activities that neighbors do, especially for the employees who work from home. The lower efficiency of activities will result in the lower efficient people in society. Moreover, the lower efficient people in society become more anxious and depressed as they see their activity outputs. Based on the report of the IKO Community Management survey, “48 percent of all survey takers said noise is number one complaint among the people who live in a neighborhood in large cities, whether this noise is from raucous late-night parties or opposite sleep schedules that result in one neighbor waking up the other” (IKO Community Management). As an illustration of the effect of noise pollution in the community that I live in, we always see struggling between the people who work at home during the day and the teenagers who play loud music and have parties at their apartment. Once, our neighbor, Larry, who is a programmer, complained to the community management office about George, a young boy who invites his friend to their apartment any time of the day to play loud music and laugh loudly. Larry told me, “it is important that people like George be aware of the rights of other people who live in the same area with them” (Pileggi). Therefore, noise pollution can affect our mental concentration level and efficiency at work.

After understanding the effects of noise on the neighbors, it is highly essential to explore the main contributing causes of noise. In comparison with ancient times when there were not many sources causing noise, these days, multiple different causes of noise exist. These causes can range from natural environment causes to human-generated causes. Although nature can make noises caused by animals and natural effects, human-generated noises are usually more dangerous and annoying. From a personal perspective, the most important three causes of noise that are also generated by humans are traffic and transportation noise, construction sites, and nightlife, though noise can come from a variety of other places as well.

Among these three sources of noise, I believe that the first and the most important cause of the noise is traffic and transportation noise. Without a doubt, we all live in homes that are close to at least one street or one alley. Living close to streets or alleys will cause being affected by the noise that is generated by passing cars. Moreover, some homes are close to bus stations or railroads, which means that people who live in these apartments suffer from louder noises generated by these huge public transportation facilities. According to the IBERDROLA, “a car horn produces 90 dB of noise and a bus produces 100 dB of noise.” On the basis of the World Health Organization’s (WHO) definition of noise, if we consider noise above 65 dB as noise pollution, this generated transportation noise can have a negative effect on our health. To be precise, noise becomes harmful when it exceeds 75 dB, and it will become painful if it is above 120 dB.

According to WHO, “it is recommended that noise levels to be kept below 65 dB during the day and 30 dB during nighttime” (WHO). A worse case is living close to the rail yard, as neighbors of the rail yard suffer from a higher level of noise pollution. Based on the interview that has been done about pros and cons of living close to a major rail yard, the interviewees felt that despite the fact that “the rail yard had a positive reputation and was highly valued for the jobs and economic growth it provides, it was also perceived, however, as a major contributor to the surrounding air quality as well as the noise pollution” (Spencer-Hwang). Several participants believed that “living in such close proximity to the rail yard had caused ailments in family, friends, and neighbors, as well as themselves” (Spencer-Hwang). Moreover, transportation noise can cause health-related issues, as previously discussed ones. According to the National Institute of Environmental Health Sciences, Clark et al. 2017 found “an increasing risk of diabetes with increasing exposure to transportation noise, but not with increasing exposure to traffic-related air pollutions.” In their study, noise pollution was independently associated with the incidence of diabetes in adult residents of metropolitan Vancouver, British Columbia (Clark). Therefore, transportation noise is not only unacceptable for most of the neighbors, but it is also risky for our health.

As the second source of noise, which is not as common as the first resource, we can consider construction. You may have experienced construction noise, even in the early morning, that affected your sleep quality and caused you to wake up because of this construction noise. Although not all the neighbors are close to construction zones and construction noise is not a common cause of the noise, building, car park construction, and road and pavement resurfacing generate an even greater amount of noise, with noise level even higher than transportation. As an example, according to IBERDROLA, “a pneumatic drill produces 110 dB noise,” which is higher than the noise that is generated by car horns and buses. Whether self-inflicted or common, everyday living noise can cause temporary or permanent deafness. When one is around noise for long periods of time, the risk of deafness is increased. “Construction noise has become the second most serious acoustic pollution in many cities, which could cause significant health damage and social costs. In addition, housing renovation and construction noise, which has rarely been investigated before, is a significant covariate of a wide range of mental health symptoms” (Ma). Specifically, as big cities are experiencing rapid urbanization processes, there are numerous ongoing construction projects that have led to an increase in environmental complaints, and construction noise has become a serious problem in the majority of big cities. For example, among people at higher risk of health problems caused by construction noise, “construction workers are at increased risk for being hearing impaired” (Cunningham). Therefore, construction as the second cause of the noise can result in serious mental and physical health problems as well.

The third cause of the noise is related to the nightlife. Humans have been created to live in social groups naturally. That is why all of us spend most of our time and socialize with our friends and family. However, sometimes this socialization can affect other people, especially if gatherings and socialization are generating loud noise and we are not paying attention to the others living close to us. Especially, a person who lives close to bars, restaurants, and clubs will feel noise that is generated by socialization and gatherings much more. According to IBERDROLA, “bars, restaurants, and terraces that spill outside when the weather is good can produce more than 100 dB noise. This includes noise from pubs and clubs”. According to Peplow et al., “sustained exposure to noise in areas close to public places also has been correlated with cognitive impairment and behavioral problems in children, as well as the more obvious hearing damage and sleep deprivation”. The European Environment Agency (EAA) has blamed “900 thousand cases of high blood pressure (hypertension), 43 thousand hospital admissions and 10 thousand cases of premature deaths a year in Europe on noise”. As a real example, I talked to our neighbor, Mr. Smith, about the reason of his high blood pressure. He told me that “the doctor told me that the main reason of my high blood pressure is living in the busiest part of the Santa Monica area. To decrease my blood pressure, the doctor recommended my wife and me to move to a suburb area”. Therefore, living close to the places that are designed specifically for nightlife can increase the risk of being affected by noise pollution.

Having scrutinized the issue, although people’s ideas vary on different points of the spectrum regarding the noise pollution issue in a neighborhood, I strongly believe that noise pollution is the first and most important issue that should be solved because of its destructive effects on mental and physical health. Although there exist many causes for noise pollution, I believe that transportation noise as the first and the most important cause, construction, and night life are the three most important causes of noise pollution. Hence, I think the explanation that I have provided above in favor of the destructive effects and the main causes of noise pollution are much stronger.

After finding out that all types of noise in living areas have an immeasurably negative impact on people’s health, work efficiency, and daily life activities, I see that the potential solutions to the problem of noise pollution are to either control its level by the government or allow people to use various techniques in order to decrease the level of noise independently. However, as the government cannot apply effective measures to all areas where people live, citizens’ individual measures will be more efficient.

It goes without saying that noise pollution has already become an international problem as almost all big cities across the globe face it. In general, the most common measures aimed to reduce the level of noise include the limitation of noisy leisure activities, especially at night, the use of bicycles instead of cars, environmental education, and the insulation of houses with noise-absorbing materials (IBERDROLA). As a matter of fact, governmental policies may ensure noise control and correct control management by area protection and sustainable building construction. For instance, the United States Environmental Protection Agency established the Office of Noise Abatement and Control (ONAC) under the Clean Air Act to study noise pollution and investigate its impact on the public health and people’s welfare (EPA). Since 1972, ONAC had been operating “to coordinate federal monitoring and regulation of noise at its source and facilitate informed policy-making at the state and local levels” (APHA).

The Office’s scope was expanded in 1978 by Congress that passed the Quiet Communities Act, including research funding and public health education dedicated to noise pollution (APHA). In general, ONAC created model noise ordinances, issued standards for local governments, and promulgated guidance documents in accordance with recommended or already existing exposure levels. In general, the governmental response includes appropriate planning policies and the introduction of the standards of sustainable construction in order to reduce the level of noise from the external environment in living buildings. In addition, the level of noise in residential buildings should be reduced as well according to the Building Regulations Approved Document E (Simonsen).

At the same time, governmental control cannot be regarded as a highly efficient measure. First of all, in 1981, the Administration decided that all issues related to noise pollution should be monitored by state and local governments (EPA). That is why, due to funding limitations, ONAC was closed. As a result, since 1986, no standards, regulations, or rules have been promulgated to limit sources of noise in electronics, appliances, industry, recreational items, or machinery (APHA). In addition, contemporary measures are not fully efficient due to their limited scope. In other words, only such territories as city parks, areas of natural interest, and new parts of the city may be protected (IBERDROLA). As a result, the majority of districts, especially old ones with established infrastructure, will be left without any changes. In addition, the idea of the construction of houses with the use of noise-absorbing materials is relevant only for new buildings. Thus, old buildings will be unprotected, and the level of noise in them will remain the same. Consequently, people who live in old districts with established infrastructure will suffer from the same levels of noise until they solve this issue by themselves.

That is why private measures that aim to reduce noise pollution for individuals and families who apply them are more efficient in comparison with policies that cannot affect all people. In other words, citizens may apply multiple useful, cost-effective techniques in order to reduce noise pollution in their apartments by themselves. The measures include the installation of acoustic wall panels, window shutters, or noise-blocking doors, placing furniture strategically, and turning off electrical appliances that constantly produce noise as well (JosTec). Noise cancelling headphones or earplugs may serve as a short-term solution in the case of construction work. Due to them, people will have a good sleep at night. Moreover, such design elements as wall hangings and carpets or rugs help reduce the level of noise. In addition, planting bushes and trees around the house by community members will reduce noise pollution and improve air quality as well. All these techniques may be defined as an excellent alternative for all people living in big cities, especially for those ones who cannot afford to move to another area protected from noise pollution.
