Pollution is defined as introducing harmful substances (solid, liquid, or gas) or any form of energy (light, heat, sound, or radioactivity) into the environment. The harmful elements that damage air, water, and land quality and cause pollution are called pollutants.
Pollution is primarily human-made, but nature can have an adverse effect also sometimes acts as a source of pollution.
The three major types of environmental pollution are air, water, and soil. Besides these three main types, there are noise, light, thermal, and radioactive pollutions.
The air in our atmosphere has a roughly stable chemical composition consisting of nitrogen, oxygen, argon, carbon dioxide, and trace amounts of other gases. Any change in the air composition due to the addition of unwanted gases such as sulfur dioxide, carbon monoxide, and nitrogen oxides, chemicals, particulate matter, and biological molecules is called air pollution.
Among all other types of pollution, air pollution is found to have the most diverse impact on Earth.
Sources/Causes
Air pollution can happen from both human-made (anthropogenic) and natural sources. Some of the significant sources of air pollution are given below:
Water pollution occurs when toxic pollutants and particulate matter are introduced into water bodies such as oceans, rivers, lakes, ponds, and aquifers, making them impure and toxic. These contaminants are primarily generated by human activities and sometimes by natural disasters.
Among all other types of pollution, water pollution is found to have the maximum adverse consequences on the ecosystem.
Sometimes called land pollution, it refers to the degradation of land quality due to unwanted chemicals and other factors in the soil. Such chemicals change the soilâs chemical and biological properties, thus affecting plant growth. Green plants, being the primary producer, absorb those pollutants, which are then passed through the food chain, affecting the whole ecosystem.
Soil pollution can seep into groundwater or run off to the nearest streams and lakes, creating a vicious pollution cycle.
1. Light Pollution
Light pollution refers to the excessive amount of light in the night sky. It occurs due to excessive, misdirected, and inefficient lighting systems by humans. It is also called photo pollution that disrupts the ecosystem by reducing the distinction between night and day.
Although light pollution seems to have a lesser impact than any other form, it is expected to have consequences similar to air or water pollution.
2. Noise Pollution
It refers to the excessive amount of sound in the surroundings disrupting the natural balance. The acceptable amount of sound is about 60 to 65 decibels, which is the same as our everyday conversation.
Sound levels above 85 decibels are harmful depending on the duration of exposure. Noise above 140 decibels can cause permanent hearing loss. Also, the duration of exposure to the sound is found to have negative health impacts.
Apart from the types of pollution discussed, there are other forms of pollution called thermal or heat pollution and radioactive pollution .
Thermal pollution is caused due to excessive heat in the environment released from industrial power plants, deforestation, urban sprawl, and air pollution. It increases the Earthâs atmosphere causing drastic climate change and extinction of wildlife. In contrast, radioactive pollution results from accidental leakage from nuclear power plants and improper disposal of nuclear wastes. It can cause massive, long-lasting impacts such as cancer, infertility, blindness, and congenital disabilities.

Pollution control.
Does pollution cause climate change, how can we reduce pollution.
Our editors will review what youâve submitted and determine whether to revise the article.
Pollution occurs when an amount of any substance or any form of energy is put into the environment at a rate faster than it can be dispersed or safely stored. The term pollution can refer to both artificial and natural materials that are created, consumed, and discarded in an unsustainable manner.
Air pollution , water pollution , and land pollution are three major forms of environmental pollution. Pollution can also refer to excessive human activity, such as light and noise pollution , or to specific pollutants such as plastic or radioactive material. Learn more in this infographic.
Air pollution is the main cause of climate change . Human activities such as burning fossil fuels and mass deforestation lead to the increase of carbon dioxide in the atmosphere , which traps heat inside the atmosphere through a process called the greenhouse effect . This impacts climate patterns and sea levels around the world.
Pollution can be reduced through processes such as recycling and the proper treatment of water and toxic waste . The reduction of corporate fossil fuel extraction is another way to counter air pollution . According to the Carbon Majors Report prepared by the Carbon Disclosure Project in 2017, more than 70 percent of greenhouse gas emissions comes from only 100 companies.
Air pollution is estimated to kill 7 million people every year. Radioactive and toxic waste in water can cause many diseases, including fatal conditions such as typhoid fever and cholera . Consumption of contaminated water causes approximately 485,000 deaths every year.
pollution , the addition of any substance ( solid , liquid , or gas ) or any form of energy (such as heat , sound, or radioactivity ) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are air pollution , water pollution , and land pollution . Modern society is also concerned about specific types of pollutants, such as noise pollution , light pollution , and plastic pollution . Pollution of all kinds can have negative effects on the environment and wildlife and often impacts human health and well-being.
Although environmental pollution can be caused by natural events such as forest fires and active volcanoes , use of the word pollution generally implies that the contaminants have an anthropogenic sourceâthat is, a source created by human activities. Pollution has accompanied humankind ever since groups of people first congregated and remained for a long time in any one place. Indeed, ancient human settlements are frequently recognized by their wastesâ shell mounds and rubble heaps, for instance. Pollution was not a serious problem as long as there was enough space available for each individual or group. However, with the establishment of permanent settlements by great numbers of people, pollution became a problem, and it has remained one ever since.
Cities of ancient times were often noxious places, fouled by human wastes and debris. Beginning about 1000 ce , the use of coal for fuel caused considerable air pollution, and the conversion of coal to coke for iron smelting beginning in the 17th century exacerbated the problem. In Europe, from the Middle Ages well into the early modern era, unsanitary urban conditions favoured the outbreak of population-decimating epidemics of disease, from plague to cholera and typhoid fever . Through the 19th century, water and air pollution and the accumulation of solid wastes were largely problems of congested urban areas. But, with the rapid spread of industrialization and the growth of the human population to unprecedented levels, pollution became a universal problem.
By the middle of the 20th century, an awareness of the need to protect air, water, and land environments from pollution had developed among the general public. In particular, the publication in 1962 of Rachel Carson âs book Silent Spring focused attention on environmental damage caused by improper use of pesticides such as DDT and other persistent chemicals that accumulate in the food chain and disrupt the natural balance of ecosystems on a wide scale. In response, major pieces of environmental legislation, such as the Clean Air Act (1970) and the Clean Water Act (1972; United States), were passed in many countries to control and mitigate environmental pollution.
Giving voice to the growing conviction of most of the scientific community about the reality of anthropogenic global warming , the Intergovernmental Panel on Climate Change (IPCC) was formed in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Program (UNEP) to help address greenhouse gas emissions. An IPCC special report produced in 2018 noted that human beings and human activities have been responsible for a worldwide average temperature increase between 0.8 and 1.2 °C (1.4 and 2.2 °F) since preindustrial times, and most of the warming over the second half of the 20th century could be attributed to human activities, particularly the burning of fossil fuels .
The presence of environmental pollution raises the issue of pollution control . Great efforts are made to limit the release of harmful substances into the environment through air pollution control , wastewater treatment , solid-waste management , hazardous-waste management , and recycling . Unfortunately, attempts at pollution control are often surpassed by the scale of the problem, especially in less-developed countries . Noxious levels of air pollution are common in many large cities, where particulates and gases from transportation, heating, and manufacturing accumulate and linger. The problem of plastic pollution on land and in the oceans has only grown as the use of single-use plastics has burgeoned worldwide. In addition, greenhouse gas emissions, such as methane and carbon dioxide , continue to drive global warming and pose a great threat to biodiversity and public health .

One of the biggest risks to life as we know it is environmental degradation. The water we drink, the air we breathe, and the ecosystems on which we depend are all impacted by pollution. People, animals, and plants will decline if pollution levels continue to rise since they won’t be able to adapt to a significantly altered environment. Are you struggling to write an essay on environmental pollution? If the answer is yes, then this blog will help you get some ideas to write an effective essay. Keep reading further to know more!

The phenomenon of undesirable changes in the surroundings that are harmful to animals and plants, and leads to environmental degradation is known as environmental pollution. These changes can occur because of the solid, liquid or gaseous pollutants. For example, DDT, plastic, and heavy materials take more time to degrade and are known as notable pollutants. For the determination of risk assessment of public health, concentration of pollutants is measured.
The presence of contaminants in the environment is referred to as pollution. Gases like Carbon Dioxide (CO2) and Carbon Monoxide (CO), among others; solid pollutants like plastic, sewage, etc.; and chemicals like fertilisers, as well as those produced as byproducts in manufacturing, transportation, etc., are a few examples of polluting substances.
The immediate result of pollution is that it makes the world’s natural resources useless or toxic to use, as well as leads to the extinction of species and ecological imbalance. To stop more harm from occurring to the earth and its inhabitants due to environmental pollution, it is imperative to take proactive precautions.

When undesired elements, or pollutants, are present in the environment, it is said to be polluted. The environment is severely harmed by pollution, which poses a direct threat to it. Although the world has begun to understand the importance of addressing pollution if the planet and its biodiversity are to be conserved there is still a long way to go.
Everything that makes up the environment, including the air, water bodies, flora, and wildlife, is impacted by pollution in one way or another. There are four main types of pollution – Air Pollution, Water Pollution, Noise Pollution and Soil or Land Pollution . Additionally, pollution contributes to global issues including acid rain, global warming, and greenhouse gas consequences. A rise in the planet’s average surface temperature is referred to as global warming, and it causes starvation, floods, and droughts.
Environmental pollution has a wide-ranging impact. In addition to the current effects of pollution, a lack of effective pollution prevention measures also imperils the future of various species. The pollution is causing harm at a far faster rate than it can be healed. Reversing the environmental harm we have caused could take generations, and even then, it won’t be simple. It will require tight discipline and commitment to stop pollution.
The best ways feasible are being used by various nations to respond to these catastrophes. More efforts are being launched to raise public awareness about the dangers of pollution and the importance of preserving our ecosystem. Greener lifestyles are gaining popularity; examples include using wind and solar energy, new climate-friendly cars, and energy-efficient lighting.

Pollution is the term used to describe the entry of pollutants into the environment. Noise, water, and air pollution are only a few of the several types of pollution. There is a direct relationship between the rise of pollution levels and illnesses among people. Therefore, it is important for everyone to be knowledgeable about pollution, its impacts, and effective ways to eliminate it. Our environment needs a balanced combination of all components, just like our body requires a balanced diet. The environment is polluted by any substance that is present above that limit for example rise in the levels of nitrogen oxides and carbon dioxide in the atmosphere causes harm to human health due to poor air quality.
All forms of pollution, whether in the air, water, soil, or noise, have a negative impact on living things. Deadly diseases that are brought on by the contamination of soil, water, air, or sound affect organisms.
Among the most common disorders brought on by air pollution are acute lower respiratory infections in children, ischemic heart disease, stroke, lung cancer, chronic obstructive pulmonary disease (COPD), and lung cancer. Air pollution is a major contributor to a number of ailments in India, including strokes, bronchitis, heart attacks, lung diseases, cancer, and early mortality from heart disorders. The most pressing issue in the world now is global warming, which is caused by air pollution.
Around the world, poor drinking water quality is the reason behind 50% of child deaths and 80% of illnesses, including more than 50 different diseases. Water pollution causes diarrhoea, skin diseases, malnutrition, and even cancer, as well as other issues that are related to it.
Every day, noise pollution has an effect on millions of people. The most frequent result of this is noise-induced hearing loss (NIHL). Loud noises have the potential to cause stress, high blood pressure, heart disease, and sleep difficulties. Children in particular are prone to these health issues across the board in terms of age groups. Noise pollution is extremely harmful, and it’s especially deadlier for people with heart issues.
Use of the 3Rs, or reduce, reuse, and recycle, is the first step in reducing pollution. People should use air conditioners less since they generate noxious gases, such as ozone-depleting chlorofluorocarbons, which will minimise air pollution.
Reducing the number of vehicles on the road will also help to clean up the planet’s air. The more often cars are used, the more dangerous chemicals like sulphur dioxide, nitrogen oxides, carbon monoxide, and hydrocarbons that contribute to major air pollution are released into the atmosphere.
Increasing public awareness is a further means of reducing pollution on Earth. Through programmes like the “Go Green” campaign, which urges people to plant more trees and use recyclable materials in their daily lives, awareness can be raised about the significance of eliminating pollution on Earth. The “Earth Hour” is another globally recognised event that calls for everyone to turn off all lights for one hour in order to raise awareness of the significance of reducing electricity usage in order to minimise pollution on Earth.
The government’s obligation to maintain national laws is one way to reduce pollution on Earth. Offenders should be subject to harsh penalties, such as increased fines and longer prison terms, which will force them to reconsider their influence on the environment and serve as a message to those who are not currently involved but who might be in the future.

Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants.
Biology, Ecology, Health, Earth Science, Geography
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 âchemical poisons used to kill weeds and insectsâ seep into waterways and harm wildlife . All living thingsâfrom one-celled microbes to blue whalesâdepend on Earth âs 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 peopleâs 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 âequatorial smoke stream .â In fact, this smoke stream was a jet stream , a wind high in Earthâs atmosphere that Krakatoaâs 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 âcoal, 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 canât survive . In Sweden, acid rain created thousands of â dead lakes ,â 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 Earthâs upper atmosphere. The ozone layer protects Earth by absorbing much of the sunâs 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 â ozone hole .â 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 canât 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 worldâs 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 â dead zones â in the worldâs 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 areaâs 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 riverâs 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 didnât 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'iâs largest industry . Polluted beaches discourage tourists from investing in the areaâs 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 worldâs second-largest producer of greenhouse gases, did not sign the agreement. Other countries, such as China, the worldâs 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.

Environmental pollution is the unwarranted discharge of mass or energy into the planet’s natural resource pools, such as land, air, or water, which detriments the environment’s ecological stability and the health of the living things that inhabit it. There is an intensified health risk and pollution in middle and low-income countries due to the increased use of pesticides, industrialization, the introduction of nitrogen-based fertilizers, forest fires, urbanization, and inadequate waste management (Appannagari, 2017). Air pollution, lead and chemicals exposure, hazardous waste exposure, and inappropriate e-waste disposal all result in unfavorable living conditions, fatal illnesses, and ecosystem destruction. The essay will provide an overview of pollution and proffer solutions to combating pollution for a sustainable environment and health.
In addition to hindering economic development and considerably accelerating climate change, pollution exacerbates poverty and inequality in urban and rural areas. The most pain is always experienced by the poor, who cannot afford to protect themselves against pollution’s harmful effects. The main environmental factor contributing to sickness and early mortality is pollution due to premature deaths resulting from pollution (Appannagari, 2017). Due to the unacceptably high cost to human capital and health, as well as the resulting GDP losses, pollution must be addressed. Through initiatives like reducing black carbon and methane emissions, which are responsible for air pollution and climate change, pollution management can also significantly contribute to climate change mitigation (Appannagari, 2017). Additionally, pollution control can promote competitiveness through, for instance, job growth, increased energy efficiency, better transportation, and sustainable urban and rural development. Below are the various approaches for solutions to health and pollution problems.
First, governments should evaluate pollution as a national and international priority and integrate it into the city and country planning process. Pollution affects the health and well-being of societies and, as such, cannot be solely viewed as an environmental issue (The Lancet Commission on Pollution and Health, 2017). All levels of government should give pollution prevention a high priority, incorporate it into development planning, and tie it to commitments regarding climate change, SDGs, and the prevention of non-communicable diseases. Some options are both affordable and offer good returns on investment.
Secondly, governments should increase funding for pollution control and prioritize it by health impacts. There should be a significant increase in the financing for pollution management in low- and middle-income nations, both from national budgets and international development organizations (The Lancet Commission on Pollution and Health, 2017). The most effective international support for pollution reduction is when it mobilizes additional actions and funding from others. Examples include helping towns and nations that are quickly industrializing concerning technical capacity building, regulatory and enforcement support, and support for direct actions to save lives. Monitoring financing initiatives are necessary to determine their cost-effectiveness and to raise accountability.
Thirdly, organizations should work to build multicultural partnerships for pollution control. Public-private partnerships and interagency cooperation can be powerful tools in creating clean technology and energy sources that will ultimately prevent pollution at its source (The Lancet Commission on Pollution and Health, 2017). Collaborations between ministries that include the ministries of finance, energy, development, agriculture, and transport, as well as the ministries of health and the environment, are crucial in pollution control. Governments should promote monitoring systems that could identify and apportion pollution sources, measure pollution levels, guide enforcement, and assess progress toward goals. The use of new technology in pollution monitoring, such as data mining and satellite images, can boost effectiveness, broaden the monitoring area, and cut costs.
One of the main issues facing the world in the current period is pollution. Natural resources are depleting daily due to car emissions, new technologies, factories, and chemicals added to food. All of these factors seriously harm the world. However, the problems caused by pollution can be prevented by building multicultural partnerships, increasing funding for pollution control, integrating it into the country’s planning process, and adopting new technology for monitoring pollution. Preventing pollution lowers the cost to the environment and the economy.

Pollution essay in english, what is pollution pollution types, causes and effects of pollution..
I have written an essay on Pollution in English for class 10. In the Pollution Essay we get to know on these issues – What is Pollution? Pollution types – air, water, noise, environment, Global Warming, and Climate Change.
Present scenario of pollution.
Prominent steps taken to curb the pollution, role of uno in curbing pollution.
Pollution is the presence or introduction into the environment of a substance or thing that has harmful or poisonous effects. Pollution can take many forms, and it can occur naturally or as a result of human activities . Some common types of pollution include air pollution, water pollution, and soil pollution . Pollution can have a variety of negative impacts on the environment, including harm to wildlife and natural ecosystems, as well as negative effects on human health. It is important to reduce pollution and protect the environment to ensure the long-term health and sustainability of our planet.
Pollution is a key issue that has been affecting our earth. Although it is an issue that has been prevalent since ancient times, in the 21st century its harmful effect has been felt on a large scale.
Although the governments of different countries have taken several major steps to curb these effects, there is still a long way to go.
Several natural processes and cycles get disturbed due to this. Not only that, many flora and fauna today either have gone extinct or are endangered. Due to the rapid increase in the amount of pollution, animals are losing their habitat at a rapid speed.
Pollution has affected several major cities across the globe. A majority of these polluted cities lie in India. Some of the most polluted cities in the world are Delhi, Kanpur, Bamenda, Moscow, Heze, Chernobyl, Beijing among others.
Although these cities have taken several steps to curb pollution , they still have a long way to go. The air quality of these places is poor and there are cases of land and water pollution as well. Now it’s time that the administration of these cities prepares strategies to check these issues.
Basically, there are four categories of pollution –
Letâs discuss the all the Pollution types  one by one:
a) Emissions from vehicles, such as cars, trucks, and buses b) Industrial activities, such as the burning of fossil fuels and the release of chemical byproducts c) Agricultural practices, such as the use of pesticides and fertilizers d) Household products, such as cleaning supplies and personal care items e) Construction and demolition activities f) Waste disposal and landfills g) Power plants
a. Agricultural runoff : Pesticides, fertilizers, and animal waste can run off of farmland and into nearby bodies of water, polluting the water. b. Industrial waste : Many industries release chemicals and other waste products into bodies of water, which can pollute the water. c. Sewage and sewage treatment plants : If sewage treatment plants are not properly maintained, sewage and other waste products can be released into bodies of water, polluting the water. d. Oil spills : Oil spills can occur as a result of human activities, such as the transportation of oil, or they can occur naturally. Oil spills can have serious negative impacts on the quality of water. e. Leaks and spills : Accidental leaks and spills of chemicals and other substances can pollute bodies of water. f. Litter: Litter, such as plastic bags and bottles, can end up in bodies of water, where it can harm wildlife and pollute the water. g. Land development : Land development and construction activities can lead to soil erosion, which can in turn cause water pollution.
Soil pollution can have serious consequences , including harm to plants and wildlife, contamination of the food supply, and negative impacts on human health. It is important to reduce soil pollution and protect our soil to ensure the long-term health of our planet.
Often, the day after the festival of Diwali it is reported in the media how the bursting of crackers caused an increase in noise pollution in major cities of India.
Although these are the four major categories of pollution lifestyle changes have caused several other types as well such as Radioactive Pollution , Light Pollution among others.
If a place ends up getting light in excess or in an unwanted amount, then it contributes to light pollution. Nowadays, several urban areas are facing unwanted glares in excess amounts.
This is due to the fact that most Indian cities such as Mumbai, Bangalore, Delhi, Chennai, etc. have an active nightlife.
We are living in the nuclear era. Since a lot of countries are developing their own nuclear devices, it has lead to an increase in the presence of radioactive substances in the atmosphere of the Earth.
This is known as radioactive pollution . Handling and mining of radioactive substances, testing, minor accidents occurring in radioactive power plants are other major causes contributing to radioactive pollution.
Global Warming is another name for climate change. The blanket of pollution that traps the heat around our planet is the main reason why global warming is increasing nowadays. As humans burn fossil fuels, vehicles emit harmful gases, jungles burn at alarming rates – all these factors are the main reasons.
Once it enters the earthâs atmosphere, eventually spreading across the globe. As a result, heat gets trapped around the earth for the next 50 or 100 years after it starts emitting again.
The worst part is harmful gases such as Carbon Dioxide have increased at an alarming rate. Due to this, the upcoming generation will feel the effects of global warming for hundreds of years.
The authorities at the national and international levels have taken several steps to curb the pollution issue. Some of these are as follows:
Under its banner, the UNO in 1972 had initiated United Nations Environment Program (UNEP) in order to address the issue of pollution. It has issued several issues such as climate change, ecosystem management, environmental governance, resource efficiency, etc. It has lead to several successful treaties such as the Montreal Protocol (1987) to limit the emission of gases that were thinning the protective ozone layer, Minamata Convention (2012) to limit the use of toxic mercury, etc. UNEP sponsored âSolar Loan Programmeâ where lakhs of people from different countries were provided with solar power panels.
Although the authorities of different cities are working hard to curb the pollution issue, however, it is the duty of citizens and common people also to contribute to this process. Few of the important ways to curb all kinds of pollution are:
Pollution is a problem that we need to solve at the earliest so that humans can live safely on this planet. It is important that we follow the suggested measures to curb this issue. Its our responsibility to make our place a better place for living. In order to make the Earth survive, we have to stop polluting it.

Introduction.
Pollution has become a very common yet serious issue in todayâs world. It has been there in different forms since a long time even before human evolution such as volcanic eruptions, wildfire which lead to various photochemical reactions in the atmosphere. The current concern is that it is rising day by day due to various resources of pollutants. And, one of the main pollutants are humans and man-made machines. It is right to say that pollution is damaging the mother earth severely and we, humans, should play our part to prevent it from happening.
Pollution sepsis is the presence of contaminants in the natural environment that causes harm and damage and therefore leads to adverse changes.
There are mainly three kinds of pollution - 1) Air Pollution, 2) Water Pollution, and 3) Soil Pollution.
Air Pollution
Air Pollution occurs due to the presence of harmful gases and substances in the air. It is due to vehicle emission, dust and dirt, poisonous gasses from the factories etc. To reduce air pollution, we should use carpooling or public transport rather than using our private mode of transportation whose harmful gas emission only adds to the problem, we should also actively avoid burning trash or other materials etc.
Water Pollution
Water Pollution happens when toxic substances get mixed in various water bodies such as lakes, oceans, rivers etc. Here toxic substances refer to the Chemical fertilizer, Industrial waste, Sewage and wastewater, Mining activities, Marine dumping etc.
Soil Pollution
Soil pollution depicts the contamination of soil due to the presence of toxic substances due to Excessive use of fertilisers and pesticides, deforestation, industrial waste etc . To maintain the soilâs fertility, the government must limit the usage of fertilizers and plant more trees.
There are a few other pollutants causing pollution apart from the aforementioned ones, such as Radioactive pollution. This is one of the rarer types of pollution. It occurs due to the presence of radioactive substances such as the presence of nuclear waste in air, solids, liquids or any other place.
Pollution is increasingly having a major effect on the health of human lives. People are gettin g affected by different types of deadly diseases due to the various pollution in air, water and soil. Here are the different diseases humans face due to different pollution.
Air is an essential part of human life. Humans cannot live without breathing air. But, air pollution causes major damage to human lives. Here are some of the major diseases caused due to air pollution.
Lung cancer
Major coronary heart disease
Respiratory problems
Water is another source of life. Any living being cannot survive without drinking water. But the continuous degradation and pollution of major water bodies are also causing deadly diseases to humans and animals. It is also affecting marine life. Since water is consumed all the time, itâs pollution is causing a lot of deadly diseases. Some of the major diseases caused by water pollution are as follows:
Hepatitis A
Diarrhoea
Soil is an important part of our lives. The land on which we are walking or travelling is made with soil. Due to all the chemicals mixed with the soil and degradation due to the same, it is inevitable that many harmful chemicals come in contact with our body and cause many skin diseases or in forms of food crops that are planted on such polluted soil. Direct contact can cause a lot of problems for us humans. Some of the major diseases caused due to soil pollution are as follows:
Different types of cancer
Damage of the nervous system due to contact with lead present in the soil.
liver and kidney failure
The degrading quality of all the important elements like air, water and soil is affecting the lives of many children, adults as well as animals. We need to keep our environment safe and use effective methods to reduce pollution.
Some of the effective methods to reduce air pollution are as follows:
Regulation of air through chimneys: The industries should disintegrate the harmful gas from the air prior to its release from the chimneys. They should check and avoid using harmful gases, which are the major causes of air pollution.
Use of public transport or cycle: If you are travelling to distant places, it is recommended to take public transport. Or if you are going to any shops or buying any garment, it is always better to use your cycle. Public transport can take you to different places along with other people; this will help reduce air pollution. If you can cycle, it will reduce air pollution and another added benefit is that it will keep your health in check.
Reduction of fires and smokes: In the dry season, many people burn plastic, papers, dry leaves, which creates a big fire and smoke that creates a harmful layer of fog suspended in the atmosphere. It is better if you stop burning plastic to reduce smoke.
Some of the effective methods to reduce water pollution are as follows:
Avoid disposing of plastic and waste materials: To keep the water free from any pollution, the first thing is to avoid disposing of any sort of plastics or food waste water material in water. The waste materials get dissolved in the water and harm the aquatic life along with those who drink the water.
Reduce use of chemicals: you should avoid purchasing harmful chemical products that can get mixed with the water and pollute it. The biggest examples are pesticides and insecticides, which causes a major effect on marine life.
Reduce use of detergents: Detergents have many strong chemicals which can cause the leather to water and wash your clothes. If these detergents get mixed with water, they can pollute the soil.
Some of the methods to reduce soil pollution are as follows:
Avoid disposing of harmful chemicals: The industries should avoid disposing of harmful chemicals in the soil. It can change the structure and components of the soil making it an unusable surface of land for vegetation.
Eat food in biodegradable containers: As you dispose of the food containers in dustbins, it is good to use biodegradable food containers despite using plastic containers, which are harmful to the soil.
Plant more trees: The structure of the soil can be improved by planting more trees. Trees help to hold the soil together and improve the soil quality. Hence we should plant more trees.
Upon learning about the harmful effects of pollution, it is everyoneâs responsibility to take some steps towards prevention. We should be aware of all the possible preventive measures to help reduce every kind of pollution such as to curb air pollution, we should avoid bursting crackers during any festival or using public transport or carpool to reduce air pollution or cutting down the usage of loud loudspeaker, and public honking would help in noise pollution. We should always be aware of this situation and take measures accordingly. Itâs us who should be cautious in the beginning and make everyone else surrounding us conscious as well. We should take eco-friendly steps like planting more trees, reducing the usage of plastic, using more sustainable products in the household etc. while talking about the pollution of the entire world, you should always remember that every small step will lead to a bigger impact one day.
In a nutshell, every kind of pollution leaves a huge negative impact on our environment, human lives, animals etc. We, as responsible citizens, must take steps towards a better tomorrow. We must join hands to take various initiatives and fight against this problem. A lot of innocent lives are put in danger due to pollution every day. If we donât do anything from now on or take a stand to make the earth pollution-free, then the doomsday will be upon us very soon.

Environmental pollution refers to the introduction of harmful substances or products into the environment. It is a major problem in today’s world and has a profound impact on both the natural world and human lives.
The sources of environmental pollution are numerous and varied, including industrial activities, transportation, and household waste. One of the most significant contributors to environmental pollution is the burning of fossil fuels, which releases toxic chemicals and greenhouse gases into the atmosphere. This not only contributes to air pollution, but it also has a significant impact on climate change, causing rising temperatures, extreme weather events, and melting of polar ice caps.
Another major source of environmental pollution is the disposal of hazardous waste. This includes chemicals, batteries, and electronic waste, which contain toxic substances that can contaminate soil and groundwater, leading to serious health problems for both humans and wildlife.
The effects of environmental pollution are far-reaching and often devastating. It can cause serious health problems for humans, including respiratory problems, heart disease, and cancer. Additionally, environmental pollution can have a significant impact on wildlife, causing a decline in biodiversity and threatening species with extinction.
To address environmental pollution, it is essential that we take a multi-faceted approach, addressing both the causes and consequences of pollution. This may involve reducing the use of fossil fuels and implementing clean energy technologies, as well as improving waste management and increasing public awareness about the impact of pollution.
In conclusion, environmental pollution is a serious problem that has a profound impact on both the natural world and human lives. To address this problem, it is essential that we take a comprehensive approach, addressing the causes and consequences of pollution and working to reduce its impact on the environment. By taking action now, we can protect the future of our planet and ensure a healthy and sustainable future for generations to come.
Environmental pollution is one of the biggest threats to our planet today. It affects both the environment and human health, and it’s becoming more and more pervasive in our daily lives. In this essay, we’ll explore what environmental pollution is, how it affects us, and what the most effective solutions are to reduce its impact on people and the planet.
There are many different types of environmental pollution. Some of the most common include air pollution, water pollution, and soil contamination. Each type of pollution has different causes and effects. Air pollution is typically caused by emissions from factories and automobiles. These emissions can contain harmful chemicals that can cause respiratory problems, heart disease, and cancer. Water pollution is often caused by sewage or agricultural runoff. This pollution can contaminate drinking water supplies and make people sick. Soil contamination can be caused by hazardous waste disposal or mining operations. This contamination can make crops unsafe to eat and cause health problems in people who come into contact with it.
There are many causes of environmental pollution. The most common cause is the release of harmful chemicals into the environment. These chemicals can come from factories, power plants, cars, and other sources. They can pollute the air, water, and soil. They can also cause health problems for people and animals.
Other causes of environmental pollution include sewage, agricultural runoff, and mining. Sewage can contain harmful bacteria and viruses that can pollute water supplies. Agricultural runoff can contain pesticides and fertilizers that can pollute rivers and lakes. Mining can release harmful metals and minerals into the environment.
There are many different types of pollutants that can have an adverse impact on the environment. Some of the most common pollutants include:
âą Air pollution â This is one of the most visible forms of pollution and can cause a range of health problems, including respiratory illnesses.
âą Water pollution â This can lead to contamination of drinking water supplies and also harm marine life.
âą Soil pollution â This can contaminate crops and lead to soil erosion.
âą Light pollution â This can disrupt the natural circadian rhythms of animals and cause light-sensitive species to suffer.
All of these pollutants can have a serious impact on the environment, both in terms of the immediate damage they cause and also the long-term effects. It is therefore important to be aware of the different types of pollutants and their potential impacts.

Pollution, the presence of unwanted substances known as pollutants in the environment, poses an immediate and severe threat to the delicate balance of our ecosystems. The recognition of the urgent need to address pollution is essential if we are to preserve the Earth and its biodiversity. This essay explores the various facets of pollution, its types, and the impact it has on major Indian cities such as Delhi, Noida, Ghaziabad, Lucknow, and Varanasi.
Pollution occurs when external compounds, primarily generated by human activities, enter the environment as unwanted entities known as pollutants. These pollutants cause significant harm to the environment, affecting water bodies, air, flora, and fauna. The consequences of pollution extend globally, contributing to phenomena like the greenhouse gas effect, global warming, and acid rain.
Imagine bustling cities in India, like Delhi or Varanasi, filled with life and energy. However, there’s a problem casting a shadow over this vibrancy â pollution. In this exploration, we’re going to look at how pollution affects the air, water, and soil in cities such as Delhi, Noida, Ghaziabad, Lucknow, and Varanasi. The goal is to understand the challenges these cities face and why it’s so important for everyone to work together to tackle pollution and ensure a healthier future.
Delhi, the National Capital Territory, faces a dire situation in terms of air quality index (AQI). According to the World Health Organization, Delhi ranks lowest among 1650 major cities worldwide. The air quality, especially during the winter months from October to December, rapidly deteriorates, reaching hazardous levels.
The AQI for Delhi remains moderate (101-200) from January to September but spikes during winter, often surpassing 500. Particulate Matter (PM2.5 and PM10) levels soar well beyond safe limits, primarily due to factors such as vehicular emissions, industrial activities, and the traditional practice of burning paddy crop roots in neighboring states.
Noida, bordering Delhi in western Uttar Pradesh, faces similar challenges with poor air quality. Intensive construction activities, heavy vehicular pollution, and cold winter air contribute to the formation of a thick smog, impacting the Air Quality Index. The PM levels in Noida compete with Delhi, often reaching hazardous levels during the winter months.
Ghaziabad frequently tops the list of North Indian cities with the worst AQI and pollution levels. Industrial pollution and waste burning are major contributors to Ghaziabad’s poor air quality. Located on the outskirts of the city, industries emit dense smoke, exacerbating pollution. The PM10 levels in Ghaziabad often surpass permissible limits, reaching alarming levels, especially during festivals like Diwali.
Lucknow, the capital of Uttar Pradesh, experiences fluctuating AQI levels, ranging from moderate to poor. While not as severe as Delhi NCR, the air quality in Lucknow is still alarming, demanding concrete action. The quantity of suspended Particulate Matter has increased significantly in residential areas, posing health risks. The city’s air contains fine PM2.5 particles, reaching hazardous concentrations.
Varanasi, the ancient pilgrimage city and the parliamentary constituency of Indian Prime Minister Narendra Modi, faces environmental challenges due to ongoing construction activities. Varanasi’s AQI is ranked third on the World Health Organization’s list of the fifteen most polluted cities globally. The ongoing construction work contributes to a decline in air quality, with AQI reaching up to 300, falling in the “Poor” category. Particulate Matter, especially PM2.5, poses health risks to the city’s residents.
The impacts of pollution are profound, impacting ecosystems, biodiversity, and the well-being of humans. Prolonged exposure to air pollutants is associated with cardiovascular diseases, while contaminated water sources contribute to the spread of waterborne diseases. Soil pollution poses risks to food safety, and noise pollution leads to stress and hearing loss. Additionally, light pollution disrupts wildlife behavior.
Importantly, pollution transcends local boundaries; its consequences are felt globally. Greenhouse gas emissions contribute significantly to global warming, causing adverse effects on climate patterns. The accumulation of plastic waste in oceans not only harms marine life but also infiltrates the food chain, posing threats to human health. Furthermore, pollution-induced stress and habitat destruction contribute to the loss of biodiversity, impacting ecosystems on a global scale.
Stringent environmental regulations need to be implemented and enforced by governments to combat pollution effectively. Offering incentives to industries for adopting cleaner technologies, investing in renewable energy sources, and practicing sustainable waste management is vital. International cooperation is essential to tackle global environmental challenges, with countries collaborating to decrease greenhouse gas emissions, combat plastic pollution, and safeguard biodiversity.
Pollution remains a pressing issue affecting major Indian cities, with severe implications for the environment and public health. The need for immediate and concerted efforts to address pollution is evident, as evidenced by the deteriorating air quality in cities like Delhi, Noida, Ghaziabad, Lucknow, and Varanasi. It is imperative that governments, industries, and individuals collaborate to adopt sustainable practices, enforce regulations, and invest in technologies that mitigate the environmental impact. Only through collective action can we hope to mitigate the menace of pollution and ensure a healthier and sustainable future for our planet.
Pollution is a critical environmental issue that demands urgent attention and concerted efforts at local, national, and global levels. The consequences of pollution are profound, affecting ecosystems, biodiversity, and human health. It is imperative that individuals, communities, industries, and governments work together to adopt sustainable practices, enforce regulations, and invest in technologies that minimize the environmental impact.

Furthermore, air pollution essay helps students to realize the gravity of the scenario and enable them to take action. Some as simple as using public transport or even carpooling will help reduce a significant amount of air pollution. Read on to discover how to write an engaging essay on air pollution.
Please consider adopting the following points when writing an essay on air pollution. These tips are also helpful for other essay topics as well:
Air pollution is a serious issue and a cause for major concern in todayâs world. A report published in 2014Â by the World Health Organisation states that 4.21 million individuals died prematurely in 2012 as a result of air pollution. Air pollution existed much before humans, in the form of volcanic eruptions and forest fires. However, it became much more prevalent after the Industrial Revolution.
Rapid industrial growth, unregulated emissions and a host of other issues significantly contributed to the rise in air pollution. In some cases, the severity of air pollution reached an extent where government intervention was necessary. The Great Smog of London, 1952, was an extreme case of air pollution where visibility was severely hampered. It also caused a host of illnesses and the consequent deaths of countless civilians. In November 2017, the levels of air pollution in Delhi were ten times above the safe limits. For reference, the healthy air quality index is between 0 to 50, but during that particular time period, the air quality index hit 500+. This event is now called the Great Smog of Delhi.
An air quality index of 500 and above indicates that the air is heavily polluted and will cause irreversible lung damage and a host of other illnesses to everyone who is exposed to it. Therefore, to avoid such situations in the future, relevant actions must be implemented.
Air pollution may seem like the result of anthropological activities, however, it has been around even before humans evolved. Places which are naturally arid and have minimal vegetation are prone to dust storms. When this particulate matter is added to the air, it can cause health issues in animals exposed to the dust storms.
Furthermore, active volcanoes pump extremely large amounts of toxic plumes and particulate matter into the atmosphere. Wildfires also pump large amounts of carbon monoxide into the atmosphere and hamper photosynthesis for plants. Even animals, especially ruminants such as cows contribute to global warming by producing large quantities of methane, a greenhouse gas.
However, air pollution was never a major concern until the industrial revolution. Industries grew rapidly, untreated emissions were pumped into the atmosphere, and the rise of automobiles significantly contributed to air pollution. Such activities continued without any restrictions until they started to cause a wide range of repercussions.
In humans, air polluted with contaminants can cause a wide array of illnesses ranging from asthma and bronchitis the various forms of cancer. Air pollution is not only present outdoors; interior air pollution is also a great concern. Recent research has actually found credible evidence that room fresheners have the many compounds within them, some of which are classified carcinogens. This means some of those compounds present in the aerosol has the potential to cause some forms of cancer. Other sources of air pollution can include gases such as carbon monoxide and radon.
Radon, in particular, is quite alarming. It is an odourless, colourless gas that occurs naturally. It is found in the soil as Uranium, which breaks down and eventually turns into radon gas. Radon has limited repercussions on health if exposed to low concentrations, however, when this gas gets trapped indoor, the higher levels of concentration can have wreak havoc or ultimately be lethal. Radon is also reported to be released from building materials such as granite. Exposure to radon causes no immediate health effects, but long term exposure has the potential to cause lung cancer.
Air pollution not only affects the lungs but the central nervous system too. It has been linked to a lot of diseases such as schizophrenia and autism. A study also implied that it can cause short-term memory losses or distortion of memory.
Historically, air pollution has caused many crises with the worst ever being the Bhopal Disaster in 1984. Fatalities were estimated at 3,800, with at least 600,000 injured. Next in severity was the Great Smog of 1952 which formed over London, killing an estimated 4,000 civilians over the course of four days.
Though measures have been taken to reduce the effects of air pollution, a lot of irreversible damage has been done. For instance, the effects of global warming have drastically increased; this is very apparent with the rise in sea levels and melting glaciers. If the ice caps continue to melt, then we will have to face drastic repercussions. Scientists have proposed a hypothetical scenario where the greenhouse effect becomes âuncontrolled.â Here, greenhouse gases build up and temperatures continue to rise steeply. Oceans will start to evaporate, adding more water vapour into the earthâs atmosphere. This intensifies the effect, reaching a point where temperatures are sufficiently high for rocks start sublimating. Though this scenario is hypothetical, some speculate that this phenomenon already occurred on Venus. The supporters of this theory back this up by claiming Venus has an atmosphere composed primarily of carbon dioxide. The theory also explains why Venus has an extremely high surface temperature of 462 degrees Celcius; which is in fact, the hottest planet in the solar system.
Hence, we need to reduce our impact on the planet and make a conscious effort to reduce air pollution. Explore more essay topics or other fascinating concepts by registering at BYJUâS

Below we have provided an Essay on Pollution in English, written in easy and simple words for class 3, 4, 5, 6, 7, 8, 9 and 10 school students. This essay is helpful for the aspirants preparing for the competitive exam too!
Pollution Essay: Pollution is one of the most commonly discussed topics in recent times. It is not only a threat to nature but also to all its creations. Pollution refers to the introduction of hazardous substances to our life-sustaining environment. It has adverse effects on the natural resources of our planet. These foreign particles which contaminate our environment are called pollutants. Pollution drastically affects our ecosystem. The balance in our ecological cycle gets disrupted. Moreover, flora and fauna suffer its consequences.
Animals lose their habitats and humans are prone to life-threatening illnesses. Today we have natural calamities like tsunamis, hurricanes, and floods. The air quality is critical, and on top, we are dealing with global warming. Humans play an active role in this event. Man made activities are major contributors to the ongoing pollution. Thus we need to tackle this problem without any further delay. To do so, we must have in-depth knowledge of this area. Let us get to know what the different types of pollution are and how they are caused.
There are four basic kinds of pollution. Let us go through them one by one.
Air Pollution
This is the type of pollution where the air gets contaminated by air pollutants. These toxic substances mainly include vehicular exhausts, smoke, industrial gases, chlorofluorocarbons, plastics, radioactive elements, etc. Volcanic eruptions also add to air pollutionâgases like carbon dioxide, sulfur oxides, ammonia decrease the oxygen content in the earthâs atmosphere. We need oxygen to breathe, and lack of it can have dangerous effects. Air pollution leads to various respiratory diseases and other severe ailments. Burning of fossil fuels and wildfires in the forests also contribute to air pollution. Numerous wildlife species suffer in this process. They lose their home, and some of them lead towards extinction.
Water Pollution
The addition of toxic products to water degrades its quality and makes it unfit for consumption. This is known as water pollution. Water is one of the most valuable resources of our planet. Our survival depends on it. However, chemical discharges from industries, sewage waste, domestic waste, and oil spills deteriorate the water quality and make it toxic. This hugely affects the biotic and non-biotic ecosystems. Consumption of this polluted water causes cholera, dysentery, typhoid, and many other diseases. Marine animals also become endangered due to its effect.
Soil Pollution
Contamination of soil is referred to as land pollution. Agricultural practices use pesticides, fungicides, and fertilizers which contaminates the land. Moreover, the dumping of industrial waste and e-waste also makes it hazardous. Biomedical waste and the handling of radioactive elements are also potential threats. Deforestation, construction and mining activities also harm the soil. When the agricultural lands get contaminated, harvested crops absorb the toxins which are then consumed by humans. This can cause a lot of health hazards.
Noise Pollution
Loud noises above a certain decibel are harmful to our environment and cause noise pollution. Honking of vehicles, loudspeakers, bursting of crackers, household chores, poor urban planning, and construction machines all are considered bad for our health. They cause stress and anxiety not only in people but also in animals. It can cause communication troubles, sleep disorders like insomnia, hearing loss, etc.
Pollution can affect your entire life in a way you can never imagine. They thrive in our atmosphere, but we cannot see them. Air pollution has been responsible for the depletion of the ozone layer. Another disastrous effect of it is global warming . It causes ailments like heart and lung diseases apart from asthma, allergies, and respiratory problems, etc. Water pollution is more hazardous. Humans are prone to diseases like jaundice, diarrhoea, and giardia. Various aquatic species lose their habitats in oil spills and cease to exist. Soil Pollution is capable of turning a piece of land completely unsuitable for farming.
It also leads to the reduction of the underground water table. Last but not least; noise pollution affects the health of an individual on a psychological level. Excessive sound can turn you deaf and can also make you suffer from chronic heart diseases. Apart from that, it always irritates and can also result in fluctuating blood pressure. These risks can be minimized if proper planning is done, and actions are taken. Therefore, we should take measures to reduce all kinds of pollution.
Though it is beneficial to learn what causes pollution and what its effects are, we must take steps to prevent it. Authorities have started implementing steps to curb this problem. Heavy penalties are being imposed on industries that violate the statutory limit of effluent discharge. The government has been encouraging people to switch to alternative forms of energy. We can start using solar panels, hydro-power turbines, wind energy, etc. Rainwater harvesting is also a renewable source for storing rainwater. It is our responsibility to help each other in this implementation process to minimize the consequences.
Air pollution can be significantly reduced by reducing the number of automobiles. We can utilize public transportation mediums for commuting. Also, biofuels like CNG help a lot in curbing emissions. The use of crackers during festivals must be cut down. We should adopt healthy habits like recycling of inorganic materials and compost of plant-based products. Planting more and more trees will ensure we have enough oxygen in our environment. Instead of pesticides, natural manures can be used for the same purpose. Water pollution can be prevented if we increase awareness amongst the masses. Campaigns can be organized for these purposes.

Macro-scale distribution of air pollution concentrations is influenced by factors including geography, weather, industry, transport and regulation. Pollution sources are unevenly distributed, with some communities disproportionately impacted by higher emissions. This study separates the effects of deprivation from ethnicity as factors that influence proximity to pollution sources. We combine recent decadal census data (2021) on socioeconomic deprivation and detailed population ethnicity at fine scales (Lower Super Output layer Area, LSOA n = 1600 people) with a 1 Ă 1 km sector-resolved atmospheric emissions inventory for NOx and primary PM2.5 in England. All 24 minoritised ethnic groups studied experienced higher average local NOx and PM2.5 emissions than socio-economically matched populations in the majority âWhite: English, Welsh, Scottish, Northern Irish or Britishâ ethnic group. Chinese, Arab and Bangladeshi communities experienced the largest disparity in NOx, with weighted emissions 100%, 91%, 89% higher than white populations of matched deprivation status. Bangladeshi, Pakistani and Roma groups experienced on average 40%, 40%, 36% higher PM2.5 emissions locally than matched white groups. For NOx the largest contributors leading to disparity, were road transport (48%), domestic combustion (23%) and industry (15%). For PM2.5 the greatest contributors to disparity were domestic combustion (53%), road transport (19%), and industry (11%). Living near to road transport and in city centres are frequently cited as primary drivers of ethnicity and deprivation-based disparities, however the analysis identifies that industrial, domestic and off-road sources create issues of the same magnitude, and disparities remain in suburban settings, smaller towns and some rural areas.
