Essay on Pollution

There are many causes of pollution. The most common cause of air pollution is the burning of fossil fuels such as coal, oil and gas. Burning of these fuels releases harmful substances like carbon dioxide, sulfur dioxide and nitrogen dioxide into the air. These substances can harm the environment and human health. Another cause of air pollution is the release of harmful substances into the air by factories and power plants. These substances can also harm the environment and human health.

The most common cause of water pollution is the release of harmful substances into water by factories and power plants. These substances can also harm the environment and human health. The most common cause of soil pollution is the release of harmful substances into the soil by factories and power plants. These substances can also harm the environment and human health.

Essay on Pollution (800 words)


Pollution refers to the presence of unwanted substances; Known as pollutants in the environment. Pollution is an immediate threat to the environment and causes serious damage. Recently, the world is recognizing the need to tackle pollution if the Earth and its biodiversity are to be preserved.

what is contamination

Pollution occurs when an unwanted foreign compound, primarily produced by human activities, enters the environment. These compounds are known as pollutants and cause serious harm to the environment. Everything that is part of the environment, i.e. water, air, flora and fauna, is affected by pollution in some way or the other. Apart from this, pollution also causes global effects like greenhouse gases, global warming and acid rain. Global warming refers to the increase in the average temperature of the earth’s surface and results in conditions such as famine, floods and droughts. Below we will analyze the effects of pollution in the main cities of India such as Delhi, Noida, Ghaziabad, Lucknow and Varanasi.

You should know that an AQI between 0 and 50 is considered “good”; 51 to 100 is considered “satisfactory”; 101 to 200 is considered “moderate”; 201 to 300 is considered “bad”; 301 to 400 is considered “very poor”; 401 to 500 is considered critical and values over 500 are considered “critical-plus or emergency”.

Today, human life on planet Earth, as well as the existence of other flora and fauna, is largely under threat due to pollution. Pollution affects everything necessary for survival: natural resources, species, health, etc.

what is contamination

When any unwanted foreign substance produced by human activity enters the environment it causes pollution. The causes of pollution are always human-induced and the natural causes of pollution are almost negligible.

There are many human activities that cause pollution. Tons of toxic waste generated as by-product in factories is dumped into rivers and streams, polluting them; Transport vehicles emit thousands of cubic meters of harmful gases that pollute the air; Improperly disposed waste from urban settlements spreads over land and water, causing land and water pollution.

Now that we know what pollution is, we will discuss some of its important effects.

Effect of pollution on the environment.

Pollution has wide-ranging effects on the environment, as discussed below:

1) Soil poisoning

Soil poisoning occurs as a result of pollution caused by agricultural activities such as the use of chemical fertilizers. Chemical fertilizers are made of harmful chemical compounds that leach into the soil and eventually make it toxic. This affects both plant and animal species that depend on soil purity for their survival.

2) polluted air

Pollution pollutes the natural air, making it harmful to breathe. For example, toxic gases emitted from transport vehicles get into the air and cause pollution. When this air enters the body of a human being or animal, it causes serious respiratory diseases. Some species of animals and plants that are highly sensitive to this type of pollution die.

3) polluted water body

Due to inadequate disposal of waste generated in human settlement areas, it reaches our natural water bodies in the form of runoff. Municipal waste contains many toxic compounds including plastics. This waste is not biodegradable and remains in water, making it dangerous to drink. This is also causing a decline in the populations of aquatic species that are very sensitive to pollution.

4) Global warming

Global warming is one of the main effects of pollution which produces many environmental effects. Gaseous pollutants such as carbon monoxide (CO) and carbon dioxide (CO2) released from the burning of fossil fuels persist in the atmosphere, causing the greenhouse effect. On the other hand, greenhouse effect is responsible for many factors like unpredictability, climate change which causes drought, famine etc., depletion of aquatic species like coral reef, fish etc.

5) extinction of species

The most significant impact of pollution on the environment is the loss of species. When polluting substances reach our natural resources, they harm living species in some way or the other. Gaseous pollutants cause serious respiratory diseases and also reduce the life expectancy of fauna and flora.


The impact of pollution on the environment is far-reaching. If concrete measures are not taken to stop pollution, not only will the impact of pollution persist but the future of many species will also be in danger. The rate at which pollution causes damage far exceeds its repair. Although it may take centuries to reverse the damage we have caused to the environment, it will not be an easy task and will require great discipline and willpower to tackle pollution.

Essay on Pollution (200 words)


In simple words, pollution occurs when something unwanted enters your natural environment. The release of poisonous gases when plastic is burned is pollution; Pollution is the release of harmful chemicals into the soil when mixed with chemical fertilizers; When the waste removed from your house somehow reaches the open environment, it causes pollution. Similarly, there can be many other examples of pollution also. For now, we will discuss the types of pollution below.

Types of Pollution

Below are the five main types of pollution:

1) soil pollution

Soil pollution can be caused by many factors such as improper waste disposal, use of harmful chemicals in agricultural industry, etc.

2) Noise pollution

Noise pollution refers to the presence of excessive noise generated by human activities such as road transport vehicles, jet aircraft, busy markets, loudspeaker announcements, etc.

3) water pollution

Its main sources are water from urban settlements, agricultural fields and by-products from factories.

4) Air pollution

Its main sources are the burning of fossil fuels in transport vehicles and smoke from factories.

5) Light pollution

Light pollution refers to the excessive presence of light in a polluted area, enough to interfere with the natural environment.


Whatever be the type of pollution, it always has harmful effects on the environment and human health or affects some living species on earth. Light pollution confuses birds when they sleep, often leading to fatal accidents.

Pollution today has become a global concern for both the environment and the health of the planet’s flora and fauna. Pollution has a wide-ranging impact on the environment including natural resources. This causes natural elements to get contaminated and become harmful for use, ultimately affecting life on the planet.

What is contamination?

When any polluting substance enters our natural environment and pollutes it, then this process is called pollution. These pollutants are mostly caused by human activities, which are mostly economic in nature. To give some examples: Carbon monoxide (CO) emitted by transport vehicles pollutes the air; Oil released by large sea vessels pollutes the ocean and makes the water harmful to aquatic life.


Pollution is the immediate and most pressing threat facing the environment today. Time is continuously passing by and the damage to the environment is increasing with every passing moment. There is a need for immediate action by the government and other stakeholders to protect the environment from pollution.

Pollution refers to the presence of pollutants in the natural environment. Some examples of polluting substances are: gases such as carbon dioxide (CO2), carbon monoxide (CO), etc.; Solid pollutants such as plastics, waste water, etc., and chemicals such as fertilizers, as well as substances produced as by-products in factories, transportation, etc.

The immediate effect of pollution is that it makes the earth’s natural resources unusable or in other words harmful for use and also causes species depletion and ecological imbalance.

It is very important to take necessary preventive and proactive measures to save the earth and its inhabitants from further harm caused by pollution.
