Pollution is when something is added to theenvironment harmful or poisonous to all living things. Smoke or dust in the air is a type of pollution . Sewage in drinking water is another type of pollution, containing germs andviruses. There are 3 kinds of pollution: water pollution, land pollution, and air pollution.

Air can be polluted by many things. Air pollution includes poisonous gases, sulphur dioxide, nitrogen dioxide, carbon monoxideand very small particulates. Smoke and harmful gases released by fires, industries and thermal power plants cause air pollution. Using coal and wood as fuels for fire cause a lot of air pollution. Petroleum produces less pollution per tonne, but it causes a lot of pollution since a lot of it is burned globally. Air pollution may cause breathing problems such as asthma or other health problems. It also causes diseases like cancer.

Water pollution is the presence of harmful materials in water, such as sewage, dissolvedmetals, waste from farms, factories and crude oil spilled from oil tankers. The three main substances that pollute water are nitratesfrom fertilizers, sewage and detergents.

Noise pollution (also known as sound pollution) is harmful to the brain and hearing of all animals and humans. This includes the sound of vehicles, loud speakers, airplanes, jets, train horns etc. Noise pollution can cause ear problems or even permanent deafness, especially to older people. It also causes brain related problems.

Soil pollution (also known as land pollution) is caused when man-made chemicals, such as hydrocarbons, heavy metals, and solvents, get into the soil.These chemicals come from industrial activities and from improper wastein disposal in leaky landfills. Soil pollution can cause health risks. The chemicals can produce harmful vapours, or they can contaminate water supplies underneath the polluted soil.

Plastic pollution is the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, or humans. It is caused because plastic takes thousands of years to decompose or mix in the earth.
