Hi guys i am going to tells about environmental pollution. Environmetal is one of the greatest problems that the world is facing today is that of environmental pollution, increasing with every passing year and causing grave and irreparable damage to the earth. Environmental pollution consists of five basic types of pollution, namely, air, water, soil, noise and light.
Air pollution is by far the most harmful form of pollution in our environment. Air pollution is cause by the injurious smoke emitted by cars, buses, trucks, trains, and factories, namely sulphur dioxide, carbon monoxide and nitrogen oxides. Even smoke from burning leaves and cigarettes are harmful to the environment causing a lot of damage to man and the atmosphere. 
Chlorofluorocarbons (CFC),  released from refrigerators, air-conditioners, deodorants and insect repellents cause severe damage to the Earth’s environment.  This gas has slowly damaged the atmosphere and depleted the ozone layer leading to global warming.
