Nowadays, big cities are facing with air pollution, one of the most serious global issues. One of the causes is vehicular traffic. The combustion of the automobile fuel whether it is diesel or petrol, that powers a vehicle, leads to the release of poisonous gases released through the exhaust of the vehicle. Smoke generated by factories is also let out into the air leading to pollution. Moreover, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke polluting the air. Air pollution always has bad effects on our life. People around the world are suffering from respiratory and cardiac problems, and diseases such as cancer affecting other organs of the body too. To improve the air quality, people should plant more trees and use pubic transports instead of private vehicles.

The environment is very necessary to lead a healthy life. Our environment shapes a very important aspect of human life because that is where we find the requirements of life like air, water, and food. Due to global industrialization and modernization, there has been environmental pollution. Our lifestyle has also changed. The animals are on the verge of extinct day by day. The panda, the white tiger, Albatross are now not to be seen. They are few only and if environmental pollution continues then we are going to lose our animals in a few decades. The harmful and toxic gases which release 24×7 from the factories are mixing with air, thus causing air pollution. People dump all the waste materials in the river and sea, this way the water is also getting poisoned every day.
