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.
