paragraph on air pollution:
Air pollution refers to the phenomenon of harmful compounds in the form of gases and fine particles being released into the air thus polluting it. If the air is polluted we cannot breathe fresh and clean air. This affects the lives of humans and all other life forms adversely. Humans suffer from various respiratory and cardiac conditions due to air pollution. Air pollution also causes diseases affecting other organs of the body. It also causes cancer. Millions of people around the world die to air pollution-related diseases each year.
Air pollution is caused by a number of factors. Vehicular traffic is one of the causes of air pollution. When vehicles ply on the roads, the combustion of the automobile fuel, whether it is diesel or petrol, leads to the creation of poisonous gases that are released through the exhausts of the vehicles. These gases, in the form of smoke and fumes, pollute the air severely. Various alternative fuels such as compressed natural gas as automobile fuel are being used now-a-days. Battery operated vehicles are also being run.
Factories also contribute to air pollution in a big way. When various production processes are carried out in factories, they release smoke and fumes. These are then released into the air. We see black smoke emanating from chimneys or exhaust towers of factories.
Smoke is also caused due to the burning of fossil fuels like coal. The burning of farm wastes and other garbage, as also construction activity also lead to air pollution.
