It reduces ozone layer atmosphere and contributes to global warming.


Air pollution is caused when the air in the atmosphere is filled with particular matter. The largest source of pollution in cities is from vehicle exhaust fumes. Carbon monoxide is the largest air pollutant exhausts by the vehicles. It is poisonous, odorless, colorless gas that is formed when burning fossil fuels such as petroleum and coal. Chemicals and toxic pollutants like nitrogen oxide, carbon dioxide reacts with water molecules in the atmosphere to produce acid rain. Such types of pollutants comes out from factories and automobiles.

Another source of air pollution is dirt that goes airborne due to everyday labor in the agricultural and construction industry. One more reason is volcano, dust storms and forest fires are causes of natural air pollution.

Polluted air reduces the body capacity to fight other injections in the respiratory system. Frequent exposure to polluted air increases the risk of cardio vascular disease. Breathing air that filled with fine particulate matter can induce hardening of the arteries. Acid rain contains hydrogen ions which can damage trees, crops, harm marine animals and induce corrosion in metals. People suffered with heat disease children and older people are more sensitive to air pollution.

Air pollution affects kids more than adults due to higher concentrations of polluted air in their systems per body size. India is the country with the worst air quality in the world. Another direct effect is the immediate alterations that the world is witnessing due to global warming with increase in sea levels and melting of ice from colder regions and icebergs, displacements and loss of habitat have already signaled an impending disaster if actions for preservation and normalization aren’t undertaken soon.
