Air Pollution

Air pollution is said to be one of the major

environmental problems that is present in both developed and

developing countries. Nations have been trying to reduce the

amount of the air pollutants; nevertheless, it is an inevitable

problem in a world where people are highly dependent on

industries. Air pollution is the contamination of air by smoke

and harmful gases, mainly oxides of carbon, sulfur, and

nitrogen. This takes a huge toll on human health, and the

surrounding environment.

Some pollutants that contribute to air pollution are: carbon dioxide, nitrogen dioxide and

sulfur dioxide. They are emitted into air by cars, planes, power plants, burning of fossil fuels,

livestocks, and so on. Air pollution is classified into indoor and outdoor air pollution. Most of us

are aware of outdoor air pollution and it’s harmful effects, but are not aware of the seriousness of

indoor air pollution, affecting one half of the world’s population, especially in countries such as

Africa and South Asia. Indoor pollution is mainly caused by the use of primitive cooking stoves

such as charcoal or wood stoves. Indoor air pollution kills more people a year than outdoor

pollution does; more than three billion people depend on these household products, which

exposes them to highly toxic chemical, making them vulnerable to severe health problems.

Air pollution can be classified into two major types: natural pollution, and pollution that

is caused by humans.
