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.
