Air pollution is the mixing of foreign substances to the whole atmospheric air. Harmful and toxic gases emitted by the industries and motor vehicles causing huge damage to the living organisms whether plants, animals or human beings. Some of the natural and various human resources are causing air pollution. However, most of the air pollution sources are stem out of the human activities like burning fossil fuels, coal and oil, release of harmful gases and substances from factories and motor vehicles. Such harmful chemical compounds like carbon dioxide, nitrogen oxides, carbon monoxide, sulphur dioxide, solid particles, etc are getting mixed to the fresh air. The level of air pollution has become increased by great extent because of 690% increase in damaging pollutants because of the expanded need of motor vehicles from last century.

Other source of the air pollution is decomposition of garbage in landfills and disposal of solid wastes which are emitting methane gas (dangerous to the health). Rapid growth of population, industrialization, increased use of automobiles, aeroplanes, etc has made this issue a serious environmental problem. The air we breathe every moment is full of pollutants going to our lungs and whole body through blood causing uncountable health problems. Polluted air is causing damage to the plants, animals and human beings in many direct and indirect ways. If the environmental protection policies are not followed seriously and strictly, the increasing level of air pollution may increase up to one million tons annually in the recent decades.

When the fresh air gets polluted by means of dust, toxic gases, smoke, motor vehicles, mills and factories, etc called air pollution. As we all know that fresh air is the most important element of the healthy life, we need to think that what happens if whole atmospheric air gets dirty. First of all air pollution is the matter of great regret for the whole human fraternity. Some of the big reasons of the air pollution are use of poisonous fertilizers, insecticides, pesticides in the agricultural sectors by the innocent farmers in order to increase the crop production. Released chemicals and hazardous gases (ammonia) from such fertilizers are getting mixed into the fresh air and causing air pollution.

Burning of fossil fuels such as coal, petroleum including other factory combustibles are the major causes of air pollution. Variety of smoke emissions from the automobiles such as cars, buses, motorcycles, trucks, jeeps, trains, aeroplanes, etc are also causing air pollution. Increasing number of industries is causing release of toxic industrial smokes and harmful gases (like carbon monoxide, organic compounds, hydrocarbons, chemicals, etc) from the factories and mills to the environment. Some indoor activities of the people like innocent use of cleaning products, washing powders, paints etc emits various toxic chemicals to the air.

The ever increasing level of air pollution also enhances its negative and harmful effects to the health of living beings. Air pollution is causing global warming to increase because of increasing atmospheric temperature due to the increasing level of green house gases. Such green house gases again causing green house effect and forcing sea levels to increase, glaciers to melt, weather to change, climate to change, etc. Increasing air pollution is causing many lethal diseases (cancer, heart attack, asthma, bronchitis, kidney diseases, etc) and death to occur. Various important animals and plants species have been destroyed completely from this planet. Increasing level of harmful gases in the environment are causing the occurrence of acid rain and depleting the ozone layer.
