             air pollution takes many different forms and arises from a variety of sources.it  has a series of effects on human health as well as the whole environment and it has already become a global issue.
                With rapid growth of industries and economy, air pollution becomes a worldwide problem, especially in developing countries. The quick industrialization is usually accompanied by much more factories. Burning a great deal of fuel, burning of fossil fuels (coal, gasoline, etc..) is the  largest source of air pollutants. These fuels cause smog, acid rain, soot and particulates increases, greenhouse gas emissions. Fossil fuels are widely used for heating, transportaion, electricity generation, manufacturing and other industries. Other human-made sources include aerosol sprays and leaky refrigerators, as well as fumes from paint.Burning of agriculture waste in Egypt causes a high range of pollution.


               The health effects caused by air pollutants may range from subtle biochemical and physiological changes to difficulty in breathing, wheezing, coughing and aggravation of existing .It has caused many problems ranging from lung cancer to the greenhouse effect. These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and premature death. .Increasing carbon dioxide emissions cause about 50-60% of the global warming.


           The Clean Air Act, if strictly enforced by the government, will surely  improve its clean air standard, which in turn improves human health and results in a longer life span. It is the responsibility of every individual to  fight air pollution that our  Earth is suffering from now. There are so many ways that we could help prevent air pollution from reaching its worst level. At home and at work and at everywhere, turn off the lights when not needed; change the light bulbs into low power ratings with high efficiency;walk instead of using the car when going to a place only a block away; and let your school children ride in a school bus rather than sending them to school with the family car.you shouldn't throw your garbadge in the street.The government should prevent burning of agriculture and industrial waste.


       There are plenty of ways that we can contribute in the preservation of our environment. Air pollution is an important matter, which every individual should be concerned about. The solution to air pollution is not a government concern,This is everybody's issue.
