air pollution takes many different forms and arises from a variety of sources. In terms of overall range and extents of impacts, Many forms of air pollution are human-made.And even around the world, where it affects everything.

           burning of fossil fuels (coal, gasoline, etc..) is the single largest source of air pollutants. These fuels cause smog, acid rain, soot and particulates increases, greenhouse gas emissions, and dispersal of some heavy metal contaminants. 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, varnish, and other solvents.Factories, in general, are associated with manufacturing products, and many times that requires using many different materials in the creative process. As chemicals, heat and waste from the new products go through assembly, they all need to be removed from the factory. Open air vents, smokestacks and chimneys release the pollution from the factory into the air. burning of agriculture and livestock contribute to air pollution by releasing dangerous gases and chemicals into the atmosphere. 
    
           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 respiratory and cardiac conditions. These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and premature death. hydrogen and carbon dioxide are the main greenhouse gas. However, hydrogen is not emitted during industrial processes. Humans do not contribute to the hydrogen amount in the air, this is only changing naturally during the hydrological cycle, and as a result it is not a cause of global warming.Increasing carbon dioxide emissions cause about 50-60% of the global warming.



          The Clean Air Act, if strictly enforced by the government, will surely help 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 help curb the worsening air pollution that our mother Earth is experiencing now. There are so many ways that we could help prevent air pollution from reaching its worst level. At home and at work, turn off the lights when not needed; change the light bulbs into low power ratings with high efficiency; buy air-conditioning and refrigeration units using refrigerant, which emits limited CFCs into our air; dispose old appliances or household materials with aerosols properly; 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, and the list goes on.



     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.
