Air Pollution Earth is the only place in the universe that can support human life. It is very important that we realize this fact and take very good care of it. Various human activities cause the destruction of earth. Human beings can live a few days without food and water however humans can last only a few seconds without oxygen. Various human activities lead to the aggravation of the quality of air.

I will be using both these externalities in my following discussion on pollution. Companies pollute on three different platforms: air‚ water and land. Air pollution is caused by: • Factories • Power plants • Vehicles • Solvents • Domestic/industrial chemicals • Military

Causes of air pollution There are many different chemical substances that contribute to air pollution. These chemicals come from a variety of sources. Among the many types of air pollutants are nitrogen oxides‚ carbon monoxides‚ and organic compounds that can evaporate and enter the atmosphere. Air pollutants have sources that are both natural and human. Now‚ humans contribute substantially more to the air pollution problem. Forest fires‚ volcanic eruptions‚ wind erosion‚ pollen dispersal‚

EFFECTS OF POLLUTION ON THE ENVIRONMENT What is environmental pollution ? Nature maintains a balance in the environment and any kind of imbalance therein is called environmental pollution. Man’s quest to conquer the universe with technological development has resulted in grave dangers to the very existence of life on this planet. Waters are no longer clean‚ fishes are rotting on sea-shores‚ trees are withering‚ cities are choked with foul air and toxic chemicals are finding their way into our food
