What is the Greenhouse Effect? It is the gradual warming of the air surrounding the earth as a result of heat being trapped by environmental pollution. This is exemplified by the destruction and burning down of tropical rain forests, by traffic that clogs up city streets, by the rapid growth of industries, the use of chlorofluorocarbons (CFCs) in packaging and manufacturing commercial products, the use of detergents such as washing powder and so on. The oceans are also said to be affected both because of human wastes and because of pollution caused by industrial wastes, oil seeping from damaged supertankers etc.

However, the main pollutant is carbon dioxide gas produced by the burning of fossil fuels and forests, and pollutants such as methane and chlorofluorocarbons. It has many bad impacts.
