Greenhouse Effect

The Greenhouse effect is one of the major threats today to our ecology and environment. When the rays of sun enter a glass enclousre, they get trapped inside it and are unable to come out. This tapping of sun's energy is called as the Greenhouse Effect.

Greenhouse effect essentially means saturation of hydrofluoric carbons in the atmosphere. These hydrofluoric carbons are emitted by freon gas used in refrigeration and air conditioning or ammonia chloride in cold storage houses.

The direct effect of Greenhouse gases is to create ozone holes in the ozone layer around the earth, which prevents harmful infrared and other ultra violet rays from reaching the earth's surface. Ozone hole is created when the ozone layer over a particular area is converted into oxygen. This will increase temperature of earth's surface apart from harming human beings and animals with radiation and the ice caps around north and south poles will melt increasing sea levels everywhere. This may submerge many islands and coastal areas. Greenhouse effect thus poses a great threat to humanity and many countries have passed laws to restrict use of hydrofluoric carbons.
