What is Green House Effect?
The Green house effect is one of the major threats today to our ecology and environment. When the rays of sun enter a glass enclosure, they get trapped inside it and are unable to come out.
This trapping of sun’s energy is called as the Greenhouse Effect. In nature, we observe the trapping of sun’s energy between the earth’s surface and the surrounding atmosphere.
There is thus a Greenhouse Effect in nature also: It is gases like Cholosofluro carbons and carbon dioxide present in the atmosphere, that are responsible for 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 ultraviolet rays from reaching the earth’s surface. Ozone hole is created when the ozone layer over a particular area is converted into oxygen.
This happen when chlorine atoms attack ozone and take away an oxygen atom to form chlorine monoxide ozone holes. Through the holes ultraviolet rays can enter the earth.
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.
