Green house affect and environmental degradation. The World society is facing today an ecological crisis.

Green house effect is a major problem in ecology and environment. The rays of sun, when enter a glass enclosure, they get trapped inside it and are unable to come out. Trapping of sun energy by this process is called as the greenhouse effect. In nature we observe the trapping of sun’s energy between the earth surface and the surrounding atmosphere. There is thus a greenhouse effect in nature also. It is gases like chloro-fluro
Carbons and carbon dioxide present in the atmosphere, which are responsible for the greenhouse effect. Greenhouse effect essentially means saturation of hydrochloric carbons in the atmosphere. Hydrochloric 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 happens 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 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 hydrochloric carbons. Environmental degradation is the degradation of the environmental through depletion of resources such as air, water and soil, the destruction of ecosystems and the extinction of wildlife. Global warming is the observed increase in the average temperature of the earth’s atmosphere and oceans in recent decades and its projected continuation into the future. Acid rain occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere, undergo chemical transformations and are absorbed by water droplets in the clouds. Acid rain kill fish, and it can slow the growth of forests, cause leaves and needless to turn brown and fall off and die. Soil biology can be seriously damaged by acid rain. Greenhouse effect is a major problem for human beings. But we need to control the greenhouse effect and we must have to decrease all the causes of greenhouse effect for future generation and for the present generation also. If we don’t try to maintenance for ecological balance and keeping for environmental balance, otherwise human societies bound to decline very soon. So the world societies have to take the problems in ecology and environment as a challenge to keep the world less affected by greenhouse gases. So we have to take oath as to keep this world green and within ecological balance, and we must try to decrease greenhouse gases in this world. We have try to free from facing an ecological crisis.
