Destruction Of Ozone ( Ozone Depletion)

Ozone is layer of oxygen found in the upper layer of atmosphere (stratosphere) to protect Earth from the harm full effects of ultraviolet radiation.  Ozone consist of 3 oxygen molecules rather than 2 and it is highly .But its presence in the troposphere (the lower layer of atmosphere) causes effects to human and plants living on the earth in the form of diseases due to its highly oxidizing ability.

How ozone is produced:

Ozone is formed in atmosphere by the reaction of ultraviolet radiation with the oxygen molecule that comprises 21% of the atmosphere. The ultraviolet radiation entering the atmosphere breaks apart the oxygen molecules (O2) to produce two oxygen atoms. These single highly reactive oxygen atoms then combine separately with the oxygen molecules to make the ozone (O3) molecules. This reaction take places in the stratosphere where there are continuously ultraviolet radiation coming in. Ozone reacts with the sunlight and hazardous human produces hydro carbons and nitrogen gases continuously, resulting in the production of and destruction of ozone layers. In troposphere region, ozone is produces by the reaction of pollutant gases and natural gases with ozone in the presence of sunlight. The burning of fossils fuels contribute a lot in the production of ozone troposphere. The ozone produces in comparatively quite much less as compared to the ozone prepared in stratosphere and also can’t reach to the stratosphere to meet the need of ozone required there the plants and  the troposphere ozone is also destroyed when it reacts chemically with soil and plant on the surface  of earth

 

Effects of ozone depletion:

Since the advent of universe, the ozone has been protecting the earth from the harm full radiation of UV rays. It has become the great concern by the scientist and environmentalist since 1970. Ozone layer is depleted by the harmful gases .chlorine and bromine gases destroy the ozone layer in the upper stratosphere. But 80 percent of the ozone layer is destroyed by the chlorofluorocarbons emitted from the human made gas emitting sources.  The   chlorofluorocarbon sand   volatile organic gases that are released from refrigerators and other vehicles factories destroys the ozone layer.  These gases remain stable in the lower atmosphere of air but when they reach the stratosphere. They react with the harmful ultra violet rays and emit the chlorine atom that reacts with the ozone oxygen causing the depletion of ozone layer.

Effects of ozone depletion:

Breakage of ozone layer has adverse effects on the environment.  Depletion of ozone layer provides the path to ultraviolet rays to reach the earth, the ultraviolet rays is interlinked to cause various health and environmental issues.  Direct exposure of Ultraviolet rays cause several type of skin and eye diseases. The radiation accelerates the skin aging problem. It weakens the human immune system. UV rays damages the other amphibian species UV is home how responsible in decline of the number of amphibian species on the earth. UV destroys the plankton's that are essential to maintain the food chain and carbon cycle of marine ecosystem.

Decrease of ozone in stratosphere cause the increase of ozone in the troposphere. Ozone gas present in stratosphere is referred as green gas that causes the temperature of earth to rise and cause the climate to change.
