In the list of the most hazardous global environmental concerns, the problem of ozone layer depletion can be viewed as a worldwide concern since 1970s. It mainly refers to two different kinds of depletions which are correlated with each other. One is a steady decline of about 4% in the total volume of ozone in the Earth’s stratosphere which is also called as the ozone layer and the other is springtime decrease in stratospheric ozone around Earth’s Polar Regions which is of much higher level. The second phenomenon is also called as the ozone hole. Apart from these stratospheric phenomena, there are also various other springtime polar troposphere ozone depletion events.

The ozone layer forms an invisible layer of protection around the planet Earth protecting us from the harmful rays of the Sun. Depletion of the Ozone layer of the atmosphere is mainly caused due to the pollution of Chlorine and Bromide found in Chloro-floro carbons commonly referred as CFC’s. When these toxic gases reach the upper atmosphere, it makes a hole in the ozone layer. The biggest and the most threatening of such holes are above the Antarctic.

So, how to resolve this problem? The best can be done through the government of all the nations who must take strict steps to ban the usage of CFCs in industries and consumer products and protect ozone layer which prevents us from harmful UV radiations.
