Our atmosphere consists of many layers one such layer is the ozone layer this layer protects all the living beings from the harmful ultraviolet rays of the sun. The chemical formula of ozone is O<sub>3</sub>, When the UV radiation of the sun interacts with the molecular oxygen (O<sub>2</sub>) it splits some of them into free oxygen atoms (O) these free oxygen atoms react with the molecular oxygen to form ozone (O<sub>3</sub>) and thus build a layer of protection on us. But recently due to over pollution on the earth’s surface caused due to various human activities a hole has been observed above the continent Antarctica, this in turn lets the harmful ultraviolet rays of the sun to reach the Earth’s surface and thus is causing many fatal skin problems including the life taking skin cancer.
The depletion of the ozone layer is an issue of outmost concern, and it is found that the element which is primely there behind this is CFC (Chloro Fluro Carbon), CFC molecules are emitted from refrigerators and Air- conditioners which are used in every house these days, also it is present in various sprays which we use on a regular basis. The increase in the number of such products will result in more depletion and thus would result in a dangerous situation. Its high time for us to replace these machineries with other technology.
