Briefly explain depletion of ozone layer and its effects.
Ozone molecules form when a single O atm reacts with oxygen O2 molecule.
Chlorine containing compounds are major reason for the corrosion of ozone layer. Chlorofluorocarbons and certain other ozone depleting substances that contain chlorine and/or bromine are responsible for depletion of ozone layer. CFCs are made of chlorine. One single atom of chlorine destroys 1000 molecules of ozone.
Effects of ozone depletion are-
● More skin cancer in humans due to ultraviolet radiations which will easily reach the skin cells through stratosphere if ozone layer depletes.
● UV radiations would also damage parts of eyes thus causing cataracts, blindness and other diseases.
● Immunosuppression- UV radiations could damage the immune system.
