Solution:Ozone is formed by three molecules of oxygen and it is a deadly poisonous gas.Ozone layer is present in the stratosphere.The damage to the ozone layer is a cause for concern because the ozone layer protects our earth from harmful ultraviolet radiation (UV) from the sun.This harmful radiation is responsible for causing skin cancer and eye infections in humans.UV radiations not only affect humans but also other animals and plants.In humans,this harmful radiation also alters the structure of DNA and this results in mutations in DNA.
Formation of ozone
The UV radiation having higher energy divides molecular oxygen (O2) into two free oxygen (O) atoms.These free oxygen atoms combine with molecular oxygen atoms to form ozone(O3).
Steps to minimise damage of ozone layer
Avoid the use of substances that contain chlorofluorocarbons.
Introduction of environmentally friendly substances instead of chlorofluorocarbons
Avoid emission of greenhouse gases like carbon dioxide,methane
Stop burning of fossil fuels
Use CNG in vehicles
Avoid use of heavy chemicals
