In the stratosphere, about 30 km above the earth surface, the ozone layer molecules (O3) form an umbrella. It prevents the penetration of harmful ultra violet radiation from the sun and thus protects the life of the earth.
Ozone is odourless, invisible, that is why it is widely used in domestic refrigerators and cold storage facilities. It is calculated that the depletion of ozone layer by 1% results in an increase in the incidence of skin cancer by 5% to 7%.
