Answer: The depletion of the ozone layer is due to CFC (chloro fluoro carbon) which is widely used in air conditioner and refrigeration.
Step-by-step explanation:
Ozone layer prevents the harmful radiation from entering the earth's surface.
Ultraviolet radiation is very harmful radiation. Exposure of this radiation can cause Skin cancer. It is the main cause of the sunburn.
The depletion of the ozone layer is due to CFC (chloro fluoro carbon) which is widely used in air conditioner and refrigeration.
CFC is broken down by ultraviolet radiation. Then, the chlorine is released. This chlorine reacts with oxygen. In this way, it destroys the ozone molecule.
