What do CFCs stand for? Name some devices where CFCs are used. Why CFCs are considered as pollutants?

CFCs stand for Chlorofluorocarbons. Chlorofluorocarbons are used in refrigerators, air conditioners and aerosol sprays.

CFCs are known as pollutants because CFCs damage the ozone layer of the atmosphere.

CFCs are broken down by the ultraviolet radiations and chlorine is produced. Chlorine then goes ahead and destroys the ozone layer.
