What is the full form of CFC? Why are they harmful for the environment? What measures can we take to solve the problem?
Chlorofluorocarbons
The full form of CFC is Chlorofluorocarbons. They are harmful for the environment because they degrade ozone layer of the earth . Because CFC our ozone layer is depleting. There is a growing concern over ozone depletion and its dangers , and a ban was imposed on the use of CFC’s in aerosol-spray dispensers in the late 1970’s by United States, Canada and the Scandinavian countries. In 1990 , 93 nations agreed , as past of the Montreal Protocol, to end production of ozone depleting chemicals by the end of the 20th century . In 1992, the number has increased to 140, and the time table for ending the production of CFC’s advanced to 1996. Their goal has largely met. We can use HFC’s they pose a less risk that CFC’s because they decompose readily in the atmosphere.
