What are CFCs? what are the adverse effects of CFCs?

CFCs or Chlorofluorocarbons:

• CFCs stand for chlorofluorocarbons.
• Chlorofluorocarbons (CFCs) arc non-toxic, non-flammable chemicals containing atoms of carbon, chlorine, and fluorine.
• CFCs react with sunlight in the earth's stratosphere to break down the protective ozone layer, a layer of gas that shields the earth's surface from damaging UV rays.
• Chlorofluorocarbons used in aerosols, refrigerators, and air conditioners cause the depletion of the ozone layer in the atmosphere.
