Chlorofluorocarbons (CFCs) are synthetic chemicals that were widely used as refrigerants, aerosols, and foaming agents. When released into the atmosphere, they rise to the stratosphere where UV radiation breaks them down, releasing chlorine atoms. These chlorine atoms then catalytically destroy ozone molecules, leading to the depletion of the stratospheric ozone layer, which protects Earth from harmful UV radiation.
