WebChlorofluorocarbons (CFCs) are responsible for ozone depletion. CFCs are released into the atmosphere. Then, UV rays break off chlorine. The chlorine attaches to oxygen from ozone and forms chlorine monoxide (Cl-O). The chlorine detaches and picks off another oxygen. This process can repeat 100,000 for every CFC.
