How do CFCs affect ozone layer?

CFCs are manmade chemicals called chlorofluorocarbons. These substances are found in refrigerators, ACs. Etc. Due to long life and their ability that they do not wash in the rain, so they rise up into the ozone layer above the earth, where they eventually breakdown by heavy exposure to ultraviolet (UV) radiations. When CFC is broken down, it releases chlorine and bromine atoms which can destroy various ozone molecules at once. They cause the ozone layer to breakdown faster than it can replace itself.
