Question

What is the effect of chlorofluorocarbon to the ozone layer?

Answer 1

Chlorofluorocarbons deplete the ozone layer, causing a hole in it. This allows the passage of sun's ultraviolet radiations to enter into the earth's surface which is harmful for life on earth. It causes cancer.

Answer 2

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.
