Question

Causes of thinning of ozone layer

Answer 1

Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).

Answer 2

the main reason is emission of chloroflorocarbons (cfc) .CFCs break the bond of O3 and thus results in depletion of ozone.
