Answer 2

Ozone depletion occurs when chlorofluorocarbons (CFCs) and halos —gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). ... CFCs and halos cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity.

the consequences are as follows:

i. Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
