The depletion of the stratospheric ozone layer is primarily a concern because the ozone layer:

A Absorbs harmful ultraviolet (UV) radiation from the sun

B Provides oxygen for human breathing

C Traps heat and causes global warming

D Reflects radio signals around the globe

Explanation. The stratospheric ozone layer absorbs most of the sun's harmful ultraviolet radiation, protecting life on Earth. Its depletion by chlorine and bromine from refrigerants increases UV exposure, raising risks of skin cancer and cataracts.
