Question

Ozone depletion is caused by chlorofluorocarbons.

• A. True
• B. False

Answer 1

The correct option is A True

Aerosol spray cans and refrigerants had chlorofluorocarbons/CFCs as non-inflammable gases (which are now no more used) and were once the major cause of ozone depletion. One molecule of chlorine coming from CFCs can cause breaking up off 1 lakh molecules of ozone $\left(O_3\right)$, thus exposing living organisms from the harmful effect of UV light.
