Question

Which of the following is not a preventive measure of ozone depletion?

• A. Replacement of CFCs with alternative such as HFCs and HCFCs
• B. Using alternative source of energy instead of fossil fuels
• C. Using chlorinated insecticides and pesticides instead of biopesticides and bioinsecticides
• D. Banning of harmful ozone depleting substances

Answer 1

The correct option is C Using chlorinated insecticides and pesticides instead of biopesticides and bioinsecticides

Using chlorinated insecticides and pesticides contributes to the depletion of ozone as when they break down, they release chlorine into the atmosphere, which attacks the ozone molecule. The use of eco- friendly biopesticides and bioinsecticides minimize the negative effects of these chemicals.
