Question

How would increased chlorofluorocarbons (CFCs) in the atmosphere affect the growth of vegetation throughout the world?

Answer 1

Chlorofluorocarbons are a class of organic compounds that were used as propellants in the late 20th century. The problem with CFC's is that they attack the ozone layer, breaking it down. The weakened ozone layer is not able to stop UV light from reaching the earth, so the amount of UV light reaching the earth increases. This results in increased temperatures, and the death of vegetation.

Therefore, the answer is B.

Answer 2

Ultraviolet light will increase on earth's surface. It will "raise" temperatures and decrease plant populations. Actually UV rays do not increase temperature, that's wrong.

They cause mutations in several organisms as they modify their DNA. They also cause skin cancer in humans and also cataracts and sunburns.

But they don't increase temperature. That's carbon dioxide accumulation.
