Although both humans and nature cause this corrosive precipitation, approximately what proportion of acid rain is attributable to humans?

a.) 1/4
b.) 1/2
c.) 2/3
d.) 3/4

The correct answer would be option C. Approximately 2/3 is the proportion of acid rain that is attributable to humans. Acid rain is a rain or any other form of precipitation that is acidic. The principal natural cause that produces gases that contributes to acid rain is emitted from volcanoes. This consists 1/3 of the proportion that contributes to acid rain and 2/3 from human activities.

The answer would be dogs.
