Question

Quizplus · Accepted Answer

Methane emissions from the digestive systems of ruminants, rice cultivation, and decaying wetland vegetation are all significant sources of methane emissions. Automobile exhaust, on the other hand, is a source of carbon dioxide emissions, not methane. Therefore, choice D (i, iii, and iv only) is the best answer.

Methane Is Approximately 23 Times More Powerful Than Carbon Dioxide
