What fraction of the fossil fuel emissions in the united states could be absorbed by converting 25% of agricultural land in the u. s. to native forests? a. approximately 10% b. approximately 20% c. approximately 30% d. approximately 40%

Correct B). Approximately 20%

The largest source of greenhouse emission is from human activities by the burning of fossil fuel for the purpose of transportation, heat and electricity generation. About 20% of this emission is made to absorb by converting 25% of agricultural land to native forest in the U.S.

Forest are able to absorb the huge amount of released carbon dioxide that is released by the burning of fossil fuel. Thus replacing agricultural land with native forest would be of great advantage.

Hence, the correct answer would be option B.
