OBJECTIVE FORESTRY

Detailed explanation-1: -As trees, plants use carbon dioxide for the photosynthesis process, they act as a carbon reservoir. But the deforestation leads to the clearing of forests which directly impacts carbon dioxide intake from the atmosphere. This, in turn, results in the warming of the atmosphere.

Detailed explanation-2: -Deforestation can result in more carbon dioxide being released into the atmosphere. That is because trees take in carbon dioxide from the air for photosynthesis, and carbon is locked chemically in their wood. When trees are burned, this carbon returns to the atmosphere as carbon dioxide.

Detailed explanation-3: -Plants and trees perform the function of taking in carbon dioxide and give out oxygen. As the number of plants and trees reduce the carbon dioxide in the air increases and this is a major pollutant, so cutting of trees (deforestation) is a cause of pollution.
