NEET BIOLOGY

Detailed explanation-1: -When humans cut down forests, more greenhouse gas emissions from industrial agriculture remain in the atmosphere, further contributing to the climate crisis. Humans can survive without factory farms, but we can’t survive without healthy, breathable air.

Detailed explanation-2: -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.

Detailed explanation-3: -Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.

Detailed explanation-4: -Tropical forests move more water than any other ecosystem on land, turning soil water into moisture in the air, cooling the atmosphere above them. Deforestation causes increases in temperatures and changes in the amount and distribution of rainfall-generally creating a drier climate.

Detailed explanation-5: -When deforestation occurs, much of the carbon stored by trees is released back into the atmosphere as carbon dioxide, which contributes to climate change.
