NEET BIOLOGY

Detailed explanation-1: -Trees take in carbon dioxide and traps it into tissues and soil while at the same time releasing oxygen into the atmosphere. The removal of trees significantly reduces the rate of this process, resulting in higher carbon dioxide in the atmosphere and lower natural oxygen levels.

Detailed explanation-2: -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-3: -Plants take up carbon dioxide exhaled by animals and release oxygen inhaled by animals. Thus, forests maintain a balance between the two gases in atmosphere. Deforestation disturbs this balance and increases the amount of carbon dioxide in atmosphere.

Detailed explanation-4: -When forests are cut down, much of that stored carbon is released into the atmosphere again as carbon dioxide (CO2). This is how deforestation and forest degradation contribute to global warming.
