In recent decades, average global temperatures have increased significantly. Scientists agree that the widespread destruction of the Amazon rain forest contributes to climate change. Which mechanism might be cited to support that hypothesis? A Deforestation causes water on the ground to reflect sunlight.

B Deforestation reduces the number of plants able to absorb carbon dioxide.

C Photosynthesis produces energy, which gives off heat.

D Plants use up energy during cellular respiration.

The main reason causing average global temperature rise is increase in amount of green house gases like Carbodioxide, and since deforestation reduces a vast number of plants, so there is lack of plants absorbing CO2 causing this whole thing.

So, according to this the Correct choice is B

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.
