Deforestation
a. diminishes the trees' ability to purify water
b. increases greenhouse gases
c. fosters replication of endangered species
d. increases the availability of resources to humans
e. minimizes the flow of water, but increases the quality of the water we drink

Option B

Explanation:

Deforestation can be defined as the cutting down of trees in huge number. This act increases the amount of green house gases in the environment.

This is so because the carbon dioxide which is an important green house gas is absorbed by the trees which reduces the concentration of green house gas and thus decreases green house effect.

But lesser number of plants will increase the amount of carbon dioxide in the atmosphere thus increasing the green house effect.
