Answer: C) Increased global temperature because of the release of CO2 (carbon dioxide)
Explanation:
Trees require carbon dioxide for photosynthesis and with tropical rain forests comprising of so much vegetation, they take up a lot of carbon dioxide and store it.
When these trees are cut down and then burnt (as is the case in slash-and-burn agriculture), the stored carbon dioxide is released into the atmosphere where they block heat from leaving the atmosphere thereby creating a greenhouse effect that will increase global temperature.
