Question

Global warming can be controlled by

• A. Reducing deforestation, cutting down use of fossil fuel
• B. Reducing reforestation, increasing the use of fossil fuel
• C. Increasing deforestation, slowing down the growth of human population
• D. Increasing deforestation, reducing efficiency of energy usage

Answer 1

Answer: (A)

Reducing deforestation, cutting down use of fossil fuel

Deforestation is a contributor to global warming and is often cited as one of the major causes of the enhanced greenhouse effect. Tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions. Burning fossil fuels increases the amount of carbon dioxide (CO${}_2$) in the atmosphere. CO${}_2$ is a major contributor to climate change or global warming.
