Multiple Choice Questions
Global warming can be controlled by

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

Answer 1

The correct option is B Reducing deforestation, cutting down use of fossil fuel

Global warming refers to the increase in the average temperature of earth due to an excessive amount of greenhouse gases namely CO${}_2$, CH${}_4$ etc. It can be controlled by reducing deforestation. A high plant cover utilizes the major amount of CO${}_2$ from the air. Also another method of control is cutting down the use of fossil fuels which otherwise emits greenhouse gases like CO${}_2$, N${}_2$O etc.

So, the correct answer is option B, reducing deforestation, cutting down use of fossil fuel.
