Which of the following defines the effect of deforestation on environment?

  1. Level of CO$ _2$ in the atmosphere will rise

  2. Global warming

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The deforestation greatly effects on the environment. Plants absorb CO$ _2$ from the atmosphere to perform photosynthesis. If plants are destroyed, then the level of CO$ _2$ in the atmosphere will rise. As a result, CO$ _2$ will trap more heat radiations, thereby adding to global warming. An increase in the temperature of the Earth will disturb the natural water cycle. As a result, there will be a change in the rainfall pattern. This could lead to floods or droughts.

So, the correct answer is option C.
