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

evs - i forests: our lifeline afforestation deforestation and its effect deforestation

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

  2. Global warming

  3. Both A and B

  4. None of the above

Show answer
Correct Option: C
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.

Which of the following human activities is used to meet the ever-increasing demand in factories and for shelter?

  1. Soil erosin

  2. Pollution

  3. Deforestation

  4. Data insufficient

Show answer
Correct Option: C
Explanation:
According to a United Nations report, agriculture is the major cause of deforestation. Farming is responsible for 48% of deforestation; commercial agriculture is responsible for 32% of deforestation; logging is responsible for 14% of deforestation and fuel wood removals make up 5% of deforestation. This report shows that agriculture is responsible for 80% of deforestation. 
Since human beings also need natural resources for their use but it is our responsibility to protect the earth. This can be done by proper planning for afforestation so that removed trees can be replaced with new trees. Thus, the correct answer is option C.

Deforestation causes

evs - i forests: our lifeline afforestation deforestation and its effect deforestation

  1. Soil erosion

  2. Soil pollution

  3. Noise pollution

  4. Air pollution

Show answer
Correct Option: A
Explanation:

In India, deforestation is the main cause of soil erosion. The quality of topsoil loss in India is about 18.5% of the total global loss.

Which of the following is the cause of deforestation?

evs - i forests: our lifeline afforestation deforestation and its effect deforestation

  1. Urbanization

  2. Agricultural activities

  3. Forest fires

  4. All of the above

Show answer
Correct Option: D
Explanation:

As the population increases, the need for land also increases, forests are cleared for the construction of roads and malls and buildings. The demand of food grains also increases, so it calls for clearing more trees and growing food crops. Forest fires also cause deforestation.

So, the correct answer is option D.

Which of the following is the natural cause of deforestation?

evs - i forests: our lifeline afforestation deforestation and its effect deforestation

  1. Urbanization

  2. Forest fires

  3. Agricultural activities

  4. All of the above

Show answer
Correct Option: B
Explanation:

Forest fires are naturally caused and not man made like urbanization and agricultural activities, hence, they are the only natural cause of deforestation. Natural fires are caused by lightning, with a very small percentage started by spontaneous combustion of dry fuel such as sawdust and leaves. Human activities may also lead to forest fire.

So, the correct answer is option B.

Match the following.

   List I    List II
 i   Deforestation  a   Urbanization
 ii  Natural cause of deforestation  b  Cutting of forests
 iii  Man-made cause of deforestation  c  Droughts
evs - i forests: our lifeline afforestation deforestation and its effect deforestation

  1.  I- b, II- a, III- c

  2. I- a, II- b, III- c

  3. I- c, II- a, III- b

  4. I- b, II- c, III- a

Show answer
Correct Option: D
Explanation:

Deforestation means cutting down of forests. Droughts are natural causes of deforestation and urbanization is the man-made cause of deforestation. The most dramatic impact is a loss of habitat for millions of species. Seventy percent of Earth's land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes.

So, the correct answer is option D.
