Question

Fuel wood crisis can be overcome by
A. Better wooden stoves
B. Efficient wood extraction
C. Greater afforestation
D. Using alternate energy source

Answer 1

Hint: Fuel wood crisis was seen in 1980. In this it was seen that over 200 million people were dependent on wood for cooking and heating but only half of the population was able to meet the requirements.

Complete Answer:
To solve this question, we must know about the crisis of wood and how it can be overcome.
Wood is used as a cheap source of energy all over the world. It is a renewable source of energy and is readily available from the forest.

Causes of wood crisis:
- Increase in demand due to increase in population.
- Cutting of forest
- Urbanisation.

Burning of wood causes smoke and thereby causes air pollution. So in order to curb the crises usage of wood can be minimised by using alternate sources of fuel. Use of efficient wood stoves or extracting wood efficiently cannot help in controlling fuel crises but lead to global warming and pollution.

Step taken to curb crises are:
- Use of non-renewable resources like solar energy so that the demand of wood is minimised as these energy sources are never going to get over and also causes less pollution.
- Greater Afforestation will help in preventing soil erosion and maintain the ecological balance by bringing rains and cooling the environment.

The correct answer is (D).

Note: Wood is an efficient fuel. It is obtained from the stem of the trees. It is used for cooking, heating, and also to generate electricity. It is the largest source of energy.
