Ans.

1. Deforestation or cutting of trees affecting the eco system in many ways. It is responsible for climatic change.

4. What is Wildlife Sanctuary? How is it different from National Park?
Ans.

1. A wildlife sanctuary is like a national park but the difference is that in a sanctuary certain types of activates might be permitted. Livestock grazing and collection of forest produce, for instance, may be allowed.
2. In a national park, conservation of species is mostly left to nature, with the least human activities, but in a sanctuary conservation of species is affected by manipulative management.

5. What are Biosphere Reserves?
Ans.

1. Biosphere Reserves are multipurpose protected areas created to deal with the issue of conservation of bio-diversity and sustainable use.

Ans.

13. Do you agree that natural vegetation is important for the environment as well as for the human beings? Give reasons to support your answer.
Ans. Natural vegetation is very important for the environment as well as for human life. So, it is very essential to conserve it. The main reasons for the importance of natural vegetation are following:

Ans.

1. It preserves ecological diversity that why there is a need to conserve our forests and wildlife.
2. It preserves our life support system-water, air soil that why there is a need to conserve our forests and wildlife.
