Answer:
Answer 2= The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
answer 3 =Wildlife sanctuaries and national parks are reserved forest areas which are meant to protect plant and animal species which are on the border of extinction. ...

2. Near threatened
3. Extinct in the wild
4. Least concern
5. Critically endangered

The genetic diversity of plants and animals is preserved.
It ensures the sustainable utilisation of life support systems on earth.
It provides a vast knowledge of potential use to the scientific community.
A reservoir of wild animals and plants is preserved, thus enabling them to be introduced, if need be, in the surrounding areas.
Biological diversity provides immediate benefits to the society such as recreation and tourism.
Biodiversity conservation serves as an insurance policy for the future.
