Question 3: We saw in this chapter that there are four main stakeholders when it comes to forests and wildlife. Which among these should have the authority to decide the management of forest produce? Why do you think so?
Answer: The forest dwellers should have the authority to decide the management of forest produces. There are various reasons for this. Some of them are discussed here. Forest dwellers have traditionally been dependent on forests for their livelihood. They have learnt to respect the forest and always desist from overexploitation of resources. They have some traditional knowledge which can really help in forest conservation.
Question 4: How can you as an individual contribute or make a difference to the management of (a) forests and wildlife, (b) water resources and (c) coal and petroleum?
Answer: For forests and wildlife; I can contribute by reducing the use of paper. This would help in minimizing the need for cutting down trees.
For water resources; I can contribute by preventing the wastage of water as and when possible.
For coal and petroleum; I can contribute by using my bicycle for going to school. I can also take out awareness campaigns to educate people about the benefits of using environment-friendly modes of transport.
Question 5: What can you as an individual do to reduce your consumption of the various natural resources?
Answer: I can do following to reduce my consumption of various natural resources:
