Q.03:- 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?

  • people living in and around forests and dependent on forest produce for various aspects of their lives.
  • the government which owns and controls the resources of forests.
