   this system for our own existence.
2. Assertion : Neglect of our environment has led to the

   reason of destruction of species.
   Ans : (a) Both assertion and reason are true and
   reason is the correct explanation of assertion.
   Vanishing forests are the major reason for the extinction
   of species of animals and plant life. Thus, neglecting
   our environment has led to dire consequences.

   Reason : Forests are vital for the quality of life and
   environment.
   Ans : (a) Both assertion and reason are true and
