Question
Quote some instances where human intervention saved the forest from destruction.
✓
Answer
There have been enough instances of local people working traditionally for conservation of forests, For example:
- Bishnoi community in Rajasthan for whom conservation of forest and wildlife has been a religious tenet.
- The Chipko Andolan (‘Hug the Trees Movement’) which started in Reni village in Garhwal and, spreaded quickly among communities. In this movement, woman used to clasp the trees trunk to prevent their felling. These communities traditionally lop the branches and pluck the leaves, allowing the resources to replenish overtime.
- The sal forests of Arabari (in West Bengal) were saved from degradation with the active and willing participation of the local community. The villagers were given employment in both silviculture and harvesting operations (25% of the final harvest) and allowed for the collection of forest produce on payment of a nominal fee.

The human body has an organ A which acts as a double pump. The oxygenated blood coming from the lungs through a blood vessel B enters the upper left chamber C of the double pump. When chamber C contracts, then blood goes into lower left chamber D. The contraction of chamber D forces the blood to go into a blood vessel E which supplies oxygenated blood to all the organs of the body (except the lungs). The deoxygenated blood coming out of the body organs is taken by a blood vessel F to the right upper chamber G of pumping organ. Contraction of chamber G forces the deoxygenated blood into right lower chamber H. And finally the contraction of chamber H sends the deoxygenated blood into lungs through a blood vessel I.
