Why is conservation of forests and wildlife necessary?

Why is conservation of forests and wildlife necessary? In what way have conservation projects changed in recent years?
Ans. Conservation of forests and wildlife is necessary formaintenance of the ecological balance. If this is disturbed, it can cause long-term damage to the environment and ecology, thus threatening even human existence. We should implement biodiversity conservation practices now to prevent future generations from suffering due to our negligence today.
Earlier the conservation projects were concentrating on particular components of biodiversity. For instance, Project tiger was started to conserve the tiger population in India.
But now-a-days there is a more intensive search for different conservation measures focussing on preservation of biodiversity as a whole. Revisions in the Wildlife Act in recent years have included insects, moths, butterflies and even plants for preservation.
