Answer: Forests play a vital role in the life of the human beings and in their absence we can’t imagine life. Plants release oxygen that we breathe and absorb carbon dioxide. The roots of the plants bind the soil and in this way check soil erosion. We get several things from the forests, such as wood for furniture, fuel, fodder, medicinal herbs, honey, lac, gum, fruits etc.Forests provide natural habitat to the wildlife, such as lions, tigers, elephants, monkeys, etc.As forests are so beneficial for us, we must make efforts to conserve it.

Question: What should we do to conserve wildlife?

Answer: We must not involve in hunting and poaching of wild animals. We can refuse to buy things made from parts of the bodies of animals such as their bones, horns, fur, skins and feathers. It will be an effective way to conserve wildlife. We should participate in the wildlife week which falls in the first week of October and try to create awareness of conserving the habitats of the animal kingdom.
