Tiger is one of the key wildlife endangered species. In 1973 the authorities realised that the tiger population had come down substantially. The major threats to tiger population are -

=> Poaching for trade

=> Shrinking habitat

=> Growing human population

=> Depletion of prey species.

=> Sariska Wildlife Sanctuary (Rajasthan)      

Question.8: Why do we need to conserve our forests and wild life resources ? Explain any three reasons.

Answer: There has been a rapid decline in forests and wild life population especially during the last century. Conservation of forests and wild life resources are necessary because of numerous reasons. The three most important reasons are explained below:

1. Conservation maintains the ecological balance - Forests play a significant role in balancing the ecological system since they are the primary producers on which all other living beings depend. Depletion of forests accelerates soil erosion, affects flow of ground water, causes floods, and disappearance of wildlife etc.

2. They provide economic benefits - Animals provide us valuable food products like - milk, egg, and raw materials such as wool, hides and skins. Forest products provide livelihood for many communities, also fuel and medicinal sources. Plants re-create the air we breathe.

3. Conservation is needed to protect wildlife as it is threatened by human intervention - Human beings depend on biodiversity for their very survival. Diverse activities due to growing human population have continuously eroded the wildlife habitat.     

Question.9: Explain the importance of flora and fauna in our daily life.

Answer: Flora and fauna an important role in our daily life because they purify the air we breathe, the water we drink, and enriches the soil that supports our agriculture without which we cannot survive.
