How human activities have affected the depletion of flora and fauna ? Explain


#1

(i) Human activities like shifting agriculture, mining, grazing, fuelwood collection and construction of river valley projects like Narmada Sagar Project have led to large scale deforestation and loss of habitat of animals.
(ii) For example, the Buxa Tiger reserve in West Bengal is damaged by dolomite mining. It has disturbed the natural habitat of many species and blocked the migration of several others, including the great Indian elephant.
(iii) Clearing of forests with projects like Narmada Sagar would inundate 40,000 hectares of forest.
