due to loss of forested lands which used to be the habitats of wild elephants in the dalma hills of northern districts of west bengal in india,no. of those elephants are in a decline from 2004.most elephants die because they if mistakenly trespass into the farmlands which actually have been cultivated after destroyin gthe rainforests, they get entangled in the wires of the fences which are electrically charged and die of electrocution. sometimes, locals kill these wild elephants for coming into the civilized quarters.so actually loss of habitat does lead to extinction in a major way.
