Q.Why elephants and other wild animals are entering into human living area?

Life on Earth is spread across almost every habitat that exists, from permanently frozen polar ice to the scalding water around volcanic hot springs, and from shallow coastal lagoons to the deepest ocean trenches. Wherever an environment can sustain any chemistry at all, some organism has usually adapted to live there — a phenomenon biologists call ecological diversity.

Of animals alone, roughly 8.7 million species are estimated to exist, and only a modest fraction of these have actually been formally identified, named, described and classified. Large-scale surveys suggest that about 86% of land species and 91% of marine species remain completely undiscovered, which means the true scale of animal diversity is still mostly unknown even today. New species continue to turn up regularly — for example, in 2016 alone, India recorded 258 newly discovered invertebrate species and 55 new vertebrate species, spanning insects, fishes, amphibians, flatworms (Platyhelminthes), crustaceans and reptiles. …
