Abstract

An endangered species is a population of organisms which is at risk of becoming extinct because it is either few in numbers, or threatened by changing environmental or predation parameters. The first criterion to conserve the biodiversity of the planet is to take into consideration the reasons why so many species are becoming endangered. ‘Habitat loss is the most widespread cause of species endangerment in the U.S., affecting 85% of imperiled species’. When an animal’s ecosystem is not maintained, they lose their home and are either forced to adapt to new surroundings or perish. Pollution is another factor that causes many species to become endangered. Also, over-exploitation, disease and climate change have led to the endangerment of several species. An endangered species is defined as a population of an organism that is at the danger of becoming extinct because of several reasons. Endangered species in India include large varieties of rare species of flora and fauna. Indian wildlife that comprises numerous species of birds, animals, mammals, etc. is well famous for being one of the richest in the world. The Indian wildlife also contains several endangered species that are living critically on the verge of extinction.
