Because of deforestation and other human activity wild animals lost their habitat and reached at risk of become extinct. Indian is losing their animals due to Environmental pollution, deforestation,loss of habitat, human interference, poaching and hunting.
Endangered species Photo by: Once extinct, a species is no longer found anywhere on Earth. Once gone, it is gone forever. However, in modern times species and their natural habitats are mostly threatened by human activities.
Humans have already caused the extinction of many species, and large numbers of many other species are currently endangered and may soon become extinct.
Causes of extinction and endangerment Most of the species that have ever lived on Earth are now extinct. Extinction and endangerment can occur naturally.
It can be the result of a catastrophic disturbance, such as the collision of an asteroid with Earth some 65 million years ago.
The impact brought about the extinction of almost 50 percent of plant species and 75 percent of animals species then living on Earth, including the dinosaurs. Disease, a change in climate, and competition between species also can result in natural extinction. The overhunting of wild animals for their hides or meat or to protect livestock and the destruction of natural habitats are the human activities most responsible.
A wave of extinctions began in North America about 11, years ago, at about the time when people first migrated across a land bridge from Siberia to present-day Alaska.
Probably within only a few centuries, species such as the mastodon, mammoth, and saber-toothed tiger had become extinct on the continent.
In modern times, overhunting has caused the extinction of such species as the dodogreat aukand passenger pigeon Infor the first time in about years, a member of the primate order the group of mammals that includes monkeys, apes, and humans became extinct.
Scientists said its extinction was brought about by overhunting and the destruction of its habitat in the rain forest canopy in the African countries of Ghana and Ivory Coast. How many endangered species are there? Scientists readily agree that the rate at which species are becoming extinct around the world is increasing rapidly.
It is hard, however, to put a figure on the actual number of endangered species. Researchers are able to document the endangerment of large and well-known animal and plant species.

Agaporomorphus colberti Wheeler & Miller, (diving beetle) Wheeler said, "Last year, Stephen shamelessly asked the science community to name something cooler than a spider to honor him. His top choices were a giant ant or a laser lion. While those would be cool species to discover, our research involves beetles, and they are 'way cooler' than a spider any .
