The definition endanger species

Endangered animals are those kind that are in danger of going to be extinct. Their reproductive rates are lower than their mortality rates over long periods of time, so their numbers are diminishing. The reasons for this are varied, but lately, very often involve a loss of habitat as people encroach on their living areas. 

 

When a species is listed as endangered or threatened, it is not a death sentence. Many animals, like the Grevy’s zebra and the Giant Panda, were on the brink of extinction and are now recovering. Many species, however, will not recover, and could be lost forever. 

 

Throughout time, animal species have been going extinct (long before people evolved); paleontologists estimate that well over 90 percent of all plant and animal species that ever existed have gone extinct
