Prior to the dispersion of humans across the earth, extinction was a purely naturalphenomenon that generally occurred at a continuous low rate (mass extinctions being relatively rare events).
According to a 1998 survey of 400 biologists conducted by New York's American Museum of Natural History, nearly 70 percent of biologists believe that we are currently in the early stages of a human-caused mass extinction, known as the Holocene extinction event.
Nature preserves are created by governments as a means to provide continuing habitats to species crowded by human expansion.
