Wildlife conservation is the practice of protecting animal species

and their habitats. It is achieved partially through legislation. For

example, the Endangered Species Act, the establishment and

protection of public lands, and responsible public practices that

conserve wild animal populations.

The Endangered Species Act (ESA)of 1973 is our nation’s

strongest law protecting wild plants and animals. It is enforced

by the U. S. Fish and Wildlife Service (USFWS)and the National

Marine Fisheries Service. Under the act, a species can be

designated as “threatened” or “endangered”. Threatened and

endangered species are protected under the provisions of the

ESA, which restricts human activities that may harm these

species and their habitats. Due in part to protections under the

ESA, many species have been brought back from the edge

of extinction.

In order to survive, a species requires enough food, water,

shelter, space, and opportunities to reproduce. In the United

States, as elsewhere in the world—habitat destruction is a

primary threat to the continued survival of species. Without the

existence of suitable habitat, a species will eventually face

extinction. Public lands include parks managed by The National

Park Service and national wildlife refuges operated by the U. S.

Fish and Wildlife Service. These lands are set aside to be

protected for animal and plant species, as well as future

generations.

The introduction of invasive species from far away continents

introduced by humans can bring havoc to native plant and

animal species. The proliferation(激增)of chemicals in the

environment including pesticides PCBs, and oil spills, has the

potential to poison wild animals and reduce their reproductive

capacities. Wild animal populations can also be threatened by

overhunting, wildlife trafficking(非法交易)，and military weapons

testing.
