There are many ways that people can push wildlife populations toward extinction: destruction of habitat, pollution, hunting, and collection for food or sale to the pet, research, entertainment, or souvenir industries, etc. Fortunately, there are just as many ways that we can fight for these animals


Under the U.S. Endangered Species Act, an "endangered" species is one in danger of extinction throughout all or a significant portion of its natural habitat. A "threatened" species is one likely to become endangered in the foreseeable future.

Other federal laws protecting wild animals and their habitats include the Marine Mammal Protection Act, the Migratory Bird Treaty Act, and the Wild Bird Conservation Act. States often have laws to protect imperiled species and the United States has signed many international agreements.

The HSUS is vigilant is assuring that laws are enforced and the species protected.
