Endangered Animal Facts

Congress passed the Endangered Species Act in 1973 to protect animals that were in danger of becoming extinct. The U.S Fish and Wildlife Service has the task and responsibility of maintaining the list of endangered animals.

Significance

As of July 2009, there were nearly 1,900 animal species listed as endangered or threatened worldwide, including more than 1,300 found partly or entirely in the U.S., according to the National Oceanic and and Atmospheric Administration.

From A to Z

From the American bison, to the great white whale, to the zebra, endangered animals are small, big, dangerous and harmless.

Desruction of Habitat

Animals become endangered when humans destroy their natural habitat. Homes, shopping centers, highways, golf courses and airports have taken over the habitats of many endangered species.

Pollution

Pollution is a main component in placing animals on the endangered list. Oil spills, acid rain, litter and water pollution have put many animals at risk.

Hunting and Fishing

Hunting and fishing have endangered much wildlife. Sought after for food, fur, leather or other valuable assets, many animals have become over-hunted and caught.

Disease

Some disease carried by both humans and other animals can put animals in danger. Exotic species can both carry and be afflicted by diseases they cannot fight.
