  2. Extinction • Permanent loss of a species.

  3. Factors that Threaten Species • Habitat loss • Unregulated or illegal killing or collection • Pesticides and other pollution • Climate Change • Competition with other species • Disease • Predation • Invasive Species

  4. Pesticides

  5. Habitat Loss • Number one • Habitat Alteration

  6. Overhunting

  9. Threatened Species • Vulnerable (VU) • a species considered to be facing a high risk of extinction in the wild. • Endangered (EN) • a species considered to be facing a very high risk of extinction in the wild • Critically Endangered (CR) •  a species facing an extremely high risk of extinction in the wild

  10. What has been done to help this issue? • Endangered Species Preservation Act, passed in 1966 • Endangered Species Conservation Act, replaced the above legislation in 1969 to strengthen the it. • Endangered Species Act, passed in 1973 • The responsibility for the management of endangered species in terrestrial habitats falls on the Fish and Wildlife Service of the Department of the Interior.
