17
Worth 16,000What is the aim of
captive-breeding programs.
  1. to increase the population size of species to
    double its former size.
  2. to restore the animal kingdom
  3. to restore germ plasm
  4. to restore species and release it to its natural
    habitat

18

    habitat
  • Worth 16,000

19
Worth 32,000Because of efforts by CITES
  1. the cost of ivory worldwide increased.
  2. the poaching of elephants increased.
  3. the international trade of ivory was banned
    worldwide.
  4. a captive-breeding program for elephants was
    established.

21
Worth 64,000Emphasizing the preservation of
entire ecosystems will
  1. cause the economic needs of farmers to suffer in
    order to save a single species.
  2. decrease biodiversity, especially in the tropical
    rain forests, coral reefs, and islands.
  3. cost more than identifying and preserving
    individual species.
  4. save many known and unknown species from
    extinction.

    for each endangered and threatened species.
  4. The federal government may not carry out any
    project that jeopardizes endangered species.
