- Convention on International Trade in Endangered Species. Lists (1) some 900 species that cannot be commercially traded as live specimens or wildlife products because they are in danger of extinction and (2) restricts international trade of 29,000 other species because they are at risk of being threatened.

5 True/False questions
flyway → All free, undomesticated species. Sometimes the term is used to describe only free, undomesticated animal species.
population viability analysis (PVA) → Use of mathematical models to estimate a population's risk of extinction.
biological extinction → Species no longer found anywhere on earth; forever.
threatened species → Wild species that is still abundant in its natural range but likely to become endangered because of a decline in numbers.
intrinsic value → Value of an organism, species, ecosystem, or the earth's biodiversity based on its usefulness to us.
