Document Summary

Higher risk traits: restricted geographic range, need large territory, low reproduction, specialized breeding habitat, specific food, compete with humans. 2 reasons we should care- instrumental value (wild species provide goods and ecosystem services), and intrinsic value (for keeping species alive) Us endangered species act of 1963- protects endangered species through close regulation study of evaluating each species, and generating recovery plan. Cons: makes land owners want to kill endangered species on their land, only focuses on popular species, no timeline, not enough. Icun (international policy)- monitors conservation efforts, maintains red list of threatened species. Cites-international agreement to halt trade of threatened + endangered species. In situ-on site conservation, done on places of rare species habitat, and location that"s a hotspot, like parks. Ex-situ- off site conservation in captivity like zoos, and do captive breeding then reintroduce into wild. Humans use 41% of earth terrestrial surface-3% urban, 38% ag.
