Conservation Ecology I. Introduction: a. Terms: i. Endangered: in danger of extinction over most or all of a species’ range. ii. Threatened: likely to become endangered (in danger of endangerment?) b. Why not let species go extinct? i. We use many species’ for food, clothing, medicine, etc. ii. Do we have the right to kill off species as humans? iii. Humans use/need intact ecosystems. 1. E.g. watersheds providing water for cities. If you mess up the watershed, the city won’t have water. c.
