Biodiversity: the value of wild species and biodiversity. Ecosystem capital: all goods and services provided to humans by natural systems. The basis of ecosystem capital = ecosystems: the basis of ecosystems = wild species. To maintain ecosystem sustainability, you must save ecosystem integrity, resilience, processes, biodiversity: natural biota have recreational, aesthetic, and scientific value, biological wealth. 2 million species have been examined, named, classified: out of 5-30 million species. Biodiversity: richness of living species: the value of wildlife. Instrumental value: a species(cid:495) or organism(cid:495)s existence or use benefits some other entity: food, shelter, source of income, usually anthropocentric: beneficiaries are humans. Many people believe only humans have intrinsic value: species have value as sources for materials. Most food comes from agriculture: wild populations have traits for competitiveness, resistance to parasites, tolerance to adverse conditions, agricultural populations have lost these traits.
