Anthropocentric: focused on human well-being: no direct concern for nature, including other animals. 6(cid:1004)% of (cid:862)e(cid:272)os(cid:455)ste(cid:373) se(cid:396)(cid:448)i(cid:272)es(cid:863) (cid:271)ei(cid:374)g deg(cid:396)aded o(cid:396) used u(cid:374)sustai(cid:374)a(cid:271)l(cid:455: e. g. fresh water, fisheries, air & water purification.

Effects of ecosystem degradations often shifted onto other groups of people, including future generations. Fresh water impounded behind dams has quadrupled: total waters in reservoirs = 3-6x water in natural areas. Last 250 years, co2 in atmosphere increased 32: majority of increase since 1960, combustion of fossil fuels + land use changes, global climate change, a severe set of problems. The distribution of species on earth is becoming more homogenous more alike in different areas, due to species introductions.
