A: - populations dependence on things from our environment (water, food, wood, etc. ,) Inputs to sinks; e. g. , natural resources materials, fuels emissions. 71% of earth is ocean, and only 3% of land surface can grow/cultivate food. Growing population needs more land: more land= more deforestation, fertilizers, pesticides, irrigation leading to salination, more land being used to grow bio fuels instead of crops. Destroying wildlife habitat and other essential ecosystems. 2. q: the current state of (cid:272)i(cid:448)ilizatio(cid:374) (cid:272)a(cid:374) (cid:271)e des(cid:272)ri(cid:271)ed i(cid:374) ter(cid:373)s of pro(cid:271)le(cid:373)s of (cid:858)i(cid:374)put(cid:859) or pro(cid:271)le(cid:373)s of (cid:858)output(cid:859).

A: - higher demands of water than supply (fresh) -2. 5% of water is freshwater.
