Document Summary
Environment: population: a root cause of environmental degradation. More is consumed that what is supposed to be. 4 ~ 7 million: first human - lucy. 58 years: in canada, growth rate (natural and net immigration together) = 0. 9% (now. 33. 5m) it will double in 75 years: in china, the population growth was 2. 8% (70 / 2. 9 years = 24 years), 1979, one child policy. Global population growth: population growth rate is exponential. (e. g. bank rate - population is being compounded in the low rate- peak in the late 60). Carrying capacity: will come to an limit. Carrying capacity uncertainty: isolated population - major drops. 4 distinct increase in carrying capacity for humans): cultural evolution: paleolithic, neolithic, industrial revolution, modern- technological revolution - now, people have moved around and taken to different places. Industrial revolution: transition from basic framing and manufacturing - massive fuel production, even in the agricultural field- tractors. Medical- technological revolution: green revolution- agricultural revolution- more food.
