Document Summary
Impact (i)= population (p) x affluence (a) x technology (t) I=people x economic activity/people x environmental impact/economic activity: solid waste generation. Many countries with low gnp have low production of waste, countries with higher gnp produce more weight: switzerland is an exception to this. Population and gasoline use- as we increase our population, we use more and more gasoline: matches population growth from the babyboom. Affluence and transportation: there is a difference between the amount of energy used to transport- largest=personal trunk, lowest= bicycle. Gallons consumed = # vehicles x miles driven x gallons consumed vehicle miles driven. Population and water quality: dense populations are producing more waste than less densely populated areas, water quality disproportionality impacts lower quality income than higher quality. How have we changed the use of our environment to sustain population growth: on chart= colors show how much we have changed the environment, now we have really altered the environment.
