EVR 1001 Lecture Notes - Lecture 9: Ecological Footprint, Birth Rate, Demographic Transition
Document Summary
16 out of 20 top polluted cities in the world are in china. Thomas malthus (1798) predicted that human population growth would be stunted or crash based on food production. Paul ebrlich (1968) argues that we are going to deplete all of the resources on earth with population growth. Demography: the study of human populations and population trends. Factors that drive human population growth: changes in pop size: immigration + birth; emigration + death. Crude birth rate: the number of births per 1000 individuals per year. Crude death rate: the number of deaths per 1000 people per year. Global growth- (cbr-cdr) / 10= gr percent. Doubling time: the number of years it takes a population to double. The rule of 70 can be used to estimate the dt in years; divide 70 by the growth rate. Total fertility rate: an estimate average number of children a woman will bear.
