SummaryPopulations and ways of sustaining them are not in balance, and the trend is toward greater imbalance rather than equilibrium.Malthusian think the population is increasing in a geometrical rate ,while substance increases in a arithmetical rate.Nature will reestablish a balance between resources and population numbers.Malthus wrote from the standpoint of the propertied class.He had a low opinion of the “l(fā)ower classes”, and his essay is full of expressions of disdain and opprobium toward the poor.Some of Malthus’s hypothesis is correct ,some are still remained teste.However, Ester Boserup argued that population determines agricultural methods, she think “necessity is the mother of invention”, humans would always find ways to support themselves.Allan have many ideas agree with Boserup, He devised a method of determining how many historical changes:stage1:high birth rate and high death rate,and low population growth.Stage2:high birth rate, low death rate, high population growth.stage3:low birth rate, flow death rate, low population growth.Japan has passed through the demographic transition.By 1966, many African countries were in stage1 of the demographic transition, A few were entering stage2.By 1993, many African countries finished stage1 ,and moved to stage2, only a few countries seemed to on the way to completing a transition or had essentially completed the demographic transition.The third stage of the demographic transition were occurring in many parts of the third world in 1993, but not in Africa.As the improvement of the technology and the economy can in turn carry the society through the demographic transition, so Commoner think the population problem lies in poverty, and its solution lies in the redistribution of wealth.In order to avoid a Malthusian Destiny, Harvey thinks the population-resource equation can be moved in the direction of equilibrium by changing any of four constituent parts of equation.In many less developed countries, a large family increase the amount of labor available for farming and the household economy.If one can guarantee the continuation of one’s family line and be secured in old age, the will limit the number of children one brings into the world.Many factors contribute to the achievement of the demographic transition, and literacy is worth further security.Literacy is one of civilization’s central tools, and the illiterate rate between man and women is different, the gab between man and women has increased narrowed somewhat.
