Document Summary
P = population (how many consumers are there ) A = affluence (how much do they consume) T = technology (how do we make what they consume) Carrying capacity: max population that can be sustained by the local environment"s resources. Ecological footprint: the theoretical spatial extent of earth"s surface required to sustain an indi. cornucopian population theorists see population as a resource, not a problem (e. g boserup 1965) More people = more brains + hands solving problems. Ignores the scale of processes like food production. Different impacts on local communities compared to distant markets. More food may be produced than needed, but it is not distributed evenly. Some innovations increased food supply but damaged other ecosystems. Growth trends moving toward zero growth rate (equal number of births and deaths, no net change in population) Some suggests development is cause declining population growth rates. Describes the growth of the human population over time.
