Document Summary
Populations change in size very rapidly, and said changes are noticeable. World population size has increased rapidly since emergence of homo sapiens. Growth in human population is not continuous, but can be expressed as a geometric (exponential) curve (with drastic increase starting around industrial revolution) Impact of pop growth: destruction of lands, population, emission of waste, housing problems, decrease in food availability, decrease in job opportunities, more disease, use of non-renewable natural resources, less available space. Population size is limited by: available space, available nutrition, famine and disease, social forces, decisions of nations/families, temperature variations, oxygen levels, economics. Beneficial to have estimates of pop growth and distribution to plan for the future. Thomas robert malthus (english economist, 1766-1834) - population growth will outpace food supply growth, any uncontrolled population will deplete its food supply, was correct in stating that there are limits to earth"s capacity to supporting its people.
