Document Summary
Population: growth rate: over the past 8,000 years, world population has been undergoing exponential growth. The population was increasing faster and faster: the world growth rate has been declining from a peak of 2. 2% per year in 1962 and 1963. This trend reflects the declining population in developed nations. Growth rates in poor countries in africa, asia, and latin america remain above. It is the maximum number of humans who can survive given the continued availability of food, clean water, clean air, and energy. Population that exceeds the carrying capacity of an area or environment is said to be overpopulated. If the carrying-capacity population is reached, the quality of life would be extremely unpleasant. On average, all of us will be near starvation, receiving the minimum food needed to stay alive. The atmosphere would be so contaminated that life spans would be extremely short.
