Document Summary
The first written record that survives is taxation papers. Rapid acceleration of world pop"n growth around 1750 to 4. 4 persons per 1000 per year. 1970s science fiction" projections: pop"n x 1 million each 700 yrs. Such rates of growth are not sustainable. At mid 1970s growth, we enter the world of science fiction, with the world population doubling, every 35 years. It would grow x 1,000,000 every 700 years. The population crisis was a paramount global concern of the 1970s just as the environmental crisis/global warming is today. The rise of zpg and pop"n planning as a necessity. But now some relief, with global drops in fertility. World pop"n expected to reach equilibrium of 10-11 billion or less, perhaps as early as 2150. That"s still a big jump from 7 billion, especially where rapid growth continues. Value of over 2. 1 -> natural growth of population, if below, population decline.
