Illustrate the Economic Growth
Up until 1800 growth rates of human populations were glacial. Population growth between 5000 B.C. and 1800 averaged less than one-tenth of a percent per year. (However the cumulative magnitude of population growth was impressive, carrying the number of human beings alive on the planet from perhaps 5 million in 5000 B.C. to 900 million in 1800; 7000 years is a long time.)
