Document Summary
Population growth has not been as rapid as it is today. 2000 years ago the population totaled 300 million and roughly 300,000 people were being added per year: today, there are 80 million people added a year. It took all of human history to reach 1 billion people, less than 200 years later the planets total is now over 7 billion. 2 major revolutions in human history that caused significant population growth: 1. Occurred 12,000 years ago when humans in large number began to give up hunting and gatherings to settle down in one location as farmers. Neolithic revolution: the domestication of agriculture and livestock. The transition from hunting/gathering to farming occurred gradually over thousands of years. The first locations were probably in the fertile crescent of the middle. East, what is now primarily iraq and syria. From 10,000 bce until 1750 or so, the world"s population grew slowly but steadily.
