Genetically modern humans appeared on Earth about 200,000 years ago and biologically and behaviorally modern humans appeared about 70,000 years ago. The number of people and their effects upon the planet were negligible, or as Douglas Adams says, “as near nothing as makes no odds,” for most of the history of the planet. When did the planets population reach 1 billion people? Assuming that the population has grown exponentially since that time, what was the time interval required to increase by 1 billion people – for up to 7 billion people, the approximate global population in 2012?

From page 1-3 the planet reached 1 Billion people in approximately 1800.
