........Someone famous once wrote that WARS and PESTULANCE control the human population (when they exceed their holding capacity).

Here is a chart of world population over the past few thousand years. Prior to date at the start of this chart it is pretty much flat line.
Agriculture started around 10,000 years ago.
If you look at the chart, from 10,000 BCE to 8,000 BCE the population growth was essentially zero - very little. Around 8,000 BCE (I think) agriculture started and you can see a slight flow occurring. After that I think the chart is self explanatory.
From what I have read that is because that is the level of population the world could sustain with only hunter/gatherers. Once agriculture started, there is evidence that agriculture allow our brains to grow (more calories, it is needs more as it got bigger) and allow for people to start living longer and reproducing. More of the spawn survived, since they had more food - from there it is a normal exponential growth curve. With the past couple hundred years on the liftoff portion.
