I really meant it when I said there are only two eras for humanity. For the first 100,000 years of humans before us, our population was more or less stable. It wasn't until agriculture 12000 years ago that things changed.
CrashCourse World History on Agriculture (it's the first episode)
Kurzgesagt on the Human Era which he defines as starting with agriculture.
I'd make an argument that the industrial revolution and its effects on farming were the start of a new era. Improvements to farming, transportation, and storage, and then later fertilizer, It caused a massive increase in the population and an even more radical shift in the percent of population devoted to raising food.
Agriculture led to the population going up maybe 10-20 fold over 6000 years, while the industrial revolution led to population going up over 8-fold in ~250 years. That's a major inflection on the graph.
