Excuse me, if this is the wrong sub for this but I’m genuinly confused. According to [this graph](https://flic.kr/p/5T5hkE) I found by accident, the world population barely increased at all between 1300 and 1900. And then it suddenly took off like crazy. What caused this sudden fast increment of the world population?

If I had to pick one cause, I will say it was the availability of cheap energy. Cheap coal and oil fuels our society, be it via fertilizers or our machines. This leaves us free to chase other endeavors.
