Until 10000 BC the world lived as hunter gatherers. Some view the hunter gatherer lifestyle as more in tune with nature.
[Hunger Math] The land needed for each hunter gather ranges from 40 hectares per person in an ideal ecosystem, to 150-250 hectares per person for a moderately favorable ecosystem. In unfavorable ecosystems, the number can go very high, to over 1,000 hectares per person. Let’s assume an overly-optimistic 100 hectares per person for hunting and gathering. This means 136 million people on earth.
So returning to being hunter gathers would merely cost 7.1 billion lives.
Some use population growth rates and project that unchanged exponential growth would lead in 3500 years to a massive ball of human people expanding out at the speed of light.
