I don't get this. Our planet can surely handle 3 billion if it is currently at 7 billion - we wouldn't be fucked at 3 billion.
Doing a bit of number crunching:
Habitable land on earth for humans:
15.6 billion acres
China acres:
2.3 billion
China population:
1.3 billion
Doing the math:
- china population / china acres = world population / world acres
- 1.3 / 2.3 = x / 15.6
- x=8.8174
So, the world will be as populated as china when the world hits 8.8 billion people.
We are currently at 6.7 billion. Only 2.1 billion more people to go.
I think we would be in trouble when we hit the 25 billion level. Technology will change, houses will get smaller, social conditions will adapt. But I don't think we will stop until we hit 25 billion. People, populations, and politicians just don't have the balls to slaughter masses of humans for the good of the species.
On the lower end, I think we would be in trouble at the 50,000 persons level. If we ever got to 10,000 or less humans we would really have to take care at that point.
