You still didn't answer my question. In parts of the world with not much water, etc, people should move to better areas. It's common sense. Lol. Have fun living in your Limited World! Why you enjoy limiting yourself is beyond me, though. When great growth is always possible.
There's a limit on fresh air? Only because corporations pollute the air. If that was stopped what limit would there be? And there doesn't have to be a limit on clean water either. There are several solutions for that.
