That really won't be a problem, the food supply I mean. We can build giant skyscraper communities that put tons of people & farms inside columns that take up tons of vertical space but not much horizontal space. Absolutely the technology is already there today that we could have a much higher population and not starve.

So I don't see food as something that keeps us in check. We're more likely to hurt ourselves with overpopulation in ways we don't realize. We'll pave over the magic pond that sustains all life and overnight everything will die. OK, that's far fetched, but we will screw something up that we never would have thought of. Something that never would have occurred at lower population levels. I don't see it as an "if" in my mind, but rather a "when". Of course I put the "when" to be beyond my lifetime. So you know what? It's someone else's problem, let them figure it out.
