I don't know where you got the idea that I was talking about famine in Syria. I'm not. I'm talking about world-wide famine. If the way we feed the world isn't sustainable, then there's going to be a global problem eventually.

Nor am I talking about enforcing population limits.

Bringing all of humanity out of poverty isn't going to do it either, if they all want to have an American diet.

I didn't get that idea - I posited that idea. No one is talking about the famine in Syria. If people don't care that people are starving now, they won't care when a few billion more from poor countries are either.

That's not how it works - the world has enough food for current population P + x offspring. Whenever food supply starts to dwindle P+x will go down. Less people will survive at the fringes - the poor will die, much like they do now, hence I brought up Syria, which no one on here talks about, because they don't care.

A worldwide famine would be the result of catastrophic failure. Catastrophic failures you're suggesting will impact any population size regardless of its sustainability. Sustainability is about maintaining resources without depleting them - it's inherently different than catastrophic events destroying most of the system. No amount of sustainable farming matters if, say, a meteor impacts the earth, or global warming renders most land un-farmable. There is no sustainability fix here.

It's the only proven way to reduce birthrate without war and disease.
