> eventually, population growth will overwhelm the Earth’s ability to provide calories. Really? When? And how? Because I don't see how a planet that can support at least a factor of 10 times our population size currently is going to realistically start running out of calories, short of moronic political decisions, some of which are perpetuated by statements like that. Where are these calories going? They're evaporating into the ether, never to be reclaimed? Or is it possible that we're losing out on massive amounts of human capital because, like NIMBY activists that argue against new housing development, we're trying to maintain a status quo out of fear?
