Brilliant post on Roving Bandit highlighting the ridiculousness of some of the "we're all about to run out of food!!!" hysteria. Go. Look.
I work with food security facts and figures every day. Neo-malthusian paranoia about the world running out of food makes me sad. Not only because it requires an entirely a-historical analysis of the situation, but because it distracts from the actual, real-life hunger and food insecurity that are actual, real-life problems in the here-and-now.
