I have a lot of respect for Sen, and found this Op-ed up to par. There's not much new information here, but he's synthesized a strong explanation for the food crisis.

A very important perspective, at a very important moment. Oil is not the only resource in short supply. In fact the only thing not in short supply are people. And it's that, uncontrolled population growth, that's the fuse burning on a bomb that will, if not addressed quickly and strictly, will result in the untimely death of millions, possibly a billion, in the decades ahead. l

Excellent op-ed piece. The author takes aim at a major culprit of the food crisis: "Ethanol use does little to prevent global warming and environmental deterioration, and clear-headed policy reforms could be urgently carried out, if American politics would permit it." In the not too distant future, politicians will have to switch from special-interests pandering to making hard decisions about limiting the earh's population as the number of babies being added outstrips our ability to feed them.
