Yes, we do, Peace. The problem is not in the amount available, but in the distribution of it. It's just another side of what ol' Tom Malthus predicted back in the 18th Century.

We could use the corn stalks (maize) left in the fields for biomass for fuel. We could stop burning fields (as is done right here in Idaho) and use the stubble for biomass. We could do a lot of things.

But that requires changing the way we think: about nature, about the world, about food production, about food distribution, and above all else, about each other.
