Well, it may be economics that saves us too. If wheat prices are going up so much, that's an incentive to plant more wheat. In theory, at least, that ought to bring the supply and demand back into balance and go some way toward moderating the price.
Of course, if there are government subsidies to plant more corn, that's a problem. The political and ethical issues surrounding biofuels are tricky, but I think there's a growing awareness that we need to come up with a fuel solution that doesn't endanger the food supply. (The scientific issues are, from what I understand, less tricky--but nobody seems to care about that.)
This all leads naturally into larger questions about our industrialized food system. Personally, I find that system distasteful in many ways, but nearly impossible to escape. Michael Pollan wrote an interesting book on the topic, which I'm sure many of you have read:
Amazon.com: The Omnivore's Dilemma: A Natural History of Four Meals: Michael Pollan: Books
He's not pushing an agenda--at least, I don't think he is--but reading the book really brings to light the number of ethical questions we gloss over or completely ignore in the interest of convenient and (until now) cheap food.
I'd better quit before I
really start to ramble.
