"Resorting to biofuels is likely to exacerbate world hunger," they said. "Several studies by economists at the World Bank and elsewhere suggest that caloric consumption among the world's poor declines by about half of one percent whenever the average prices of all major food staples increase by one percent."
To which I say, it's a bad thing, but the price of corn in the world market shouldn't matter. We over-produce it already. It's not the great crop people think it is, and it shouldn't be eaten as much as it is. It's got a much lower nutritional value than wheat. It's just easy to grow. It's the kind of food that will keep starving people alive, but starving. Besides which, as the demand for corn goes up, farmers will just plant more corn. I'm not sure that the demand on corn for ethanol will actually cause a shortage. We'll just have to see about that.
In the short term, we can also just subsidize farmers to overproduce more corn than we already do, so that shouldn't be too much to ask. If we want to end world hunger, the answer isn't simply to produce more cheap, bad food.
The truth is that we need to approach world food supplies in a completely different manner. Controlling the number of people on this planet is easier than trying to make all our resources go further. I guess most people don't want to hear or say that we shouldn't all just have as many kids as we want, but that's the plain truth. There's an absolute limit to what this planet can produce, and we certainly don't need to reach or exceed that limit.
