By putting pressure on global supplies of edible crops, the surge in ethanol production will translate into higher prices for both processed and staple foods around the world. Biofuels have tied oil and food prices together in ways that could profoundly upset the relationships between food producers, consumers, and nations in the years ahead, with potentially devastating implications for both global poverty and food security.Ethicurean links to Will Saletan at Slate and the Washington Post, who dissents ... er, half-dissents.
True, biotechnology can go wrong. But it can also go wonderfully right. Scientists are learning to split corn so it can make ethanol and still feed animals. We're studying the use of microbes to extract fuel from straw and wood waste. We're trying to grow biofuel in algae. We're even learning to make fuel from animal fat and excrement.
Yes, ethanol subsidies are a scam. Yes, we should drop our trade barriers and let Brazilian sugar cane wipe out American corn. Yes, we need solar power, conservation, and efficiency. But don't give up on biofuel. It just needs time to grow.
