Brazilian president denies biofuels to blame for world food crisis

Brazil's president blamed rising oil prices for causing the current global food crisis, saying that biofuels had nothing to do with the problem, as some have suggested. President Luiz Inacio Lula da Silva said escalating oil prices were pushing up freight costs, which in turn affected world food prices. "Ethanol production has not contributed in any way to the food price crises," Silva said at a news conference Saturday in Accra, where he was attending a three-day UN Conference on Trade and Development. "It is the oil prices that have brought about high freight charges on the transportation of food," he said.
