Why is corn-derived ethanol criticized for contributing to world hunger?
Critics of corn-derived ethanol maintain that the growing demand for corn-derived ethanol has played a role in driving up food prices. Consequently, the United States, the worlds largest food donor, has drastically reduced its levels of food purchases for developing nations within the last few years. The higher food prices not only have reduced American food aid for the worlds poor but also are making it harder for the poorest people to buy food for themselves.
