The distortions in agricultural production are startling. Corn prices are up about 50 percent from last year, while soybean prices are projected to rise up to 30 percent in the coming year, as farmers have replaced soy with corn in their fields. The increasing cost of animal feed is raising the prices of dairy and poultry products.
The news from the rest of the world is little better. Ethanol production in the United States and other countries, combined with bad weather and rising demand for animal feed in China, has helped push global grain prices to their highest levels in at least a decade. Earlier this year, rising prices of corn imports from the United States triggered mass protests in Mexico. The chief of the United Nations Food and Agriculture Organization has warned that rising food prices around the world have threatened social unrest in developing countries.
