The global denial continues. Riots, instability spread as food prices skyrocket (CNN) -- Riots from Haiti to Bangladesh to Egypt over the soaring costs of basic foods have brought the issue to a boiling point and catapulted it to the forefront of the world's attention, the head of an agency focused on global development said Monday. 1 of 2 "This is the world's big story," said Jeffrey Sachs, director of Columbia University's Earth Institute. "The finance ministers were in shock, almost in panic this weekend," he said on CNN's "American Morning," in a reference to top economic officials who gathered in Washington. "There are riots all over the world in the poor countries ... and, of course, our own poor are feeling it in the United States." <snip>... "The contrived food vs. fuel debate has reared its ugly head once again," the Renewable Fuels Association says on its Web site, adding that "numerous statistical analyses have demonstrated that the price of oil -- not corn prices or ethanol production -- has the greatest impact on consumer food prices because it is integral to virtually every phase of food production, from processing to packaging to transportation." Analysts agree the cost of fuel is among the reasons for the skyrocketing prices. Another major reason is rising demand, particularly in places in the midst of a population boom, such as China and India. Also, said Sachs, "climate shocks" are damaging food supply in parts of the world. "You add it all together: Demand is soaring, supply has been cut back, food has been diverted into the gas tank. It's added up to a price explosion." Cut back? Try "running out."
