Global food prices on the rise

New data out by the United Nations shows that world food prices rose by 32 percent in the second half of 2010. Food prices for staples haven’t been this high in two years. The last time they reached these levels, food shortages sparked riots in poor nations. Is another food crisis on the horizon for struggling nations? And what does this mean for Americans?

Louise Story, Wall Street and Finance Reporter for The New York Times, says it might not be as bad this year because harvests were fruitful in Africa last year. But prices are likely to remain high for much of 2011.
