Silent Tsunami: Global Food Crisis

World food prices are soaring. The world's poor are hurting. And the price hikes may pinch in a supermarket near you.

In Cameroon and Burkina Faso and Egypt and Indonesia, they've rallied and rioted over hunger and the high price of food. In Haiti, they've turned out a government.

The U.N. calls it a "silent tsunami," but it's loud out there now. Between global warming, high oil and fertilizer prices, rising demand, and food crops poured into ethanol, we've got a hungry, angry world out there. And don't imagine you're immune.
