London summit tackles rising food prices

The world faces a "silent tsunami' of soaring food prices and more must be done to help secure future supply, the U.N. food agency said Tuesday as experts gathered in London for a special summit on the problem. The United Nations World Food Program (WFP) said an extra 100 million people who previously did not require help could now not afford to buy food. It said the soaring prices threatened anti-poverty and health improvement initiatives in the world's poorest nations and left a $755-million hole in the organization's $2.9-billion budget.
