The global financial meltdown has pushed the ranks of the world's hungry to a record 1 billion, a grim milestone that poses a threat to peace and security, U.N. food officials said Friday.(..) Josette Sheeran of the World Food Program, another U.N. food agency based in Rome, said hungry people rioted in at least 30 countries last year. Most notably, soaring food prices led to deadly riots in Haiti and the overthrow of the prime minister. "A hungry world is a dangerous world," Sheeran said. "Without food, people have only three options: They riot, they emigrate or they die. None of these are acceptable options."
