Patel says "2008 was a record year in terms of harvest. There's more food per person in 2008 than there's ever been in history. The problem is not food, but how we distribute it."
Other causes for the rise in global hunger have been documented. They include:
• Surging oil costs have made it more expensive to harvest, fertilize, store and deliver food.
• The rise in droughts and hurricanes worldwide has wiped out crops and made farming more difficult.
• The world is running out of the raw materials -- water, oil, good farmland -- needed to keep the food system intact.
"A lot of people have begun to understand at various levels that the food system, as it is, can't go on," says Paul Roberts, author of "The End of Food."
