Check out the World Bank's focus on the Food Price Crisis at http://www.worldbank.org/html/extdr/foodprices/
Some facts I learned from the site:
-High food prices are a matter of daily struggle for more than 2 billion people.
-High prices threaten to increase malnutrition, already an underlying cause of death in over 3.5 million children a year.
-An estimated 100 million people have fallen into poverty in the last 2 years.
-Prices are expected to stay high through 2015.
-Poor families spend up to 80% of their budget on food.
I found this site through a great article on the Christian Foundation for Children and Aging website.
