There are a lot more statistics at Chris' diary.
Number of people that starve each day: 20,000 (from The Hunger Project)
1.2 billion suffer from obesity (GlobalIssues.org)
Number of people suffering from malnutrition to the point where their health, productivity and life expectancy are impaired: 852 million (UN Food and Agriculture Organization)
In the US, 40 to 50 percent of all food ready for harvest never gets eaten. (GlobalIssues.org)
Estimated cost to feed all the world's hungry and give them basic health care: $13 billion above current expenditure. (UN Development Program 1998)
Total estimated cost of Iraq war: about $700 billion (Institute for Policy Studies)
You'll note that I have added an Iraq War Cost counter to the sidebar, special thanks to Limelite for the inspiration.
