Fill the Cup is a campaign of the United Nations World Food Programme (WFP), the world's largest humanitarian aid agency. In 2009, WFP plans to feed over 100 million people in 77 of the world's poorest countries. "Fill the Cup" aims to use the symbol of the Red Cup to raise awareness of global hunger, specifically involving hungry school children. About 59 million primary school age children attend school hungry across the developing world, with 23 million of them in 45 African countries.
