Josette Sheeran, the head of the UN’s World Food Program, talks about why, in a world with enough food for everyone, people still go hungry, still die of starvation, still use food as a weapon of war. Her vision: “Food is one issue that cannot be solved person by person. We have to stand together.” (Recorded at TEDGlobal 2011, July 2011, in Edinburgh, Scotland. Duration: 19:10.)
