The number of chronically hungry people in the world is over 800 million, yet developed countries are facing health challenges from rising rates of obesity. The growing problems of food security and water scarcity seem an issue of distribution rather than availability. But other factors also influence the status of food and water security worldwide. So where does the problem with food and water security lie? Do developed countries – or any other entities or individuals – have any moral obligations to ensure a global network of water and food security? What practical, policy-oriented action can fulfill any moral obligations that might exist? John and Ken grab a bite with Tim Benton, Professor of Population Ecology at the University of Leeds and UK Champion for Global Food Security.
