How food shapes our cities

Every day, in a city the size of London, 30 million meals are served. But where does all the food come from? Architect Carolyn Steel discusses the daily miracle of feeding a city, and shows how ancient food routes shaped the modern world. Understanding the flow of food will help us reconnect with what we eat. (Recorded at TEDGlobal, July 2009, Oxford, UK. Duration: 15:41)
