How disruption in a single port, factory or freight centre can cause global chaos. Ed Butler speaks with Stavros Karamperidis, an expert in maritime economics at the University of Plymouth, and Kent Jones, professor of economics at Babson College in the US. Meanwhile, chief economist at Enodo Economics, Diana Choyleva, explains how China's energy crisis will impact exports and the price we pay for goods, and Professor Marc Busch from Georgetown University explains why he thinks governments should leave big businesses to solve supply issues themselves.
