The bigger the world population and the higher our standard of living, the more mobile we become. But existing infrastructure is not designed to cope with increased mobility. Roads and rail are already hopelessly congested. In a new episode of the series Lesch’s Cosmos, Harald Lesch explains how we will travel in future, what our cars have to do with the biggest volcanic eruption in history, and he asks why we need to take a more critical look at some forms of transport.
