In a fascinating three-part series, Andrew Marr reveals how these heaving mega-metropolises feed, protect and move their citizens. From the
gleaming skyscrapers of Shanghai to Dhaka’s toughest slum, from London, the grand old man of metropolises, to the colourful streets of Mexico City and hi tech Tokyo.
Andrew discovers how the megacity defines every aspect of its inhabitants daily lives and asks if the future of megacity is the future of the human planet.
