Andrew Marr's Megacities

We are watching a few short clips in class from this excellent Documentary.

For better or worse, tens of millions of others across the globe are making similar migrations, for a variety of reasons, to teeming metropolises, some of which have ballooned to over ten million residents. At that population point, the vaguely science-fiction term urban planners have coined is “megacity”. In BBC One’s recent three-chapter documentary Megacities, BAFTA-winning journalist Andrew Marr examines five immense cities – London, Dhaka, Shanghai, Mexico City, and Tokyo – to reveal their triumphs and tragedies, and discover what makes these unwieldy leviathans tick.
