Tokyo has a population of over 35 million.

It has been predicted that there will be 19 cities with over 20 million people in the 21st century and that by 2050, over 2/3 of the world's population will live in urban areas.

With the global population growing toward 7 billion and the emergence of megacities, the human species is faced with problems and realities on a scale for which there is no analog in history.

Somebody has to study this. The results are going to have to amount to a far cry more than an 18 minute presentation at the TED conference.
