Megacities

Sixty years ago there were only two megacities - cities with over 10 million inhabitants - on the planet: New York and Tokyo. Now there are 23 and by 2025 the UN predicts there will be 37, all but eight in the developing world. The Guardian has a special interactive report investigating this trend - take a look at it here. Then have a look at the data.
The pictured city Shanghai is home to at least 20 million people, half of whom are immigrants from other parts of China.

Are we heading for impending disaster? Take a look at some of the following videos and resources to help you ponder these questions?
