Mumbai’s Shadow City- Dharavi
This shadow/squatter city within the city of Mumbai,is  home to 100,000 plus people. Beleive it or not, Dharavi churns out some 500 million dollars worth of goods. The mostly unregistered and unregulated industries range from tanneries to plastic re-cyclers, garment factories to potters brick kilns. Everything is there.

Listen to these TED Talks from Stewart Brand and Robert Neuwirth, regarding shadow cities. They are examined in a new light as centers of ingenuity and innovation. I never cease to be amazed by entrepreneurs. The talks are 3 minutes and 14 minutes and full of Entrepreneur-Tales From the Front.
