June 2007 issue of IEEE Spectrum carried a comprehensive report on growth of Megacities. It talked about the pollution levels being highest in Karachi (Pakistan) followed by shamefully New Delhi (India), world urban population to constitute 60% of world population by 2030. London – New York has the highest international Internet Connection at around 387Gb/s.

The report also talks about Sao Paulo’s complex bus system, building a green city in China, Unseen City below New York in the Subways, Earthquake warnings in Japan & Tata Power in Mumbai.
