When I last visited Karachi it is so much changed from the one I use to remember only 10 years ago. I did'nt see these changes in the 15 years that I spent there.
Most of the people I met say that there is now much more traffic than these roads can handle. Shops are open late and everyshopowner has to rely on generators.

I think the next big catastrophy to hit karachi would be the electric power unavailability. There has been no planning done for future or was done in the last 15 years for the situation today. Despite all the claims of the politicians no effort is evident from any side.
