While browsing youtube I came across this very thought provoking documentary on depleting water resources of our cities. Even though the documentary talks about Karachi in specific, the problem of potable water and conservation is equally valid for any other city and town of Pakistan. According to current estimate, Pakistan is world’s 6th most populous country taking over Russia for that spot in 2006. With all this increasing population, lack of development of potable water resources, WATER is set to become the most precious commodity in coming years. It will truly become what in literature, people have been calling ‘aab-e-hayaat’.
