Today it is water, tomorrow it will be air that we breathe, then sunlight and then what not !! Per capita availability of water has gone down Not because of water shortage but because of uncontrolled population and overcrowding of cities. If we build new cities spaced far apart, ground water will never be a problem there. This is beginning to happen along Yamuna and Ganga Expressways where several new cities have been planned. These cities will never ever have any problem of ground water. Places like Delhi where overcrowding is increasing, will see water shortages due to MISMANAGEMENT, not shortage. There is NO problem of availability of water in Delhi, it is available in any quantity one wants, but through tankers run by political mafias, not through Jal Board, whose job it is to provide clean water at reasonable price. Bottled water is criminal loot of the common people.
