This is the result of mindless and unplanned economic hunger. Industries and town overusing the meagre water resources. And the warming through the industries is changing the climate. Coal is China's main energy source and it requires huge amount of water to extract and wash. With the water shortage, soon China would be having a energy crisis. It should be a wake up call for India so that we do not go about industrialisation in the mindless way as China has done, just to make money. Money making is good, but mindless money making leads to money loss and brings about untold miseries.
