And so everyone will die, and the WORLD WILL COME TO AN END huh? It is so fashionable to scare people into a panic over every problem.

No, but wars are fought over things like this, and we should be concerned over the possibility of an exchange between two nuclear nations (India,China) when both believe their survival depends on control over this scarce resource.

"No, but wars are fought over things like this, "

You need to look at a map. India and China are separated by the Himalaya Mountain range, not a river. The water which flows to China would be too expensive to transport to India to make it commercially feasible, and vice versa.

If you are talking about ground water, forget it. There is no way the Indian or Chinese government could control their own citizens wells let alone each others, and they don't share a common aquifer anyway. India is a subcontinent. The Himalayas are evidence of the Indian and Asian continents collision. There is no interaction between their respective aquifers.
