What Will Happen If The World Runs Out Of Water

we tend to live life in a bliss of ignorance, ignoring the little things that mean a lot to us, such as water.
However, what we will be able to do once the world runs out of water? It's already been established that we cannot create water, so what will happen?

1:- There will possibly be a world wide famine, many people will start to fall sick as they cannot revive their daily uptake of water & many people will end up dying.

2:- There's already war occurring over oil, oil and water have one thing in common, they both have the same chances of being scarce. So imagine, many years down the line, when water does finally run out, there will be war between different countries for a clear tasteless but valuable liquid.

to conclude, call this rash thinking or me being 'extra', however these things should be thought about now so we can prepare not just ourselves, but the future for what it has to give!
