The world is going to end. I say in about five years from now.

But it won't be from global warming or any of that nonsense. It'll be the result of a criminal mastermind poisoning the worlds drinking water. Then with the only source of clean drinking water, the criminal mastermind will monopolise clean drinking water and mark it up to an insanely high price. Eventually, this clean drinking water runs dry, and everyone dies from thirst.
The End.
