Oh Great, Now we're going to burn up the one natural resource we actually need to Survive.
Oil We didnt need to support life, Water seems like a vast ammount, but it isnt endless. If everyone uses water like that, and it becomes a main stream power source. Thats plants taking it, humans taking it, processing that wastes it, powering our vehicles, they use it for so much stuff, if we end up using it, in a couple hundred years (If the world lasts that long) It'll start to vanish just like oil has
