Will we run out of water before fuel?

Water is recyclable, fuel isn't. When you drink water, and you urinate through the toilet, where do you think it ends up? It gets renewed and all of the toxins are rid through several processes (not gonig to explain all of this though) ; so theoretically speaking, us humans drink our own urine? No. >_>

Water is something that can be renewed/restored, here's another example. There's a lake, when it's hot, it evaporates, eventually, it becomes rain, and water falls back down into that lake. It's a never-ending cycle.

the cost of cleaning that water is what is going to make it expensive to buy water. the water in the lake will become acid rain, try drinking that. pollution is the problem we face when it comes to drinking water.
