vestal virgin, you really, REALLY need to do some research before spouting nonsense all over the internet.
The same goes for all those who make it look like there's no drinkable water to be found in nature.
I may not have read thirty scientific studies on the matter, but I went on hiking trips and miraculously survived drinking from all those mountain springs that wild animals could theoretically poo in. Didn't even get diarrhea.
That one doesn't drink water that has dead animals in it should be obvious. That doesn't negate the fact that drinkable water can be found in nature, and would be found in nature in much larger quantities without human intervention.
... I have to amend my statement.
Clean water should be free.
Considering that in many places, the tap water is poisonous (and I don't mean bacteria that can be killed by boiling it poisonous, I mean chemical waste poisonous), THAT being for free wouldn't help much.
