Water is among humanity’s greatest needs. Of the world’s supply of water; 97% is in the ocean and 2 % is frozen. This leaves just 1 % of the world’s water left for drinking. When I see a statistic like this, I get the initial reaction that we all get: a bit of shock. But what exactly does that mean, 1 %? How much water is that? How much do we need? It is a shocking statistic, but in itself it doesn’t mean much. I am not doubting that there is a water crisis. Maybe not in America but in other countries for sure. And perhaps someday we Americans will be faced with a water crisis. We already have a strange fascination with bottled water. Ooh, it’s from a rare mountain spring. Oh my God, what flavor!. Fortunately, a lot of people have gotten hip to this whole bottled water scam and discovered a way to make their own filtered water. The result has saved them loads of money, natural resources, and energy. There are a lot of ways to filter or clean water. In my article How to Clean Water, I have listed all that I am aware of. I have also included the benefits and downsides for each.
