When you write about something like water, you run the risk of the material being biased with your point of view. I have realized my point of view is about water, just plain old water:  Conservation, reuse, cost of energy generating clean water, availability and contamination of water   I just read an article, which I found confirms what we all know about the US.  We consume more than any other country, and of course that means we probably waste more than any country. 

We Americans are a people that are the most giving and charitable on this planet, yet we waste more than some will ever have.  You cannot give water to other nations and people in need, but you can conserve for our future.  Please check out this link http://www.yesmagazine.org/issues/water-solutions/just-the-facts-water-footprints from YES magazine’s new issue to see how much we consume and think that we could save 30 to 40% of our personal residential use by recycling our greywater to flush our toilets.
