Where does your water come from?

       Here's a nifty link: http://www.nature.org/all-hands-on-earth/where-does-your-water-come-from-3.xml

            There are many more links on this subject.

            In the end, all of our water comes from the sky. Even those who have aquifers and wells know that water ultimately comes from the sky. I had an Aunt who even less than a century ago said water came from the tap.

            Now we don't manufacture it, but we do spend a lot of time and money collecting it, storing it, and purifying it.
