 Beth, great article.  QUESTION:  What's the most precious commodity on Earth today.  Take a look. 
  • GOLD-- $ 1614.00 per ounce
  • SILVER-- $28.00 per ounce
  • PLATINUM--$ 1472.00 per ounce
  • PALLADIUM--$ 606.00 per ounce
  • OIL-- $96.21 per barrel
  •  DIAMOND—Variable
  • RADIOACTIVE MATERIAL—Variable
  • RARE EARTH MATERIALS-- Variable

   In my opinion it's the substance you mentioned in your post--  WATER.  I read another fascinating article recently that basically indicates that in several countries our water table is quickly being reduced due to irrigation needed by farms.  Our desert South West is included as a problematic area.  I think the work done by the Gates' foundation is extremely important.  I am somewhat surprised at the amount of money they allocated for the work but in today's economy nothing is reall cheap.  Really appreciate you bringing this to light.

bobjengr, you are correct that water is probably the most precious commodity.  What's interesting is that its monetary value is so disconnected from its worth.  I'm not talking about third-world needs, but rather places such as the Great Lakes basin where there are water emergencies simply because of where people have chosen to expand to.
