Water, Water, Everywhere?

This is my first post using my Google G1 phone and I'm doing it while at swimming lessons for my son and daughter. Anyway, looking at all this water got me thinking about how finite of a resorce water is and how it poses an investment opportunity. I'm going to do some further research on companies in this sector and may establish a small position going forward. Have a good one (HAGO) and we will see where this idea takes us.
