A friend tipped me off that today (March 22) is World Water Day.
Check out this Nat Geo photo album (one is above) dedicated to water preservation and awareness.
Also, this Saturday (March 27) at 8:30 p.m., support "Earth Hour" by turning your lights off and not using other energy (unless wind power or some other kind of alternative energy). People are designing lanterns out of different stuff to promote.
Here's a site dedicated to Earth Hour.
