Here are 2 for you: the first is an eye-opening one about the importance of opening our eyes to World Water Day 2013. The 2nd one tells you some of the science of water (and the importance of potable [= drinkable] water), proving the point that "Water is Amazing" (created for World Water 2012 last year.)
World Water Day this year is March 22nd, 2013.
To learn more about World Water Day, check out the United Nations World Water Day 2013 brochure or their website... or check out Water.org (Co-founded by Matt Damon). 2 great (& humorous) videos can be found on the Matt Damon link! Definitely check those out!!
