If you are interested in looking at water from a perspective a little closer to home, you can view these TED talks that discuss water scarcity and contamination. Prepare to be awed when Michael Pritchard cleans and drinks non-potable water in the TED Talk: How to make filthy water drinkable. Then watch young teenager, Ludwick Marishane, 2011 Global Student Entrepreneur of the Year, as he presents to a TED audience how to take a bath without water. Just think of the global implications of this invention. Less time walking and searching for water, and more time to learn, study, and go to school for girls. The TED Talk: Better toilets, better life: addresses sanitation in India and inspires you to ponder what your world would be like without good water quality. National Geographic also has a complete website on WATER. Visit this site, and learn all you can about this precious compound necessary for life on Earth.
