Lifestraw Named World-Changing Idea : TreeHugger

Lifestraw Named World-Changing Idea : TreeHugger: "Lifestraw, the portable drinking filtration system, nabbed the top honor in the fifth Saatchi & Saatchi Award for World Changing Ideas last Thursday. Worn around the neck and used like a regular straw, Lifestraw claims to filter 99.9999 percent of bacteria and 98.7 percent of viruses using a halogen-based resin."

--A beautifully simple idea with potentially massive positive impact.
