The National Academy of Sciences and the Global Health Education Foundation have joined with science, engineering, and medical academies from around the world to take action on the global drinking water crisis by launching the "Safe Drinking Water is Essential" website. Although developed with policy-makers in mind, the fascinating graphics and wealth of information, particularly about international drinking water issues, make it a wonderful tool for educators. Visit www.drinking-water.org and enjoy learning about safe drinking water! Once you've finished visiting, let us know what you think about what you've learned.
