The World's Fresh Water - Have Supplies Peaked?

Research from MacArthur "Genius" Fellow Peter Gleick and his colleagues finds that more and more regions of the world, including the U.S., may be reaching the point of "peak water." Protecting this most vital of resources without harming public health or the economy is no easy task. We explored the issue with Gleick, one of the world's foremost experts on the subject, during his recent visit to the Wilson Center. Peter Gleick is Co-founder and President of the Pacific Institute for Studies in Development, Environment, and Security.
