Peter H Gleick

More than 85 million bottles of water are sold every day in the United States. Freshwater expert Peter Gleick explains what's in them -- and why we drink them -- in the book Bottled and Sold: The Story Behind Our Obsession with Bottled Water.

A MacArthur Fellow and co-founder of the Pacific Institute, Peter Gleick runs one of the nation's leading water-conservation assessment centers.

The institute's biennial report, The World's Water, surveys global water trends and issues, including the links between water and terrorism and the growing risk of flood and drought.
