美國暢銷書作家Alex Prud’homme的傑出著作《The Ripple Effect》採以調查報告與冒險故事參半手法完成，探討了21世紀地球的最重要資源問題──水。這本書探討的問題跟《Silent Spring》一樣具有迫切性，跟《世界是平的》一樣著眼於當前。本書的電影改編版權已被將艾爾高爾的《不願面對的真相》改編成同名紀錄片上映的電影製作公司取得。

The bestselling coauthor of MY LIFE IS FRANCE with Julia Child delivers a massively important work of investigative journalism in a narrative voice as compelling and eloquent as those of Tracy Kidder and Eric Schlosser. Is water a right like air, or a commodity like oil? In this crucial and informative book Alex Prud’homme cuts to the heart of that fundamental question. Impeccably researched and vividly written, CLEAN, CLEAR, AND COLD addresses timely questions about our most essential and vulnerable resource. What’s in our water? Are we running out of it? How secure is the world’s water supply from natural disasters and terrorist attacks? Will the wars of the 21st century be fought over water? Prud’homme introduces readers to an array of colorful, obsessive, brilliant, and sometimes shadowy characters through which these issues come alive. Like Daniel Yergin’s seminal classic THE PRIZE, Prud’homme’s CLEAN, CLEAR, AND COLD is a masterwork of investigation and a dramatic narrative, spanning the globe. CLEAN, CLEAR, AND COLD will inform, provoke and change our understanding of the importance of water forever. Alex Prud’homme’s books include THE CELL GAME and FOREWARNED.
