The Search for Silence (3:10) In this April, 2009 KATU-TV (Portland, OR.) interview, acoustic-ecologist Gordon Hempton discusses his search for silence. His book, 'One Square Inch of Silence: One Man’s Search for Natural Silence in a Noisy World', tells the unique story of silence and sound and how they affect and impact our lives in profound ways. The book charts Hempton’s journey across the United States as he travels from his home in Washington State to the nation’s capital in Washington, DC. Hempton argues that “preserving natural silence is as necessary and essential as species preservation, habitat restoration, toxic waste clean-up, and carbon dioxide reduction.” His argument is compelling, and with a green movement sweeping America and the world, Hempton is fighting to include natural silence in the quest for a cleaner, safer planet."
