One Man's Quest To Save America's Vanishing Quiet Spaces (VIDEO)

America is losing its quiet spaces; or more specifically, it's losing the spaces where all you hear are the sounds of nature. In Julia Baird's Newsweek article, she profiles and interviews audio ecologist Gordon Hempton, who, along with John Grossman, wrote One Square Inch of Silence: One Man's Search for Natural Silence in a Noisy World.

Hempton argues that "silence is rapidly disappearing...[and] there are a fewer than a dozen places of silence [in America]." He believes that such silence -- found in natural settings undisturbed by human activity and sound -- is completely underrated, yet it profoundly contributes to our well-being.

Check out this video of Hempton sharing his passion for recording "silent" natural spaces around the world as well as his belief that such spaces need to be preserved:
