" 'The day will come when man will have to fight noise as inexorably as cholera and the plague.' So said the Nobel Prize-winning bacteriologist Robert Koch in 1905. A century later, that day has drawn much nearer. Today silence has become an endangered species. Our cities, our suburbs, our farm communities, even our most expansive and remote national parks are not free from human noise intrusions. Nor is there relief even at the North Pole; continent-hopping jets see to that. Moreover, fighting noise is not the same as preserving silence. Our typical anti-noise strategies — earplugs, noise cancellation headphones, even noise abatement laws — offer no real solution because they do nothing to help us reconnect and listen to the land. And the land is speaking.

"We've reached a time in human history when our global environmental crisis requires that we make permanent life-style changes. More than ever before, we need to fall back in love with the land. Silence is our meeting place.

"It is our birthright to listen, quietly and undisturbed, to the natural environment and take whatever meanings we may. Long before the noises of mankind, there were only the sounds of the natural world. Our ears evolved perfectly tuned to hear these sounds — sounds that far exceed the range of human speech or even our most ambitious musical performances: a passing breeze that indicates a weather change, the first birdsongs of spring heralding a regreening of the land and a return to growth and prosperity, an approaching storm promising relief from a drought, and the shifting tide reminding us of the celestial ballet. All of these experiences connect us back to the land and to our evolutionary past.

"One Square Inch of Silence is more than a book; it is a place in the Hoh Rain Forest, part of Olympic National Park — arguably the quietest place in the United States. But it, too, is endangered, protected only by a policy that is neither practiced by the National Park Service itself nor supported by adequate laws. My hope is that this book will trigger a quiet awakening in all those willing to become true listeners.

"Preserving natural silence is as necessary and essential as species preservation, habitat restoration, toxic waste cleanup, and carbon dioxide reduction, to name but a few of the immediate challenges that confront us in this still young century. The good news is that rescuing silence can come much more easily than tackling these other problems. A single law would signal a huge and immediate improvement. That law would prohibit all aircraft from flying over our most pristine national parks.

"Silence is not the absence of something but the presence of everything. It lives here, profoundly, at One Square Inch in the Hoh Rain Forest. It is the presence of time, undisturbed. It can be felt within the chest. Silence nurtures our nature, our human nature, and lets us know who we are. Left with a more receptive mind and a more attuned ear, we become better listeners not only to nature but to each other. Silence can be carried like embers from a fire. Silence can be found, and silence can find you. Silence can be lost and also recovered. But silence cannot be imagined, although most people think so. To experience the soul-swelling wonder of silence, you must hear it."
