Noise pollution is basically defined as the presence of simple information that makes it impossible to hear all the other more delicate - and often more important - information. Noise pollution creates, if you will, dumb environments. Our industrial areas, many of our downtown urban areas, are dumb acoustic environments. Very simple, very loud, often unhealthy.

What visual information does is it creates priorities. You cannot know with certainty what lies behind something else. There are very few transparent materials in the natural world or the built environment. And so we deal with things superficially, and we deal with what's in front of us, not what's behind our head that we can't see, or to the left or the right. Visualists are often linear and timeline-oriented, whereas the natural condition and the natural way of problem-solving throughout evolution is to be multitasking.

When you listen to nature, it may still be difficult to live a life, but it's inspiring.

The Hoh Valley is an incredibly secure area. Any event occurs around us, we will instantly become informed of that event. This can even happen at a distance. When the body recognizes that you have a very large listening area, and you're getting all the information, the body relaxes. You can breathe more gently, the cortisol levels that are created by stress in our bloodstream dissipate, and we actually become healthier. And as a result, if we are actually fortunate enough to live in a place like that, we will live longer.

Whenever you're in a natural system and you're making sound, you are putting yourself at risk. As you go up the evolutionary ladder, from insects to frogs to birds and on up into mammals, the higher intelligence recognizes that when you vocalize, you put yourself at risk. So mammals generally vocalize or make noise much more rarely than, let's say, insects or frogs. And when they do, and put themselves at risk, it has to be worth the risk, and have true meaning, such as signaling during a hunting party, calling in prey, some religious or spiritual ceremony, something like that.

I'm in love with Earth. I truly am. And so listening is not work, to work toward a better future. It's joy. To not be able to work toward a better future would be work. That would be tough.

The earth has continued to change, from rapid climatic changes that have caused the glaciers and the ice sheets to basically bulldoze the landscape and cause species compression in the tropics and cause mass species extinction - you know, all these huge changes. In terms of evolution, every species is doomed to eventual extinction. The natural world is constantly changing. So, to deal with "environmental problems," in quotes, totally misses the issue. That is not the way we want to define our problem if we're going to find our solution.
