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.

Healthy areas that are richest in information are those areas in the wild where we can get all the information that's available to us within our human hearing range. The most valuable information throughout human evolution has been faint sounds. We tend to think in our modern world that if it's loud, if it grabs our attention, it's important. We get a lot of that in advertising. But in nature, it's the faintest sound that's important; it has determined, in the past of our ancestors, perhaps, if they will live or die. Faint sounds are the earliest clues of newly arriving information.

You don't really need to engage your visual sense, because the natural wiring of the human psyche is to monitor the environment through sound, not through sight. But we're convinced through modern conditions that we have to look at everything, and that creates stress in our life, because we're trying to solve problems in ways that are much more time consuming, not efficient, and not fun.

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.

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.

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.

If you're listening to a symphony, you're getting all the information, including the audience around you, the delay from the sides of the concert hall, the whole thing. If one of those musicians is sharply out of tune or starts to play a different piece of music than all the others in the orchestra, you immediately notice. When you analyze systems by listening, you can just listen, and you can tell whether the system is healthy or unhealthy. What I've created for you is a perfect model of how we should be listening to our stock market, rather than trying to see it graphically.
