Most people think visual information is more important than aural information - like, what's this big deal about sound? And why should I bother to listen, rather than look? And here are the facts: there are blind species, in the backs of the caves, the bottoms of the oceans. It's not essential on planet Earth to be able to see, to be a species. But there are no deaf animal species. You have to be able to hear, or you won't get the information you need in order to survive.

We're all born listeners. And as a result of our modern lives, and living in a world that has less meaning than the natural world that we evolved to hear, we learn to think of listening not as taking in all the information with equal value, which is the definition of true listening. In our modern world, we tend to think of listening as focusing our attention on what is important and filtering out everything else.

If you're tired of getting additional information, you can just close your eyes, get some sleep. But earlids, covering of the ears, never evolved. Not once do we find it, even in the fossil records. Because while we let our eyes relax, our ears are still hearing. And that's why alarm clocks work and wake us up. We still gather information. Every animal is gathering information 24/7. So I like to think of acoustic ecologists as people who are trying to become better listeners, 24/7.

I've never really understood how people cannot value the future, or think that the world is going down a fast slippery slope of degradation. No, I don't think so; this is just what it's going to take to wake us up, and allow us to do what our ancestors did. You know, our ancestors brought us here by tooth and claw. A lot of people perished, a lot of pre-humans perished. Life has never been easy. Why should it be easy for us?

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.

We think the problem is out there, when the problem is really in here - who we are and how we experience the world around us. The acoustic ecologist listens, as the primary sense, to the world around us, and I believe that they have a significant contribution to make to all environmental groups who think that they're solving environmental problems, when we're actually all on a spiritual pilgrimage.
