I became aware of Bernie Krause's TED talk when a birding listserve member posted the link to that list. Bernie Krause's talk is about 15 minutes long and I can't do it justice with words in this blog entry. All I can say is listen for yourself. Depending on the speed of your connection/computer - do give it time to load.
