Documentary: Bernie Krause - Sound of Extinction

Sounds of Extinction (1:49) For musician and "soundscape ecologist" Bernie Krause the authentic sound of the wild can be more disturbing than any synthesized film score. 

For 44 years Krause has traveled across the globe recording the sounds of the natural world and has amassed an archive of more the 4,500 hours and over 15,000 individual creatures. But perhaps the most remarkable part of Krause's back catalog of nature's orchestra is that that around 50% comes from now silent or extinct habitats.
