Recording the Sounds of Extinction

Musician and naturalist Bernie Krause is one of the world's leading experts in natural sound. Krause has been recording "soundscapes" - the wind in the trees, the chirping of birds, the songs of humpback whales - for over forty years and has amassed the largest archive in the world. In doing so, Krause can chart how wildlife sounds have changed over the course of climate change. Listen for yourself: the silence speaks volumes.
