When Bernie Krause lowers his microphones into a healthy coral reef, the richness of the sounds is overwhelming. The crystal-clear water pulses with the acoustic range of noises produced by crustaceans and fish, even sea anemones. A kilometer away, where the destruction is visible, one can only hear the sound of the waves and a few crabs making the desolate noises of a dying environment. His passion for nature has turned musician Bernie Krause, who once invented electronic music and collaborated with pop icons like The Byrds, The Doors, Bob Dylan, and George Harrison, into a researcher and pioneer of biophony. For forty years, he has traveled the world to document the richness of species and the unique soundscapes of pristine habitats, as well as their ongoing destruction.
