A musician named R. Murray Schafer developed the concept of acoustic ecology. He proposed that we should attempt to hear the natural acoustics around us as a composition of music. It is a major concern that our acoustic ecology is deteriorating. Human created sounds are drowning out the sounds of nature and are affecting wildlife both on land and in the ocean. Whales are being displaced by the sounds of oil drilling, ship traffic is affecting fish, and off-road vehicles are changing the natural habits of many wildlife animals.
