Baleen whales such as humpbacks use songs to communicate, search for food, find mates and navigate the seas,but in Japan, their voices are being drowned out by the din of cacophonous human activity. The new study, published Wednesday in the journal PLOS ONE, adds more evidence that human-generated noise pollution interferes with marine life. Our oceans are getting noisier due to increasing human activity, including shipping, military sonar, underwater construction and seismic blasts for oil and gas. Scientists have previously found that these auditory onslaughts can threaten the health and lives of various sea creatures.
