Sound Pollution
Over the past couple of decades, the amount of noise in our oceans from motor boats, shipping traffic, jet skis, sonar, and oil rigs, has greatly increased. Because of this, noise pollution is becoming a major problem in our oceans.
Whales and dolphins rely on sound to communicate, hunt, and visualize their environment over a large distance. The increases in artificial or man-made sounds are making it hard for the whales and dolphins to hunt and communicate with each other.
Research is done on the increasing noise pollution in our oceans because it is possible the cause of the increase in accidental beaching. Probably the whales become disoriented and end up beaching themselves accidentally.
