Our oceans are alive with sound, but human activity—such as shipping, drilling, and motorized boating—has created noise pollution that drowns out the natural voices of marine life. Whales, dolphins, and fish rely on sound to communicate, navigate, and survive. If they cannot thrive, the entire marine ecosystem begins to break down—food chains are disrupted, species decline, and the balance that keeps our oceans healthy is lost. Since oceans regulate climate, produce oxygen, and support life on Earth, what harms them ultimately harms us too.
