Loud noises in the world’s oceans, caused by ships, powerful sonar, and oil and gas exploration, are negatively affecting a range of sea critters, including whales, dolphins, sea turtles, and others, according to a report by the International Fund for Animal Welfare. Increased noise levels have not only been scaring animals and shortening the distance over which they can communicate with each other, but some loud noises may directly cause tissue damage while others can spur animals into surfacing too quickly, leading to injuries similar to the bends.
