Living in a large, crowded city, I’m used to a constant background noise of traffic, voices, car alarms, and street dogs. Apparently, the ocean is becoming a much noisier place as well, as the rapid increase in global trade has led to more, larger, and faster ships on the high seas. Unlike sound waves in the atmosphere, the sound waves produced by these ships can travel long distances in the water. How this affects marine organisms, especially those that use sound for communication, is unknown.

Just one of the many ways human activities could affect the living world.
