Sounds of a healthy ocean can bring degraded marine ecosystems back to life

A healthy marine ecosystem is an orchestra of sounds - the rhythmic humming of fish calling to each other, crabs scuttling along reefs and sea grass rustling in the currents. But when an ecosystem is dying, not much life is there to make sounds.

Marine animals don't tend to flock to these wastelands. So when an ecosystem is degraded by human interference, storms or heat waves, it has a harder time coming back to life. If marine animals think there's life in these faltering environments, however, they are more likely to check them out and even put down roots.
