Hidden Beneath the Waves

Fellow Mainer Russell Wray writes:

Check out this trailer from the film Sonic Sea. Because it is taking place below the ocean surface, most people are unaware of this huge problem...Out of sight, out of mind. But Navy sonar, shipping, oil and gas exploration and extraction, and other human activities are responsible for causing a huge problem for many forms of marine life...a problem that is a matter of survival...not only for those living in the sea, but also for those of us on land, as we all depend upon healthy, living oceans...
