It's been said that everything that is to be seen has already been seen. But as far as our planet's oceans are concerned, nothing could be further from the truth.

Recently a veteran underwater videographer saw a 26-foot-long pyrosome--a colony of tiny sea animals who link together into a free-floating mass. As if that wasn't fascinating enough, this undulating "ocean worm" has a bioluminescent glow. The awestruck diver put it this way: "Even the most articulate person in the world couldn't describe that creature that we filmed."

The ocean covers 71 percent of the Earth's surface, and although it's likely impossible we could ever get a count that's close to accurate, we know that more than a million species call it home. While scientists have calculated the square miles that it covers and the trillions of gallons of water that it holds, the numbers are too big for us to comprehend. Yet despite its almost unfathomable size, humans are damaging its vast ecosystems in far-reaching ways.

More than half the world's oceans are being fished industrially, and the UN's Food and Agriculture Organization says that one-third of commercial fish stocks are being caught at levels that are unsustainable.

The massive weighted nets that are dragged along the seabed for miles in a practice known as "bottom-trawling" pick up anything and anyone in their path. Non-target animals, referred to as "bycatch," can make up as much as 90 percent of what is hauled in. Millions upon millions of animals, including turtles, dolphins, rays, octopuses, sharks and others have been killed in this way.

Countless marine animals also suffer and die when they become entangled in discarded fishing gear, ropes, abandoned traps and other debris.

Coral reefs support huge numbers of marine animals, including thousands of fish and other species. In fact, some scientists believe that there may be millions of undiscovered species of organisms living in and around them. Yet, coral reefs around the world are in serious jeopardy.

Scientists estimate that 95 percent of the ocean remains unexplored. Ninety-five percent! Yet humans seem hell-bent on destroying it and all its inhabitants. In addition to all the fascinating sea life we already know about, what other marvels share our planet and how many will be gone--without us ever knowing they existed--because of our destructive ways? Our personal choices can make a difference. From ditching plastic straws and bags to leaving vulnerable sea animals off our plates, let's all be more mindful of our habits.
