The ocean seemed like a sea of Eden. But now we are facing paradise lost.

Just as we have the power to harm the ocean, we have the power to put in place policies and modify our own behavior in ways that would be an insurance policy for the future of the sea, for the creatures there, and for us, protecting special critical areas in the ocean.

Throughout all of human history we've enjoyed certain benign circumstances: an envelope of atmosphere, an envelope of temperature. A kind of resilience that if you cut down trees, then they'll grow back. You take fish, they recover. You put stuff into the atmosphere that you know is not good for us, but we can still breathe. We haven't awakened, generally, to the sense of urgency that does exist.

Eating wildlife is probably not the smartest thing that we can do in terms of maintaining the integrity of natural systems.

The most important thing for people to know about the governance of the Arctic is that we have a chance now to act to maintain the integrity of the system or to lose it. To lose it means that we will dismember the vital systems that make the Arctic work. It's not just a cost to the people who live there. It's a cost to all people everywhere.

When I write a scientific treatise, I might reach 100 people. When the 'National Geographic' covers a project, it communicates about plants and fish and underwater technology to more than 10 million people.

The Earth is a tiny blue speck in a universe of unfriendly options.
