Some experts look at global warming, increased world temperature, as the critical tipping point that is causing a crash in coral reef health around the world. And there's no question that it is a factor, but it's preceded by the loss of resilience and degradation.

The most important part is to take on the challenge of protecting the ocean as if your life depends on it - because it does.

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.

Fish from all over the world, from deep in the sea, wind up in countries from Germany to Japan. That is just crazy.

We are depleting this immense diversity and abundance of life, and it matters tremendously for the future of the planet.

Never before have we known what we know.

The next 10 years could be the most important in the next 10,000.
