We are not only warming the ocean and the planet as a whole, but we are also acidifying the ocean and changing its chemistry.

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.

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

Meat reared on land matures relatively quickly, and it takes only a few pounds of plants to produce a pound of meat.

Health to the ocean means health for us.

We have been far too aggressive about extracting ocean wildlife, not appreciating that there are limits and even points of no return.

When you are a child you learn your alphabet, your numbers, but increasingly, we must learn from the earliest stages that the highest priority has to be to maintain the world as a safe place for humankind.
