There is not a well-funded campaign among scientists to say, "Look, here's the evidence. You can read it yourself. Here are the facts. We're not making this up."

We couldn't go to the moon on whale oil. We don't have the capacity yet to consider doing such things as harnessing current sunlight. We're burning ancient sunlight in order to get us to where we now are. But it's costly.

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

Ice ages have come and gone. Coral reefs have persisted.

There is an enormous amount to be learned about the sea; like most wildernesses, it has great potential.

If Darwin could get into a submarine and see what I've seen, thousand of feet beneath the ocean, I am just confident that he would be inspired to sit down and start writing all over again.

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.
