I've always said, 'Underwater or on top, men and women are compatible.'

I want to get out in the water. I want to see fish, real fish, not fish in a laboratory.

If Darwin could see what we now see, what we now know about the ocean, about the atmosphere, about the nature of life, as we now understand it, about the importance of microbes - I think he would just beam with joy that many of the thoughts and the glimpses of the majesty of life on Earth that he had during his life, now magnified many times over.

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

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

The Earth is a unique system in the universe, the only planet we know of that's hospitable for humankind.

We need to respect the oceans and take care of them as if our lives depended on it. Because they do.
