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.

Great attention gets paid to rainforests because of the diversity of life there. Diversity in the oceans is even greater.

We've got to somehow stabilize our connection to nature so that in 50 years from now, 500 years, 5,000 years from now there will still be a wild system and respect for what it takes to sustain us.

Our past, our present, and whatever remains of our future, absolutely depend on what we do now.

Scientists never stop asking. They're little kids who never grew up.

Everyone has power. But it doesn't help if you don't use it.

It has taken these many hundreds of millions of years to fine-tune the Earth to a point where it is suitable for the likes of us.
