There is a terribly terrestrial mindset about what we need to do to take care of the planet - as if the ocean somehow doesn't matter or is so big, so vast that it can take care of itself, or that there is nothing that we could possibly do that we could harm the ocean.

With every drop of water you drink, every breath you take, you're connected to the sea. No matter where on Earth you live. Most of the oxygen in the atmosphere is generated by the sea.

When some people look at a shrimp they think, "Hmm. Delicious." When I look at a shrimp I think, "You're a miracle, absolutely incredible. Your ancestors have gone back hundreds of millions of years." And to develop a thing as simple as a shrimp cocktail, you have to calculate the hundreds of millions of years that have preceded that moment where you're sitting there with your sauce and fork poised.

The very energy sources that have gotten us to where we are now are also, if we continue doing what we're doing, a shortcut to the end of all that we hold near and dear.

Evolution is not something to be feared. It's to be celebrated, embraced, and understood.

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.

Most of life on Earth has a deep past, much deeper than ours. And we have benefited from the distillation of all preceding history, call it evolutionary history if you will.

When you think about the real cost of so-called cheap energy that has driven our prosperity to unprecedented levels, for some of us, to our horror, we've realized that this has the potential for burning brightly and then snuffing out.

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 diversity of life on Earth, generally, is astonishing. But despite those large numbers, it's also important to recognize that every species, one way or another, is vulnerable to extinction. And in our time on Earth our impact on the diversity of life has been profound.
