We want to think of ourselves as truly special creatures that are unique in the universe and, well, we are. And we have that capacity to wonder, to question, and to see ourselves in the context of all of life that has preceded the present time, and all that will go off far into the future, one way or another.

The end of commercial fishing is predicted long before the middle of the 21st century.

We have the capacity to alter the nature of nature. No, we don't have just the capacity - we are altering the nature of nature, the natural systems that cause the planet to function in our favor.

Look at a child and realize that their future is in your hands. It's not just those who will be here fifty years from now. The decisions we make in the next ten years will shape the next 10,000 years.

My first breath was just...it just seemed impossible that you could actually breathe underwater. I knew in my mind it was possible, but actually experiencing it was such a gulp of joy and I feel it every time I go under the ocean. I love doing it, to be able to feel weightless, to spin on one finger, to do somersaults, to be like a graceful ballerina - even with a huge tank on your back you can do the most extraordinary things.

Fortunately, we know more about the problems that we have than in all preceding history. We know now the consequences of the things that we put into the air, into the water - of the way we treat life on Earth.

With every drop of water you drink, every breath you take, you're connected to the sea. No matter where on Earth you live.
