This is a living planet. Look around. Mars, Venus, Jupiter. Look beyond our solar system. Where else is there a place that works, that is just right for the likes of us? It has not happened just instantly. It is vulnerable to our actions. But it's the result of four and a half billion years of evolution, of change over time. And it changes every day, all the time. It would be in our interest to try to maintain a certain level of stability that has enabled us to prosper, to not wreck the very systems that give us life.

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

There's plenty of water in the universe without life, but nowhere is there life without water.

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.

I suggest to everyone: Look in the mirror. Ask yourself: Who are you? What are your talents? Use them, and do what you love.

The oceans deserve our respect and care, but you have to know something before you can care about it.

The ocean governs the climate and the weather, it is taking care of the temperature and it is shaping the chemistry of our planet.
