The most important part is to take on the challenge of protecting the ocean as if your life depends on it - because it does.

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.

Far and away, the greatest threat to the ocean, and thus to ourselves, is ignorance. But we can do something about that.

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.

Why does evolution matter? There is so much about the evolution of life, the development of life on Earth that should rivet the attention of everyone to understand where we've come from and where we might be going. We need to understand the world around us if we are to succeed as a species on the planet.

In the past few decades, Earth's natural systems have endured more pressure than in all preceding human history.

Fish from all over the world, from deep in the sea, wind up in countries from Germany to Japan. That is just crazy.
