There are a lot of smart creatures out there. Dolphins, elephants, and whales are smart. And there are some really smart birds. I know some really intelligent fish. But they cannot know what humans know and are incapable of inflicting as much damage.

People still do not understand that a live fish is more valuable than a dead one, and that destructive fishing techniques are taking a wrecking ball to biodiversity.

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.

I hope for your help to explore and protect the wild ocean in ways that will restore the health and, in so doing, secure hope for humankind. Health to the ocean means health for us.

Many of us ask what can I, as one person, do, but history shows us that everything good and bad starts because somebody does something or does not do something.

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

With respect to the ocean being the heart of our blue planet: We are often asked, 'How much protection is enough?' We can only answer with another question: How much of your heart is worth protecting?
