People ask: Why should I care about the ocean? Because the ocean is the cornerstone of earth's life support system, it shapes climate and weather. It holds most of life on earth. 97% of earth's water is there. It's the blue heart of the planet - we should take care of our heart. It's what makes life possible for us. We still have a really good chance to make things better than they are. They won't get better unless we take the action and inspire others to do the same thing. No one is without power. Everybody has the capacity to do something.

We still have 10 percent of the sharks. We still have half of the coral reefs. However, if we wait another 50 years, opportunities might well be gone.

I actually love diving at night; you see a lot of fish then that you don't see in the daytime.

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

Throughout all of human history we have consumed the natural world. All creatures do. Birds do. Fish do. Earthworms do. We consume the natural world as a source of our survival. But no creature has ever consumed at the scale that humans have, and now there are seven billion of us. I think the good news is that a large percentage of those seven billion minds can work to make better decisions.

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.

When you are a child you learn your alphabet, your numbers, but increasingly, we must learn from the earliest stages that the highest priority has to be to maintain the world as a safe place for humankind.
