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

Great attention gets paid to rainforests because of the diversity of life there. Diversity in the oceans is even greater.

Most of life on Earth has a deep past, much deeper than ours. And we have benefited from the distillation of all preceding history, call it evolutionary history if you will.

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.

We humans have this idea that the ocean is so big, so vast, so resilient that it doesn't matter what we do to it. That may have been true 1,000 years ago. But in the last 100, especially the last 50 years, we have destroyed the assets that make our lives possible.

Never before have we known what we know.
