Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.

Humans are the only creatures with the ability to dive deep in the sea, fly high in the sky, send instant messages around the globe, reflect on the past, assess the present and imagine the future.

I have lots of heroes: anyone and everyone who does whatever they can to leave the natural world better than they found it.

Rather than be afraid of evolution and try to stifle inquiry, people should revel in the joys of knowing and find a serenity and a joy in being a part the rest of life on Earth. Not apart from it, but a part of it.

Life in the ocean makes Earth hospitable. We are sailing along in the universe and we have a blue engine that is making everything alright.

We understand that we must make peace with nature - that our lives depend on it.

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