Only two percent of the ocean is fully protected right now.

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

The oxygen cycle, the nitrogen cycle, the carbon cycle, the water cycle - all of these are linked to the existence of life in the sea.

With every drop of water you drink, every breath you take, you're connected to the sea. No matter where on Earth you live.

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.

When I first ventured into the Gulf of Mexico in the 1950s, the sea appeared to be a blue infinity too large, too wild to be harmed by anything that people could do.

I've had the joy of spending thousands of hours under the sea. I wish I could take people along to see what I see, and to know what I know.
