When you look at our planet from space, one thing is abundantly clear: Earth Is Blue. Our planet is an ocean planet, and whether you live near the coast or a thousand miles from it, the ocean is part of your life. From providing the food we eat to determining our weather, the ocean matters to each of us -- and the National Marine Sanctuary System protects this vital resource.
With that in mind, the photos and videos of Earth Is Blue bring these ocean treasures directly to smartphones and computers all over the world, where they can serve as a tangible reminder that no matter where you are, the ocean and Great Lakes are in your hands. We hope these images inspire you to help care for our ocean and to spread the word that Earth isn't green -- it's blue.

Corals like this one in National Marine Sanctuary of American Samoa form the backbone of healthy ocean ecosystems. Coral reefs support more species per unit than any other marine environment, including some 4,000 species of fish! Corals also form the backbone of healthy human communities. They buffer shorelines from wave actions and prevent storm damage, they provide food and recreational opportunities, and even are the source of new medicines. What do corals do for you?
