If the sea is sick, we'll feel it. If it dies, we die. Our future and the state of the oceans are one.

Ironically the very energy, the very basis of how we know what we know, has been reliant on having an energy source [necessary] to build rockets to go to the moon and Mars, to support airplanes that fly, and satellites to give us our communication.

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.
