We need to respect the oceans and take care of them as if our lives depended on it. Because they do.

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.

If Darwin could see what we now see, what we now know about the ocean, about the atmosphere, about the nature of life, as we now understand it, about the importance of microbes - I think he would just beam with joy that many of the thoughts and the glimpses of the majesty of life on Earth that he had during his life, now magnified many times over.

The image of Earth from space transformed our view of ourselves. It is maybe the most important image that exists - because we can see ourselves in context in a way that otherwise would be really hard to explain. It should inspire us to wonder about it, to want to know everything we can about it and do everything we can to take care of it.

If you think the ocean isn't important, imagine Earth without it. Mars comes to mind. No ocean, no life support system.

The ocean is our life support system. No blue, no green. It's really a miracle that we have got a place that works in our favor.

We are taking way more out of the ocean than the ocean can replenish.
