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.

We are blessed with a place that is open to the universe and, despite this, supports this very thin envelope of air we call atmosphere, which holds just the right amount of oxygen for us to breathe.

We must protect our ocean as if our lives depend upon it, because they do.

What we put into the atmosphere in terms of burning fuel is unprecedented.

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.

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

We have the capacity to alter the nature of nature. No, we don't have just the capacity - we are altering the nature of nature, the natural systems that cause the planet to function in our favor.
