“And as I looked at the Earth, I also noticed that I could turn my head, and I could see the moon and the stars and the Milky Way galaxy. I could see our universe. And I could turn back, and I could see our beautiful planet.

And that moment changed my relationship with the Earth. Because for me the Earth had always been a kind of a safe haven, you know, where I could go to work or be in my home or take my kids to school. But I realized it really wasn’t that. It really is its own spaceship. And I had always been a space traveler. All of us here today, even tonight, we’re on this spaceship Earth, amongst all the chaos of the universe, whipping around the sun and around the Milky Way galaxy.”
