Look again at that (blue) dot (Earth seen from space). That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you have ever heard of, every human being who ever was, lived out their lives...There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.
