We travel together, passengers on a little space ship, dependent on its vulnerable reserves of air and soil; all committed for our safety to its security and peace; preserved from annihilation only by the care, the work, and, I will say, the love we give our fragile craft. We cannot maintain it half fortunate, half miserable, half confident, half despairing, half slave—to the ancient enemies of man—half free in a liberation of resources undreamed of until this day. No craft, no crew can travel safely with such vast contradictions. On their resolution depends the survival of us all. -Adlai Stevenson
… we can make all of humanity successful through science’s world-engulfing industrial evolution provided that we are not so foolish as to continue to exhaust in a split second of astronomical history the orderly energy savings of billions of years’ energy conservation aboard our Spaceship Earth. These energy savings have been put into our Spaceship’s life-regeneration-guaranteeing bank account for use only in self-starter functions.
– Buckminster Fuller
Like a grand and miraculous spaceship, our planet has sailed through the universe of time, and for a brief moment, we have been among its many passengers… We now have the ability and the responsibility to build new bridges of acceptance and co-operation between us, to create a better world for ourselves and our children as we continue our amazing journey aboard Spaceship Earth. –Jeremy Irons
