Spaceship Earth is a world view term usually expressing concern over the use of limited resources available on Earth and the behavior of everyone on it to act as a harmonious crew working toward the greater good.
It is a well-provisioned ship, this on which we sail through space. If the bread and beef above decks seem to grow scarce, we but open a hatch and there is a new supply, of which before we never dreamed. And very great command over the services of others comes to those who as the hatches are opened are permitted to say, "This is mine!"
In 1965 Adlai Stevenson made a famous speech to the UN in which he said:
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.
The following year, Spaceship Earth became the title of a book by a friend of Stevenson's, the internationally influential economist Barbara Ward.
Also in 1966 Kenneth E. Boulding used the phrase in the title of an essay, The Economics of the Coming Spaceship Earth. Boulding described the past open economy of apparently illimitable resources, which he said he was tempted to call the "cowboy economy", and continued: "The closed economy of the future might similarly be called the 'spaceman' economy, in which the earth has become a single spaceship, without unlimited reservoirs of anything, either for extraction or for pollution, and in which, therefore, man must find his place in a cyclical ecological system". (David Korten would take up the "cowboys in a spaceship" theme in his 1995 book When Corporations Rule the World.)
The phrase was also popularized by Buckminster Fuller, who published a book in 1968 under the title of Operating Manual for Spaceship Earth. This quotation, referring to fossil fuels, reflects his approach:
"...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."
United Nations Secretary-General U Thant spoke of Spaceship Earth on Earth Day March 21, 1971 at the ceremony of the ringing of the Japanese Peace Bell: "May there only be peaceful and cheerful Earth Days to come for our beautiful Spaceship Earth as it continues to spin and circle in frigid space with its warm and fragile cargo of animate life."
David Deutsch has pointed out that the picture of Earth as a friendly "spaceship" habitat is difficult to defend even in metaphorical sense. The Earth environment is harsh and survival is constant struggle for life, including whole species extinction. Humans wouldn't be able to live in most of the areas where they are living now without knowledge necessary to build life-support systems such as houses, heating, water supply etc.
