When you pack your bags for a big trip, you never know what's in store for you. The Apollo astronauts on their way to and from the Moon photographed their home planet. It was a natural thing to do, but it had consequences that few foresaw. For the first time, the inhabitants of Earth could see their world from above — the whole Earth, the Earth in color, the Earth as an exquisite spinning white and blue ball set against the vast darkness of space. Those images helped awaken our slumbering planetary consciousness. They provide incontestable evidence that we all share the same vulnerable planet. They remind us of what is important and what is not. They were the harbingers of Voyager's pale blue dot.

An extraterrestrial being, newly arrived on Earth - scrutinizing what we mainly present to our children in television, radio, movies, newspapers, magazines, the comics, and many books - might easily conclude that we are intent on teaching them murder, rape, cruelty, superstition, credulity, and consumerism. We keep at it, and through constant repetition many of them finally get it.

Hablamos de ganar y perder una guerra con la misma naturalidad con que se habla de ganar y perder un partido. En un anuncio televisivo del ejército norteamericano aparece un carro de combate que destruye a otro en unas maniobras, después de lo cual el jefe del vehículo victorioso dice: «Cuando ganamos, no gana una sola persona, sino todo el equipo.» La relación entre deporte y combate resulta por demás clara. Los fans (abreviatura de «fanáticos») llegan a cometer toda clase de desmanes, incluso a matar, cuando se sienten vejados por la derrota de su equipo, se les impide celebrar la victoria o consideran que el arbitro ha cometido una injusticia.
