Those worlds in space are as countless as all the grains of sand on all the beaches of the earth. Each of those worlds is as real as ours and every one of them is a succession of incidents, events, occurrences which influence its future. Countless worlds, numberless moments, an immensity of space and time. And our small planet at this moment, here we face a critical branch point in history, what we do with our world, right now, will propagate down through the centuries and powerfully affect the destiny of our descendants, it is well within our power to destroy our civilization and perhaps our species as well. If we capitulate to superstition or greed or stupidity we could plunge our world into a time of darkness deeper than the time between the collapse of classical civilization and the Italian Renaissance. But we are also capable of using our compassion and our intelligence, our technology and our wealth to make an abundant and meaningful life for every inhabitant of this planet.

Science Fiction has long been babbling about cosmic destructions and the ending of either physical or civilized worlds, but it has all been displaced babble. SF has been carrying on about near-future or far-future destructions and its mind-set will not allow it to realize that the destruction of our world has already happened in the quite recent past, that today is "The Day After The World Ended". ... I am speaking literally about a real happening, the end of the world in which we lived till fairly recent years. The destruction or unstructuring of that world, which is still sometimes referred to as "Western Civilization" or "Modern Civilization", happened suddenly, some time in the half century between 1912 and 1962. That world, which was "The World" for a few centuries, is gone. Though it ended quite recently, the amnesia concerning its ending is general. Several historiographers have given the opinion that these amnesias are features common to all "ends of worlds". Nobody now remembers our late world very clearly, and nobody will ever remember it clearly in the natural order of things. It can't be recollected because recollection is one of the things it took with it when it went...

We are only seeking Man. We have no need of other worlds. We need mirrors. We don't know what to do with other worlds. A single world, our own, suffices us; but we can't accept it for what it is. We are seaching for an ideal image of our own world: we go in quest of a planet, of a civilisation superior to our own but developed on the basis of a prototype of our primeval past. At the same time, there is something inside us which we don't like to face up to, from which we try to protect ourselves, but which nevertheless remains, since we don't leave Earth in a state of primal innocence. We arrive here as we are in reality, and when the page is turned and that reality is revealed to us — that part of our reality which we would prefer to pass over in silence — then we don't like it any more.
Stanislaw Lem
The choice is with us still, but the civilization now in jeopardy is all humanity. As the ancient myth makers knew, we are children equally of the earth and the sky. In our tenure on this planet we've accumulated dangerous evolutionary baggage — propensities for aggression and ritual, submission to leaders, hostility to outsiders — all of which puts our survival in some doubt. But we've also acquired compassion for others, love for our children and desire to learn from history and experience, and a great soaring passionate intelligence — the clear tools for our continued survival and prosperity. Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the immensity of the Cosmos, an inescapable perspective awaits us. There are not yet any obvious signs of extraterrestrial intelligence and this makes us wonder whether civilizations like ours always rush implacably, headlong, toward self-destruction. National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national chauvinisms are a little difficult to maintain when we see our planet as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and citadel of the stars. Travel is broadening.
Carl Sagan
Each moment in history is a fleeting time, precious and unique. But some stand out as moments of beginning, in which courses are set that shape decades or centuries.
This can be such a moment.
Forces now are converging that make possible, for the first time, the hope that many of man's deepest aspirations can at last be realized. The spiraling pace of change allows us to contemplate, within our own lifetime, advances that once would have taken centuries.
In throwing wide the horizons of space, we have discovered new horizons on earth.
For the first time, because the people of the world want peace, and the leaders of the world are afraid of war, the times are on the side of peace.Richard Nixon
Our intelligence and our technology have given us the power to affect the climate. How will we use this power? Are we willing to tolerate ignorance and complacency in matters that affect the entire human family? Do we value short-term advantages above the welfare of the Earth? Or will we think on longer time scales, with concern for our children and our grandchildren, to understand and protect the complex life-support systems of our planet? The Earth is a tiny and fragile world. It needs to be cherished.
