A Quote by Stephen Hawking

One can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development. The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up. All of this is evidence that human exploitation of the planet is reaching a critical limit. But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land. There isn't any more available.

It is the hope of those who work toward the breakout from planet Earth that the establishment of permanent, self-sustaining colonies of humans off-Earth will ... make human life forever unkillable, removing it from the endangered species list, where it now stands on a fragile Earth overarmed with nuclear weapons. Second, the opening of virtually unlimited new land areas in space will reduce territorial pressures and therefore diminish warfare on Earth itself.

Gerard K. O'Neill

Life on Earth is at an ever-increasing risk of being wiped out by disaster. ... I think the human race doesn't have a future if it doesn't go into space. I therefore want to encourage public interest in space.

Peter Diamandis

Human activity is having a major impact on the planet. We consume or have diverted a large proportion of the productivity of the land and oceans. Our hunger for land crowds out fellow species. Our waste products pollute the waters, warm the atmosphere and acidify the oceans.

Ian Goldin

Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers. I think the human race has no future if it doesn't go into space. I therefore want to encourage public interest in space.

Stephen Hawking

To an observer situated on the moon or on one of the planets, the most noticeable feature on the surface of our globe would no doubt be the large areas covered by oceanic water. The sunlit face of the earth would appear to shine by the light diffused back into space from the land and water-covered areas.

C. V. Raman

Agriculture has become essential to life; the forest, the lake, and the ocean cannot sustain the increasing family of man; population declines with a declining cultivation, and nations have ceased to be with the extinction of their agriculture.

Elias Hasket Derby

Why limit yourself to the experience of your own relatively brief time on earth, according to your biological clock, when the whole realm of the human experience reaching back infinitely far is available to you?

David McCullough

Extrapolated, technology wants what life wants: Increasing efficiency Increasing opportunity Increasing emergence Increasing complexity Increasing diversity Increasing specialization Increasing ubiquity Increasing freedom Increasing mutualism Increasing beauty Increasing sentience Increasing structure Increasing evolvability

Kevin Kelly

We are paying for and even submitting to the dictates of an ever increasing, unceasingly spawning class of human beings who never should have been born at all-that the wealth of individuals and of state is being diverted from the development and the progress of human expression and civilization.

Margaret Sanger

Is the warming unprecedented? Probably not. There is abundant historical and proxy evidence for both hotter and cooler periods in human history. Is it our fault? Again, maybe. The correlation of increasing warmth with increasing carbon dioxide concentrations is particularly weak; that with solar energy and with ocean movements is much stronger.

Don Aitkin

To be able to rise from the earth; to be able, from a station in outer space, to see the relationship of the planet earth to other planets; to be able to contemplate the billions of factors in precise and beautiful combination that make human existence possible; to be able to dwell on an encounter of the human brain and spirit with the universe

Norman Cousins

If we look to the answer as to why for so many years we achieved so much, prospered as no other people on earth, it was because here in this land we unleashed the energy and individual genius of man to a greater extent than has ever been done before. Freedom and the dignity of the individual have been more available and assured here than in any other place on earth. The price for this freedom at times has been high, but we have never been unwilling to pay that price.

Ronald Reagan

It cannot be right in a world of increasing human progress - whether in medicine, space exploration or renewable energy - that so many people are denied the most basic human rights.

Paul Polman

The earth appears fragile and defenceless in the harsh environment of space and when one sees the amount of technology required to keep a human alive in that environment, one begins to feel blessed that one is an inhabitant of planet earth that supports human life.

Rakesh Sharma

Think about what it feels like when you interact with someone who makes you notice what's good about yourself (raising your status), who is clear with his expectations of you (increasing certainty), who lets you make decisions (increasing autonomy), who connects with you on a human level (increasing relatedness), and who treats you fairly.

David Rock

If the human species, or indeed any part of the biosphere, is to continue to survive, it must eventually leave the Earth and colonize space. For the simple fact of the matter is, the planet Earth is doomed... Let us follow many environmentalists and regard the Earth as Gaia, the mother of all life (which indeed she is). Gaia, like all mothers, is not immortal. She is going to die. But her line of descent might be immortal. . . . Gaia's children might never die out-provided they move into space. The Earth should be regarded as the womb of life-but one cannot remain in the womb forever.
