Planet Earth Quotes

“The earth itself assures us it is a living entity. Deep below surface one can hear its slow pulse, feel its vibrant rhythm. The great breathing mountains expand and contract. The vast sage desert undulates with almost imperceptible tides like the oceans. From the very beginning, throughout all its cataclysmic upthrusts and deep sea submergences, the planet Earth seems to have maintained an ordered rhythm.”

“The planet earth has a life span of eight billion years, give or take a few million. People have been around for approximately forty thousand years-a virtual blink in the cosmos. It is sad that we as a species are ravaging the natural world so fast that we are jeopardizing our survival. If we wipe ourselves out, it would be the height of folly, but the earth will survive even us. It will eventually restore itself. It might take a few thousand years, and it won't be just as it was before, but its life is stronger than death.”

“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.”

“If we can avoid disaster for the next two centuries, our species should be safe as we spread into space. If we are the only intellegent beings in the galaxy we should make sure we survive and continue. . . . Our only chance of long-term survival is not to remain inward looking on planet Earth but to spread out into space. We have made remarkable progress in the last hundred years. But if we want to continue beyond the next hundred years, our future is in space.”

“In order for life to have appeared spontaneously on Earth, there first had to be hundreds of millions of protein molecules of the Ninth Configuration. But, given the size of the planet Earth, do you know how long it would take for just one of these protein molecules to appear by chance? Roughly 10 to the 243rd power, billions of years; and I find that far, far more fantastic than simply believing in a god.”

“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.”
