We are dependent not so much on Earth, the third planet orbiting the sun, as on Gaea, the integrated system that includes, sustains and is shaped by life.
We are, many of us, a planet orbiting somebody's sun, unconscious of a lonely moon, orbiting our planet.
Science has an uncomfortable way of pushing human beings from center stage. In our prescientific stories, humans began as the focal point of Nature, living on an Earth that was the center of the universe. As the origins of the Earth and of mankind were investigated more carefully, it became clear that Nature had other interests beyond people, and the Earth was less central than previously hoped. Humankind was just one branch of the great family of life, and the Earth is a smallish planet orbiting an unexceptional sun quite far out on one arm of a run-of-the-mill spiral galaxy.
Do you ever wonder if--well, if there are people living on the third planet?' 'The third planet is incapable of supporting life,' stated the husband patiently. 'Our scientists have said there's far too much oxygen in their atmosphere.
Every child's bedroom is as important as a telescope orbiting the planet earth or a philosopher's study.
Our astronauts, when they go orbiting around the earth, they actually come back slightly younger than a twin that they would have on the planet Earth who was stationary. This is called the twin paradox.
This is my year of transition from what I'm calling the second phase of my life to the third phase of my life. And I wanted to pass it along. What I mean by that is, in the first days of your life you're dependent on others and you learn. You're basically a kid, depending on your parents. In the second phase of your life, you're working and others are dependent on you and you're trying to be successful. And then when you go to the third phase of your life it's no longer as much of a kick to be successful. There's a natural, instinctual desire to help other people be successful.
Days begin and end in the dead of night. They are not shaped long, in the manner of things which lead to ends - arrow, road, man's life on earth. They are shaped round, in the manner of things eternal and stable - sun, world, God.
The light from the sun breaks through space, bathing our planet as it encircles the sun with life-giving warmth and light. Without the sun, there could be no life on this planet; it would be forever barren, cold, and dark.
One of the reasons we're here, that we exist at all, is that Earth, cosmically speaking, is in a relatively peaceful place: orbiting our Sun in a near perfect circle.
Human consensus does not generate reality. Were it able to do so, the Sun would have taken to orbiting the Earth some time ago.
Look at that! If you ever needed convincing that we live in the solar system, that we are on a ball of rock, orbiting around the Sun with other balls of rock, then look at that! That's the solar system coming down and grabbing you by the throat.
And then, the Earth being small, mankind will migrate into space, and will cross the airless Saharas which separate planet from planet and sun from sun. The Earth will become a Holy Land which will be visited by pilgrims from all the quarters of the Universe. Finally, men will master the forces of Nature; they will become themselves architects of systems, manufacturers of worlds.
Forests ... are in fact the world's air-conditioning system-the very lungs of the planet-and help to store the largest body of freshwater on the planet ... essential to produce food for our planet's growing population. The rainforests of the world also provide the livelihoods of more than a billion of the poorest people on this Earth... In simple terms, the rainforests, which encircle the world, are our very life-support system-and we are on the verge of switching it off.
I cannot possibly conceive of my planet Earth as the centre of a three-tiered universe. I know rather that the sun, around which my planet Earth revolves, is a middle sized star in a galaxy called the Milky Way that has over a hundred billion other suns or stars within it.
We are putting value in the things that really are not valuable, things like commodities or disposable stuff that can bought, but the rainforest has been undervalued, because the value shouldn't be in the trees that you take out; it's should be with leaving the trees to preserve the life system that sustains life on the planet.
Humankind has suddenly entered into a brand new relationship with our planet. Unless we quickly and profoundly change the course of our civilization, we face an immediate and grave danger of destroying the worldwide ecological system that sustains life as we know it.
