A Quote by Sylvia Earle
Earth as an ecosystem stands out in the all of the universe. There's no place that we know about that can support life as we know it, not even our sister planet, Mars, where we might set up housekeeping someday, but at great effort and trouble we have to recreate the things we take for granted here.

I began to learn about the universe myself and take it seriously. I know the names of the stars. I know how near or far the heavenly bodies are from our own planet. I know our own place in the universe. I can feel the vastness of it inside myself. I began to realize with each passing fact what a wonderful and awesome place the universe is, and that helped me in comics because I was looking for the awesome.
Life is a series of pulls back and forth. You want to do one thing, but you are bound to do somehing else. Something hurts you, yet you know it shouldn't. You take certain things for granted, even when you know you should never take anything for granted.
We know there are billions of stars and planets literally out there, and the universe is getting bigger. We know from our fancy telescopes that just in the last two years more than 20 planets have been identified outside our solar system that seem to be far enough away from their suns - - and dense enough - - that they might be able to support some form of life. So it makes it increasing less likely that we're alone. But if we were visited someday, I wouldn't be surprised.
I hope Let Me In doesn't encourage it! I mean, vampires might be real! Honestly, I don't know. It's like saying aliens are real. I don't know. We are so tiny in the spectrum of the universe, we're a speck of dust compared to some galaxies, and so who knows what's out there? We barely even know our own - we know more about space than we know about our own sea.
I should say we know that there are many, many other Earths out there. We're almost certain that there will be upwards of a billion Earth-like planets in our galaxy alone, so there is no lack of real estate where life might happen, but what we don't know is how likely it is given the real estate, given a wonderful pristine planet like Earth how likely is it that life will pop up inhabited? We don't know the answer to that.
The first men who set out for Mars had better make sure they leave everything at home in apple-pie order. They won't get back to earth for more than two and a half years. The difficulties of a trip to mars are formidable. . . . What curious information will these first explorers carry back from Mars? Nobody knows-and its extremely doubtful that anyone now living will ever know. All that can be said with certainty today is this: the trip will be made, and will be made . . . someday.
We are the most dangerous species of life on the planet, and every other species, even the earth itself, has cause to fear our power to exterminate. But we are also the only species which, when it chooses to do so, will go to great effort to save what it might destroy.
Mars, we know, was once wet and warm. Was it home to life? And what can living and learning to work on its rust-colored surface teach us about the future of our own planet, Earth? Answering those mysteries may hold the key to our future.
One of the things I do know is we know very little about our universe. Even though we think we know a lot, and we do know a lot more than we used to, we have a lot to learn about our universe.
So far as we know, Earth is the only planet which supports life, and it is the only planet on which we can survive. Our bodies and our minds are fashioned by it. Our hearts resonate with it. There will be little joy for the human spirit if we destroy the natural fabric of Earth with nothing left to do but go shopping. When we imagine the world a century from now, when we look our great grandchildren in the eye and see them smiling back at us because they know we cared for them, we smile too!
No planet is more earth-like than Earth itself, so if life really does pop up readily in earth-like conditions, then surely it should have arisen many times right here on our home planet? And how do we know it didn't? The truth is, nobody has looked.
When you are up there, feeling infinite space, the earth looks like a fragile planet against the immense universe. We are just another fleeting species, passing by. I do believe there is life elsewhere, and we are not alone. But not having found an alternate place for now, it is crucial to take care of the one place we do have.
People ask: Why should I care about the ocean? Because the ocean is the cornerstone of earth's life support system, it shapes climate and weather. It holds most of life on earth. 97% of earth's water is there. It's the blue heart of the planet - we should take care of our heart. It's what makes life possible for us. We still have a really good chance to make things better than they are. They won't get better unless we take the action and inspire others to do the same thing. No one is without power. Everybody has the capacity to do something.
The tension of opposites: Life is a series of pulls back and forth. You want to do one thing, but you are bound to do something else. Something hurts you, yet you know it shouldn't. You take certain things for granted, even when you know you should never take anything for granted. A tension of opposites, like a pull on a rubber band. And most of us live somewhere in the middle.
We are all . . . children of this universe. Not just Earth, or Mars, or this system, but the whole grand fireworks. And if we are interested in Mars at all, it is only because we wonder over our past and worry terribly about our possible future.
I thought about the earth then, really thought about it, the tsunami's and earthquakes and volcanoes, all the horrors I haven't witnessed but have changed my life, the lives of everyone I know, all the people I'll never know. I thought about life without the sun, the moon, stars, without flowers and warm days in May. I thought about a year ago and all the good things I'd taken for granted and all the unbearable things that had replaced those simple blessings. And even though I hated the thought of crying in from of Syl, tears streamed down my face.
