Here's an excerpt from the book Jurassic Park which pretty much sums it all up. Although most people believe that the planet is in jeopardy, it is not. Our planet is four and a half billion years old. There has been life on this planet for nearly that long. 3.8 billion years. The first bacteria. And, later, the first multicellular animals, then the first complex creatures, in the sea, on the land. Then the great sweeping ages of animals - the amphibians, the dinosaurs, the mammals, each lasting millions upon millions of years. Great dynasties of creatures arising, flousishing, dying away. All this happening against a background of continous and violent upheaval, mauntain ranges thrust up and eroded away, cometary impacts, volcanic eruptions, oceans rising and falling, whole continents moving... Endless and constand and violent change... Even today, the greatest geographical feature on the planet comes from two great continents colliding, buckling to make the Himalayan mountain range over millions of years. The planet has survived everyting in its time. It will certainly survive us. "Just because it lasted a long time, doesn't mean it is permanent. If there was a radiation accident..." Suppose there was. Let's say we had a bad one, and all the plants and animals died, and the earth was clicking hot for a hundred thousand years. Life would survive somewhere - under the soil, or perhaps frozen in Arctic ice. And after all those years, when the planet was no longer inhospitable, life would again spread over the planet. The evolutionary process would begin again. It might take a few billion years for life to regain its present variety. And of course it would be very different from what it is now. But the earth would survive our folly. Life would survive our folly. Only we, think it wouldn't. "Well, if the ozone layer gets thinner - " There would be more ultraviolet radiation reaching the surface. So what? "Well, it'll cause skin cancer." Ultraviolet radiation is good for life. It is powerful energy. It promotes mutation, change. Many forms of life will thrive with more UV radiation. "And many other will die out." You think this is the first time such a thing has happened? Don't you know about oxygen? "I know that it is necessary for life." It is now, but oxygen is actually a metabolic poison. It's a corrosive gase, like flouring, which is used to etch glass. And when oxygen was first produced as a waste product by certain plant cells - say around 3 billion years ago - it created a crisis for all other life on our planet. Those plant cells were polluting the environment with a deadly poison. They were exhaling a lethal gas, and building up its concentration. A planet like Venus has less than one percent oxygen. On earth, the concentration of oxygen was going up rapidly - five ten, eventually twenty-one percent. Earthe had an atmosphere of pure poison! Incompatible with life! "So what is the point? That modern pollutants will be incorporated too?" No. The point is that life on earth can take care of itself. In the thinking of a human being, a hundred years is a long time. A hundred years ago, we didn't have cars and airplanes and computers and vaccines... It was a whole different world. But to the earth, a hundred years is nothing. This planet lives and breathes on a much vaster scale. We can't imagine its slow and powerful rhythms, and we haven't got the humility to try. We have been residents here for the blink of an eye. If we are gone tomorrow the earth will not miss us. "And we very well might be gone." Yes. We might. "So what are you saying? We shouldn't care about the environment?" No, ofcourse not. "Then what?" Let's be clear. The planet is not in jeopardy. We are in jepoardy. We haven't got the power to destroy the planet - or to save it. But we might have the power to save ourselves. Rather lengthy I will admitt, but I think it gets a point across. Let's face it ....the planet's gonna survive with, or with out us. The best we can do is to prolong it's livablility for our species.
