In this adjustment, a day equals something like seven hundred and fifty million years, and thus “all day Monday and until Tuesday noon creation was busy getting the earth going.” Life began Tuesday noon, and “the beautiful, organic wholeness of it” developed over the next four days. “At 4 P.M. Saturday, the big reptiles came on. Five hours later, when the redwoods appeared, there were no more big reptiles. At three minutes before midnight, the human race appeared. At one-fourth of a second before midnight, Christ arrived. At one-fortieth of a second before midnight, the Industrial Revolution began. We are surrounded with people zakelijke energie who think that what we have been doing for that one-fortieth of a second can go on indefinitely. They are considered normal, but they are stark raving mad.” Brower holds up a photograph of the world -blue, green, and swirling white. “This is the sudden insight from Apollo,” he says. “There it is. That’s all. We see through the eyes of the astronauts how fragile our life really is.” Brower has computed that we are driving through the earth’s resources at a rate comparable to an automobile going a hundred and twenty-eight miles an hour-and he says that we are accelerating. In like manner, geologists will sometimes use the calendar year as a unit to represent the time scale, and in such terms the Precambrian runs from New Year’s Day until well after Halloween. Dinosaurs appear in the middle of December and are gone the zakelijke energie vergelijken day after Christmas. The last ice sheet melts on December 31st at one minute before midnight, and the Roman Empire lasts five seconds. With your arms spread wide again to represent all time on earth, look at one hand with its line of life. The Cambrian begins in the wrist, and the Permian Extinction is at the outer end of the palm. All of the Cenozoic is in a fingerprint, and in a single stroke with a mediumgrained nail file you could eradicate human history. Geologists live with the geologic scale. Individually, they may or may not be alarmed by the rate of exploitation of the things they discover, but, like the environmentalists, they use these repetitive analogies to place the human record in perspective-to see the Age of Reflection, the last few thousand years, as a small bright sparkle at the end of time.
