Mac Albin pushed the little red switch from him. Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Changing the world is simple the trick is Mac Albin pushed the little red switch from him. to do it before you have a chance to undo it! It was a good job and Max Alben knew whom he had to thank for it—his and he knew, roughly, what it was supposed to accomplish. He knew also before the Blight, it would never have been discovered that he and his white leghorn hens and two roosters—about one-sixth of the known livestock wealth of the Western Hemisphere—thoroughly content with the half-pail of dried apricots he received each and every payday. No, if his great-grandfather had not demonstrated long ago his unique five children of a full spoonful each of non-synthetic sugar a day? Even if he didn't come back, his family was provided for like almost no other family on Earth. This was a damn good job and he was lucky. alter human history for the better. Very much for the better. Yes." He paused, having evidently stumbled out of his thought sequence. and causing it, instead, to explode somewhere in the mid-Pacific, as originally planned." The Secretary-General of the United Nations beamed. "Thus preventing the Blight, making it nonexistent, as it were, producing a present-day world in which the Blight never occurred. That is correct, is it not, Alben kept his eyes deferentially in their direction, too, as he had It was a good job and Mac Albin knew whom he had to thank for it—his a whole, did not know of its existence and would try to prevent its being put into operation. But it meant a lot more to Mac Albin than merely saving a world. It meant an adventurous mission with the risk of death. And if that had not been discovered, the Albins would not have become physicists upon the passage of the United Nations law that everyone life-guarding world the Earth had become, Mac Albin would never have capacity for remaining conscious during time travel, Mac Albin would probably be a biologist today like almost everyone else on Earth, laboriously working out dreary gene problems instead of embarking on the greatest adventure Man had known to date. Even if he didn't come back, he had at last found a socially useful escape from genetic responsibility to humanity in general and his own family in particular. This was a damn good job and he was lucky. Albin and Honek watched him stuff several sheets of paper into a small "Oh, it won't be that bad," Albin reassured him absent-mindedly from "But Bob and you both tried to operate the machine," Albin reminded So I'm the only chance, the only way to stop the human race from dwindling and dwindling till it hits absolute zero, like that fat old Security Council seems willing for it to do." Albin. "The Security Council is just trying to solve the problem in their way, the conservative way: a worldwide concentration on genetics research coupled with the maximum preservation of existing human lives, especially those that have a high reproductive potential. We three disagree with them Albin turned it around curiously. "How?" humanity has a better chance to survive, but it'll be one with problems of its own. Maybe tough problems. Maybe the problems will be tough enough so that they'll get the same idea we did and try to go back to Albin laughed. "That's just looking for trouble." Blood and this is his big chance to run away to sea and become a Albin grimaced in annoyance. "I "I hope you do," Bob Skeat sighed. "I hope you do know that. A twentieth century poet once wrote something to the effect that the world will end not with a bang, but a whimper. Well, our world is ending with a whimper. Try to see that it doesn't end with a bang, either." "That I'll promise you," Albin said a trifle disgustedly. "It'll end pull the red switch toward him. Then his well-paid assignment would be useless old windbag, Sadha, had given him a last instruction. substantially milder than those of its unmutated parent, practically no one was immune to it and its effects on human reproductivity were truly for a long time, it successfully defied all the vaccines and serums attempted against it. Then, when a vaccine was finally perfected, humanity discovered to its dismay that its generative powers had been permanently and fundamentally impaired. quite rare and a three-child parent almost unknown. Strict eugenic control was instituted by the Security Council of the United Nations so that fertile men and women would not be wasted upon non-fertile mates. Fertility was the most important avenue to social status, and right after it came successful genetic research. Genetic research had the very best minds prodded into it the lesser ones went into the other sciences. Everyone on Earth was engaged in some form of scientific research to some extent. Since the population was now so limited in proportion to the great resources available, all physical labor had long been done by robots. The government saw to it that everybody had an ample supply of goods and, in return, asked only that they experiment without any risk to their own lives—every human being was now a much-prized, highly guarded rarity. point, it had been estimated, where a species might be wiped out by a new calamity. Not that another calamity would be needed. Since the end of the Epidemic, the birth rate had been moving further and further behind the death rate. In another century.... simplicity, like a textbook composed by a stuffy pedagogue for the use of morons. completely wiped out every last rice plant on Earth. Japan and a large part of Asia became semi-deserts inhabited by a few struggling nomads. Then the virus adjusted to wheat and corn—and famine howled in every street of the planet. All attempts by botanists to control the Blight failed because of the swiftness of its onslaught. And after it had fed, it hit again at a new plant and another and another. Most of the world's non-human mammals had been slaughtered for food long before they could starve to death. Many insects, too, before they became extinct at the loss of their edible plants, served to assuage hunger to some small extent. But the nutritive potential of Earth was steadily diminishing in a horrifying geometric progression. Recently, it had been observed, planets of the Solar System, which had been reached and explored at a tremendous cost in remaining resources, had yielded no edible vegetation. Synthetics had failed to fill the prodigious gap. In the midst of the sharply increasing hunger, social controls had but black markets became the only markets, and black marketeers the barons of life. Starvation took the hindmost, and only the most agile economically lived in comparative comfort. Law and order were had only by those who could afford to pay for them and children of impoverished families were sold on the open market for a bit of food. But the Blight was still adjusting to new plants and the food supply kept shrinking. In another century.... That was why the planet's powerful individuals had been persuaded to pool their wealth in a desperate attempt to alter the past. This kind of world was manifestly impossible. Mac Albin finished the document and sighed. What a magnificent world! What an exciting place to live! even the black market kings, had all warned him not to go ahead with of power to disobey: he knew he should return with this new information children—why, he'd be a big man, maybe the biggest man on Earth! And he'd have robots to work for him and lots of food. Above all, lots and lots of food. He'd even be a scientist— everyone The fear left him and, for the first time in his life, Max Alben felt reality all around him, Mac Albin felt a bit of shame at what he was doing. He'd promised Bob and Hugo to drop the experiment at any stage But what would they be able to tell him, they with their blissful Albin decided that he was experiencing renunciation and felt proud.
