Lucky you have a job in demolition. It's slow and dirty work, but steady. The fading structures of a decaying city are the great mineral mines and hardware shops of the nation. Break them down and reuse the parts. Coal is too difficult to dig up and transport to give us energy in the amounts we need, nuclear fission is judged to be too dangerous, the hoped-for breakthrough toward nuclear fusion never took place, and solar batteries are too expensive to maintain in sufficient quantity. Anyone older than ten can remember automobiles. At first, the price of gasoline climbed—way up. Finally, only the well-to-do drove, and that was too clear an indication that they were filthy rich; so any automobile on a city street was overturned and burned. The cars vanished, becoming part of the metal resource. There are advantages in 1997, if you want to look for them. The air is cleaner, and there seem to be fewer cold. The crime rate has dropped. With the police car too expensive, policemen are back on their beats. More important, the streets are full. Legs are king, and people walk everywhere far into the night. There is mutual protection in crowds. If the weather isn't too cold, people sit out front. If it is hot, the open air is the only air conditioning they get. At least the street lights still burn. Indoors, few people can afford to keep light burning after supper. As for the winter—well, it is inconvenient to be cold, with most of what furnace fuel is allowed hoarded for the dawn. But sweaters are popular indoor wear. Showers are not an everyday luxury. Lukewarm sponge baths must do, and if the air is not always very fragrant in the human vicinity, the automobile fumes are gone. It is worse in the suburbs, which were born with the auto, lived with the auto, and are dying with the auto. Suburbanites form. associations that assign turns to the procurement and distribution of food. Pushcarts creak from house to house along the posh suburban roads, and every bad snowstorm is a disaster. It isn't easy to hoard enough food to last till the roads are open. There is not much refrigeration except for the snow-banks, and then the dogs must be fought off. What energy is left must be conserved for agriculture. The great car factories make trucks and farm machinery almost exclusively. The American population isn't going up much anymore, but the food supply must be kept high even though the prices and difficulty of distribution force each American to eat less. Food is needed for export to pay for some trickles of oil and for other resources. The rest of the world is not as lucky as we are. They're starving out there because earth's population has continued to rise. The population on earth is 5.5 billion—up by 1.5 billion since 1977—and, outside the United States and Europe, not more than one in five has enough to eat at any given time. There is a high infant mortality rate. It's more than just starvation, though. There are those who manage to survive on barely enough to keep the body working, and that proves to be not enough for the brain. It is estimated that nearly two billion people in the world are permanently brain-damaged by undernutrition, and the number is growing. At least the big armies are gone. Only the United States and the Soviet Union can maintain a few tanks, planes, and ships—which they dare not move for fear of biting into limited fuel reserves. Machines must be replaced by human muscle and beasts of burden. People are working longer hours, and—with lighting restricted, television only three hours a night, new books few and printed in small editions—what is there to do with leisure？ Work, sleep, and eating are the great trinity A．a scientific study of life in 1997 B．an imaginary account of life in 1997 C．a history of life in 1997 D．a difficult time of life in 1997
