...will be a slow, carefully monitored journey. First, 6 million cu. ft. of nitrogen will be blown through the pipeline to purge air from the system, reducing the threat of oil-vapor explosions. Next, a cylindrical plug, called a "pig," will be shoved into the line. Finally, after a signal from Valdez, workmen will open valves at Prudhoe, allowing long-capped crude to fill the line behind the pig. The moving oil will push the pig through the 48-in.-diameter steel pipe at 1 m.p.h. As it goes, the cylinder will shove out of the pipe any refuse that...
...accelerating use of nitrogen fertilizers, which are converted by bacteria into nitrogen oxides that eventually rise into the stratosphere, could result in the destruction of as much as another 15% of the ozone layer. Most disastrous would be a large-scale nuclear war, which would blast enough nitrogen oxides into the atmosphere to reduce the ozone layer by as much as 70% for a period of from five to ten years. Even a slight increase in ultraviolet rays seems to cause a higher incidence of skin cancer, and a significant depletion of the ozone layer could cause far-reaching damage...
...last ones will go into 1983 Corvettes. Only one-third of GM's 1985 cars will even have six-cylinder engines; two-thirds will have four-cylinder power plants. Diesel engines will drive 25% of the company's fleet, at least if the regulations on how much nitrogen oxide they can pour into the air are not tightened further. Diesels are noisy, smoky and heavier than gasoline engines, but they burn less fuel...
...evil. Proponents of this research in DNA-the master molecule of life-are convinced that it can help point the way toward a new promised land-of understanding and perhaps curing cancer and such inherited diseases as diabetes and hemophilia; of inexpensive new vaccines; of plants that draw their nitrogen directly from the air rather than from costly fertilizers; of a vastly improved knowledge of the genetics of all plants and animals, including eventually even humans (TIME special section, April...
...that was scrapped in 1971. There were prophecies that supersonic aircraft would emit such great quantities of water vapor that a permanent cloud barrier would shut out the sun; this "greenhouse" effect would dangerously raise the earth's surface temperature. There were also predictions of skin cancer epidemics: nitrogen oxides released by the SSTs would destroy the ozone layer that partly shields the earth against the sun's lethal ultraviolet radiation. Then too, the SST's fumes were denounced as a potential new cause of massive pollution...
