...opposite sides of the world last week two veteran paleontologists reported two remarkable fossil finds that could literally be described as superlative. One discovery may well qualify as the "largest," the other as the "oldest...
Wakefield's colleagues at first showed disbelief, since the earliest fossil evidence of limbed vertebrates in the Southern Hemisphere dates back only 230 million years. But the skeptics were convinced when Wakefield later found in the same area plant fossils that clearly dated back to the same period, often called the Age of Fishes, during which the first primitive amphibians edged their way toward land...
...their 83 million cars, more kerosene to thrust their jet fleets faster, more coal to fire the boilers of industry, more natural gas to heat their homes in winter, more electricity to cool them in summer. The U.S. now burns up the equivalent of 1.9 billion tons of fossil fuel every year (30% of the world's consumption) but produces only 1.7 billion tons-and the gap is widening. It must import the rest. Says S. David Freeman, former energy expert for Presidents Johnson and Nixon: "Our rates of consumption are so large that we can see the bottom...
...however, fuel supplies are al ready becoming scarcer, harder to dig out and thus more expensive. The focal point of this energy crisis-the point at which demand is growing fastest and threatening most immediately to out strip available supplies-is in electric power, which is largely derived from fossil fuels (oil, coal...
Less than a century has passed since Thomas Edison first opened his Pearl Street Station to supply 85 New Yorkers with incandescent light. By 1920 the U.S. was producing 40 billion kw-h of electricity. Today it takes 25% of all its fossil fuels (plus some fissionable uranium) and produces 1.6 quadrillion kwh, or 34% of the world's output. The largest share of this power (40% ) goes to industry; the rest is split mostly be tween commercial (22%) and residential (34%) uses...
