[EX Q]: Article: Have you ever imagined what the world will be in the near future? A recent study shows that the world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in now. Visible ahead is serious stress involving population, resource and environment. Despite greater food output, people in the world will be poorer in many ways than they are today. For hundred of millions of the extremely poor, the outlook for food and other necessities of life will be no better, for many it will be worse. While the economies of the developing countries are expected to grow at a faster rate than those of the industrialized nation, the total national product per head in most less developed countries remains low. The existing gap between the rich and poor nations will further widen. World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase goes to the countries that already have higher per-head food consumption. Meanwhile, per-head consumption of food in the developing countries will scarcely improve or will actually fall far below the present inadequate level. What is worse is that prices for food are expected to double. As a result, many less developed countries will have increasing difficulties meeting energy needs. For the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful. Regional water shortage will become more sever. In the 1970-2100 period population growth will require twice as much water as it does today in nearly half the world. Still greater increases would be needed to improve standards of living. Development of new water supply will become more costly.

[EX Q]: Article: My 16-year-old son, Anton, had gone to the local swimming hole. Most of the kids who swim there are fit and strong teens, and there are plenty of rocks for them to use as safe harbors, so I had no fears for his well-being. Still, the firefighter's first words, "You need to come up here to the Stillwater River," made me catch my breath. When I got to the river, I saw Anton sitting quietly on a low platform of the fire engine, with a towel wrapped about his shoulders. I hurried over to him. "You OK?" I asked. "Yeah," was all he said. But my eyes begged for an explanation. I didn't get it from my son. The story was this: A couple in their 20s, unfamiliar with the Stillwater, had gotten caught in the current and began screaming for help. Without hesitation Anton and his friend dived into the water, swam out to the drowning woman, and brought her safely to shore. In an age in which the world "hero" is broadcast with abandon and seemingly applied to anyone, I realized the real thing in my son and his friend--the disregarding of personal safety for the sake of another human being. I know that teens are headstrong and self-centered, but this didn't lower the gravity of the event and the desire to do good. Along the way home I tried to get some more information from him, but the only words were, "What's for supper?" I thought twice about the tragedy that might have been. Questions flew across my mind like a flight of swallows: Would I have risked my life to save a drowning person? Or would I have chosen to dial 911? Would I have told the story over and over to anyone who'd listen? The next morning, when Anton got up, I half expected him to tell me the story from his point of view, now that he had some distance from the event. But all he did was to toast a pie, pull himself together, and head for the door to begin the new day.
