...believe that the extremist view is held by those who are willing to tolerate the doubling of carbon dioxide in a single generation, the loss in a single lifetime of more than half the living species God put on earth, the destruction of a large percentage of the protective ozone shield in only a few decades, the loss of more than an acre of tropical rain forest every second, the addition of an entire China's worth of people every decade, the poisoning of our air and water resources, the serious erosion of our cropland. Those...
...will be a popular destination. According to scenarios worked out by a group of scientists who call themselves the Mars Underground, the first voyagers would be preceded by ferries carrying equipment for setting up a permanent base. Early visitors would face a hostile environment: a thin atmosphere of mostly carbon dioxide, temperatures that , fluctuate from -10 degrees F to -190 degrees F and hurricane winds. People would live chiefly underground, grow vegetables in greenhouses, wear space suits and explore the countryside in dirigibles...
...first step, according to one recent study, would be to warm the planet by releasing large amounts of chlorofluorocarbons into the atmosphere. These gases would act like a greenhouse, trapping the sun's heat. As the planet warmed, the polar caps would begin to melt, releasing water vapor and carbon dioxide into the Martian air, thickening it and increasing the greenhouse effect. Eventually the permafrost, where most of Mars' water is locked up, would melt, and rivers and lakes -- if not oceans -- would flow across the Red Planet again...
During the meditative session, the children regulate their breathing and fall into a trance. As Dr. Dean watches his computer screen, the levels of carbon dioxide and other wastes in their blood begin to drop. Blood pressure falls. Among the more advanced students, a surge of naturally induced biochemical relaxants sweeps through the blood vessels and permeates the body. Interferon levels begin to soar. Neurotransmitters in the brain return to normal. This is the effect that Dean and hundreds of other physicians before him have worked so hard to achieve. By harnessing the powers of the mind, the body...
