...RACE, blood levels of nitrogen and protein waste products--and those of potassium, sodium and other substances not normally found there--are rising. Rusch knows too well what that feels like. "You're just in this state of slow deterioration, and you're doing everything you can to buy time," she says. "You can't recover until you stop." Even then, say exercise physiologists, the body doesn't always bounce back completely. Ultra-athletes may be more susceptible to developing arthritis and fractures when they are older, and their muscles may not recover as quickly from tears and bruises. Still...
...some combination of dirty air and polluted water (both surface and sub-surface) with complex consequences for both human and ecosystem health. It was relatively easy to associate cause with effect. Burning coal adds large concentrations of sooty materials to the atmosphere, in addition to gaseous compounds of nitrogen and sulfur oxides and a variety of toxic elements including, for example, mercury. The effluents from coal burning have a demonstrably negative effect on human health. It took a series of air pollution disasters, however, in Donora, Penn., and in London in the late 1940s and early 1950s before public opinion...
...since the building of the Alaska oil pipeline has a construction project posed more daunting challenges. In parts of the desert where daytime temperatures reach a scorching 120° F, work shifts began under lights at midnight, and liquid nitrogen was used to cool some of the 2.1 million cu. yds. of concrete poured. To allay environmental concerns, engineers built walkways across parts of the canals for the use of cattle and mule deer, and aqueduct sides were deliberately made rough to lend footing for smaller animals that might climb down for a drink. Human visitors are not welcome...
When our village meeting got under way, I canvassed the group and got very perceptive accounts of the grim situation. Only two of the 200 farmers at the meeting reported using fertilizer at present. Around 25% are using improved fallows with nitrogen-fixing trees, a scientific farming approach developed and introduced into Sauri by the World Agroforestry Center. With this novel technique, villagers grow trees that naturally return nitrogen to the soil by converting it from the atmosphere, thus dramatically improving yields. The new method could be used throughout the village if more money were available for planting the trees...
...Seeing Red A Danish biotech company has developed a new way to detect land mines using genetically modified THALE CRESS, a member of the mustard family. The plant turns a deep red when exposed to nitrogen dioxide, a gas released by mines. The grow-anywhere green, which scientists propose to sow from airplanes or handheld seed-shooters in heavily mined areas, could prove an inexpensive and safe solution for land mine detection?a boon to countries like Cambodia, which harbors an estimated four million mines...
