...trouble begins even before you enter the mausoleum that Emperor Shah Jahan built for his second wife, Queen Mumtaz Mahal. The crowds are huge (the site attracts 40% of the tourists who travel to India). And because authorities have banned fossil-fuel vehicles in the area, visitors must rent electric cars or carts drawn by horses or camels to get close to the mausoleum, even as flies swarm around the animals and the dung they scatter across the potholed roads...
...said President Bush believes the Kyoto treaty is "fatally flawed because it doesn't require developing countries to limit their fossil-fuel use immediately, as it does industrialized countries," and therefore he retreated from discussions in Bonn [NATION, Aug. 6]. Bush fails to acknowledge that most developing countries don't have the resources to implement dramatic change in their fuel-use policies right away. The U.S. clearly does, however, and we must do so first and set the example for the world. We can't expect the stretched economies of Third World countries to bear the burden of measures...
Vitousek is currently focusing on the problem of global nitrogen, the element that makes up 80% of the atmosphere. Nitrogen is also found in fossil-fuel exhaust and is a principal ingredient in fertilizer. Spread too much of it around, and it can throw off the planet's biological balance, triggering explosive growth in some species and suffocating others. "That's a huge alteration in how the world works," Vitousek says. "Our capacity to change the earth means we must manage this." For a man who didn't even much care for science at first, that's quite a mission...
...high school student, Andy Knoll was an avid fossil collector, but it never occurred to him that he would someday become a paleontologist. Where he came from, a small town near Reading, Pa., bright teenagers aspired to careers in medicine, law and, in Knoll's case, engineering. But one day while sitting in his dorm room at Lehigh University, Knoll realized that he hated engineering and loved biology and geology. That's when it hit him: as a paleontologist he could indulge his passion for both...
...technology works, but now the race is on to develop products and bring down costs to levels competitive with all things fossil fuel. "We're trying to do in a 10-year period what it took the internal-combustion engine 100 years to do," says Byron McCormick, director of General Motors' Global Alternative Propulsion Center. For GM and the other leading car manufacturers, it will take investments of hundreds of millions of dollars each to introduce mass-market hydrogen cars by 2010. The target: reduce costs of a fuel-cell engine...
