During her childhood, Rachel showed an interest in nature and in writing. After high school, she entered Pennsylvania State College for women, aiming at becoming a writer. She switched to biology, however, thus setting the course of her life. Rachel went to Johns Hopkins University for further study and became a member of the zoology(动物学)staff at the University of Maryland. For fif years, Rachel worked for the United States Fish and Wildlife Service, writing and editing publications. Fortunately, her employer encouraged her to reach a larger audience. Rachel’s poetic style of writing in three books about the ocean caught the imagination of the general reader. Her rare talent as both a physical scientist and a gifted writer earned her the National Book Award for the Sea Around Us. Rachel’s next book marked her as a leading fighter for the preservation of the natural environment. She began writing Silent Spring, knowing that she would be personally attacked and ridiculed. She continued writing despite the ill health that slowed her progress. Upon completing the book, she wrote to a close friend, "I have felt obliged to do what I could if I didn’t at least try I could never again be happy in nature. But now I believe I have at least helped a little. " Rachel Carson did more than help a little. Although both government and industry opposed her, specialists in public health, the press, and the public itself all supported her fight against the irresponsible use of insecticides(杀虫剂). Her book ually led the government to ban DDT.When scientists consider the possible effects of global warming, there is a lot they don’t know. But they can say one thing for sure: sea levels will rise. This rising water will be felt along the artificially maintained beaches of New Jersey, in the vanishing marshes of Louisiana, even on the ocean cliffs of California. According to a 2000 report by the Heinz Center for Science, Economics and the Environment, at least a quarter of the houses within 500 feet of the United States coast may be lost to rising seas by 2060. There were 350, 000 of these houses when the report was written, but today there are far more. Though most of the country’s ocean beaches are eroding, few coastal jurisdictions(管辖权)consider sea level rise in their coastal planning, and still fewer incorporate the fact that the rise is accelerating. Instead, they are sticking with policies that geologists say may help them in the short term but will be untenable(站不住脚的)or even destructive in the future. Florida is a good example. To prepare for hurricane season, which began on June 1 and has already brought Tropical Storm Alberto, Floridians were still repairing storm damage from 2005 and even 2004, building or repairing walls to shield beachfront buildings. Until May 1, when turtle nesting season forced them to stop, they were also pumping hundreds of thousands of cubic yards of sand onto eroded beaches. Florida has relied on this approach for decades, but after the past few storm seasons, there has been an increase in applications for sea wall permits, many from Mr. Tomasello’s s. "If you have a house or a condo(集合公寓)that’s threatened, it’s really the only alternative, " he said. Maintaining eroding beaches with artificial infusions of sand is difficult and costly, and as sea levels rise, it may become economically impractical or even impossible. "The combination of sea walls and rising sea level will accelerate the rate of land loss in front of those sea walls", said Peter Howd, an oceanographer who conducts shoreline research for the United States Geological Survey in St. Petersburg. "So people with a sea wall and a beach in front of it will end up with just a sea wall.
