       A  new study shows an eighty percent decrease of hard coral in the Caribbean Sea over the past thirty years. Scientists from Britain's University of East Anglia and the Tyndall Center For Climate Change Research did the study. They published their findings in Science magazine.
      一项新的研究表明,在过去的三十年里,加勒比海的硬质珊瑚数量减少了80%。来自英国东英格兰大学和 庭德尔气象变化研究中心的科学家们一起进行了这项研究,并在《科学》杂志上发表了他们的发现。
        Coral is made up of hundreds to hundreds of thousands of organisms called polyps. Each is covered with cells  filled with poison.The coral uses the pison to defend itself and to capture its food. Hard coral covers reefs. Soft coral, like sponges and sea fans, live on hard coral.
        珊瑚是由成千上万名叫珊瑚虫的有机体构成。每个珊瑚都覆盖着有毒机体。它们就是用毒来保护自己并捕获猎物的。硬质珊瑚生长在暗礁上。海绵,海扇一类的软质珊瑚靠硬质珊瑚生活。
        In the nineteen-seventies, hard coral covered about fifty percent of the average reef in the  Caribbean. Today, the researchers say, the cover is down to ten percent. They say it appears nothing like this has happened before for at least three-thousand years.
       在 二十世纪七十年代,加勒比海约50%的暗礁上都生长着硬质珊瑚。而今,据研究人员说这种覆盖率已经降低到了10% 。他们说至少三千年内没有发生过这类事情。
       Ocean biologist Isabelle Cote took part in the study. She says the scientists knew there were serious problems with the Caribbean reef system, but what they found surprised them. they bassed their findings on sixty -five earlier studies that examined more than two hundred sixty areas of reef in the Caribbean Sea.
        海洋生物学家贝尔.?考特参与了这项研究。她说尽管科学家已经知道加勒比海的暗礁生态系统存在严重的问题,但是这个发现还是令他们震惊。他们在早期的六十五项研究中检查了加勒比海的二百六十多个暗礁区域,现在的发现就是以此作为基础的。

         A first, the scientists were trying to learn rhe amount of destruction that ocean storms had caused to coral reefs over the  years. But the researchers decided they had to expand their study. Ms. Cote says they needed to be able to compare storm damage with damage from other forces.
        最初,科学家们试着了解多年以来海洋风暴对珊瑚暗礁的大量破坏。但是研究员们决定拓展他们的研究。考特女士说他们需要对比风暴和其他因素对珊瑚暗礁的破坏。
         The study found that wearher conditions have played a part in the decrease of Caribbean coral. But thr scientists say human activity has been at least as destructive. Catching too many fish is one problem.  Fish eat plants that live on coral. The fish help keep a balance in the plant life. When too many fish are caught, some plants may spread too fast and kill the coral. Pollution is also a problem. So too is the flow of soil into rivers that feed the sea. This includes soil from forests that have been cut down. It takes thousands of years for coral cells to build  a reef. Scientists say healthy reef are not only important for nature. The many different kinds of sea life may also provide materials for new medicines. The scientists who did the study say there are signs of recovery in some areas of the Caribbean. But they say they do not know if this new coral will be able to survive any better.
         研究发现天气条件是影响加勒比海珊瑚数量下降 因素之一。但是,科学家说至少人类的活动也是破坏性的。过度捕鱼就是一个问题。鱼以靠珊瑚生存的植物当粮,所以能够帮助维护植物生命的平衡。过量的鱼被捕获后,一些植物就可以大量滋生,扼杀珊瑚的生存。污染也是问题之一。土壤流失到到江河,再汇入大海也是个问题。这其中也包括了来自于被砍伐过的森林的土壤。珊瑚虫形成珊瑚礁需要上千年的时间。科学家们说好的暗礁不只对自然界很重要,不同种类的海洋生物也为新的药品提供原材料。做这项研究的科学家们说,在加勒比海的某些地区,珊瑚礁的数量有上升的迹象。但是他们也不知道这种新的珊瑚能否更好的生存下去。
