Passage Three
本文介绍了生态旅游对野生动物健康状况和它们的生存环境带来的负面影响。作者呼吁旅游者保护动物生存环境，有关部门加强对生态旅游的规范和管理。
The huge growth of global “ecotourism” industry is becoming an increasing concern for conservationists with mounting evidence that many wild species do not respond well to contact with human beings. Overexposure to tourists has been linked to stress, abnormal behaviour and adverse health effects in species such as polar bears, dolphins and gorillas(大猩猩)，says a report in New Scientist.
While regulated ecotourism can help conservation efforts by encouraging people to manage endangered species and their habitats, many projects are poorly designed and unregulated,① it says. “Many ecotourist projects are unaudited, unauthorized and merely hint they are based on environmentally friendly policies and operations.”②
Ecotourism is growing by 10 to 30 percent a year and an estimated 20 percent of tourists are thought to visit a conservation-based project. Philip Seddon, of the
“Transmission of disease to wildlife, or subtle changes to wildlife health through disturbance of daily routines or increased stress levels may translate to lowered survival and breeding,”④ he said. Research at the
In Africa, gorillas have picked up parasites introduced to their habitat by tourists and mongooses(蠓)have caught lung diseases from human beings. Experts said that the answer to the problems was better regulation and supervision of ecotourism. ⑤The Galapagos Islands, where visitor numbers are strictly controlled, is a good model.
Notes：
① endangered species 濒危物种habitats栖息地poorly designed and unregulated缺乏规划和无序管理。尽管有序的生态旅游有助于促使人们保护濒临灭绝的物种和它们的栖息地，但很多项目都是缺乏规划和无序管理的。
② unaudited未经审批的unauthorized未经许可的 hint 暗示，表示。
“许多生态旅游项目是未经审批的，未经许可的，这些项目只是模糊的暗示它们是按环境友好政策来进行运做的。
③…… 尽管大部分旅游项目依照基本规则利用土地并避免惊吓到野生动物，他们对野生动物造成的巨大影响却往往被忽视掉。
④“把疾病传染给野生动物，人类每日活动或给动物造成的生存压力引起野生动物健康的微妙变化，降低了野生动物的存活率和生育能力。”
⑤专家们说对于这个问题最好的解决方案只能是加强对生态旅游的规范和管理。
