2024考研英语同源外刊:外来物种造成全球经济损失
Human activity – often through travel or global trade – is spreading these animals, plants and other organisms in new regions at an “unprecedented rate,” with 200 new alien species being recorded every year, leading scientists said. Of 37.000 alien species known to have been introduced around the world, 3.500 are considered harmful and pose a “severe global threat” by destroying crops, wiping out native species, polluting waterways, spreading disease and laying the groundwork for devastating natural disasters.
科学家们表示，旅行或全球贸易中的人类活动正以“前所未有的速度”将这些动植物和其他生物带到新的地方，每年有200个新的外来物种被记录下来。在世界各地已知的3.7万个外来物种中，有3500个被认为是有害的，它们破坏农作物、灭杀本地物种、污染水道、传播疾病，并为毁灭性的自然灾害奠定了基础，构成了“严重的全球威胁”。
The global economic cost is tremendous, scientists say, having at least quadrupled every decade since 1970. That figure is “a huge, huge underestimate… it’s the tip of the iceberg,” said ecologist Helen Roy, co-author of the UN Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) report. Without intervention to prevent their spread and impact, the total number of invasive species globally will be one-third higher in 2050 than it was in 2005. the scientists say.
科学家们说，全球经济成本是巨大的，自1970年以来，每十年至少翻两番。联合国政府间生物多样性和生态系统服务平台(IPBES)的合著者、生态学家海伦·罗伊(Helen Roy)表示，这个数字(经济成本)“被大大低估了……它只是冰山一角”。科学家们说，如果不采取干预措施防止它们的扩散和影响，到2050年，全球入侵物种的总数将比2005年增加三分之一。
Alien species are plants, animals or other organisms that have been moved through human activities to a new region or area. An alien species becomes invasive when it establishes itself in that new area and creates a negative impact on the local biodiversity and ecosystems, including on people’s way of life. Numerous examples include water hyacinths clogging up lakes and rivers in Africa, lion fish impacting local fisheries in the Caribbean and the Giant African land snail taking over villages on Christmas Island in the Indian Ocean.
外来物种是指通过人类活动转移到一个新地区或区域的动植物或其他生物。当一个外来物种在一个新地区扎根并对当地的生物多样性和生态系统，包括对人们生活方式产生负面影响时，它就成了入侵物种。许多例子其中包括风信子堵塞了非洲湖泊和河流，狮子鱼影响了加勒比地区当地的渔业，以及巨型非洲陆地蜗牛占领了印度洋圣诞岛上的村庄。
