據(jù)報告稱，自 1970 年來全球野生動物總數(shù)已減少 58% 。由倫敦動物學會（ Zoological Society of London ）和世界自然基金會（ WWF ）共同編寫的“地球生命力”評估報告表明，如果該趨勢持續(xù)下去，到 2020年 為止脊椎動物數(shù)量將會下降三分之二。相關(guān)數(shù)據(jù)顯示，居住在湖泊、河流、濕地的動物正經(jīng)受最大的威脅。請聽 Rebecca Morelle 的 報道。
Looking at data collected on 3,700 different species of birds, fish, mammals, amphibians and reptiles, the researchers analysed how population sizes have changed over time.
They believe that since 1970, species have declined by an average of 58%. Some have fared very badly, such as African elephants, whose numbers have been cut by a third in the last decade, and the Amur leopard, which is as few as 70 animals left in the world.
The report says that human activity is to blame and concludes that if nothing is done, wildlife populations could fall by 67% from 1970 levels by the end of the decade.
