随着第17届生物多样性大会（Cop17）开幕，自1921年以来的记录显示，除了阿尔卑斯地区外，欧洲各地减少的蜂物种多于增加的物种。
研究发现，欧洲大多数野生蜂物种及其约一半的食虫蝇物种在过去一个世纪中出现减少，这一发现正值联合国生物多样性峰会在亚美尼亚开始之际。
As Cop17 kicks off, records since 1921 show more bee species declining than increasing in all parts of Europe except the Alps Most of Europe’s wild bee species and about half of its hover fly species have declined over the last century, a study has found, as a UN biodiversity summit begins in Armenia.
自1921年以来的记录显示，除了阿尔卑斯地区外，欧洲各地减少的蜂物种多于增加的物种。研究发现，大西洋地区和大陆地区的蜂及食虫蝇物种丰富度持续下降，尽管其他地区的趋势呈混合甚至积极态势。
Records since 1921 show more bee species are declining than increasing in all parts of Europe except the Alpine region. The richness of bee and hover fly species suffered a persistent drop in the Atlantic and Continental regions, the study found, though trends in other regions were mixed or even positive.
