摘要

Of all the species that have populated Earth at some time over the past 3.5-billion years, more than 95% have vanished - many of them in spectacular die-offs called mass extinctions. On that much, researchers can generally agree. Yet when it comes to taking stock of how much life exists today - and how quickly it will vanish in the future - uncertainty prevails. Studies that try to tally the number of species of animals, plants and fungi alive right now produce estimates that swing from less than 2 million to more than 50 million. The problem is that researchers have so far sampled only a sliver of Earths biodiversity, and most of the unknown groups inhabit small regions of the world, often in habitats that are rapidly being destroyed.%过去40亿年某些时候地球上曾经存在过的物种90%以上都已经消失了，其中很多是在大规模灭绝中消失的。这让人们将目光聚焦于那些仍然存在的物种以及它们存活的机会有多大。在本期Nature的一篇News Feature文章中，我们试图对地球上仍然存在的生命进行盘点（结果证明这并不是一件简单的事情），同时提出一个问题：我们需要采取什么样的保护措施来停止生物多样性的消耗性丧失？封面：圭亚那帕卡赖马山的濒危黑眼树蛙（Agalychnis moreletii) (Joe Riis/National Geographic Society/Corbis)。
