We are astonishingly ignorant about how many species are alive on earth today, and even more ignorant about how many we can lose yet still maintain ecosystem services that humanity ultimately depends upon. Mora et al.'s paper is important in offering an imaginative new approach to assessing total species numbers, both on land and in the sea.
我们对当今地球上有多少物种知之甚少,更不知道我们可以失去多少物种,而仍能维持人类最终赖以生存的生态系统服务。莫拉等人的论文很重要,它提供了一种富有想象力的新方法来评估陆地和海洋中物种的总数。
