2002年，世界各国领导人通过《生物多样性公约》承诺到2010年大幅降低生物多样性丧失的速度。我们编制了31项指标来报告实现这一目标的进展情况。大多数生物多样性状况指标（涵盖物种种群趋势、灭绝风险、栖息地范围和状况以及群落组成）都显示下降，近期速度没有显著降低，而生物多样性所受压力的指标（包括资源消耗、外来入侵物种、氮污染、过度开发和气候变化影响）则显示上升。尽管在一些地方取得了成功，应对措施也在增加（包括保护区的范围和生物多样性覆盖范围、可持续森林管理、对外来入侵物种的政策应对以及与生物多样性相关的援助），但生物多样性丧失的速度似乎并没有减缓。
In 2002, world leaders committed, through the Convention on Biological Diversity, to achieve a significant reduction in the rate of biodiversity loss by 2010. We compiled 31 indicators to report on progress toward this target. Most indicators of the state of biodiversity (covering species' population trends, extinction risk, habitat extent and condition, and community composition) showed declines, with no significant recent reductions in rate, whereas indicators of pressures on biodiversity (including resource consumption, invasive alien species, nitrogen pollution, overexploitation, and climate change impacts) showed increases. Despite some local successes and increasing responses (including extent and biodiversity coverage of protected areas, sustainable forest management, policy responses to invasive alien species, and biodiversity-related aid), the rate of biodiversity loss does not appear to be slowing.
