生态系统的服务和产生这些服务的自然资本存量对地球生命维持系统的运作至关重要。它们直接或间接为人类提供了利益，并因而成为这个星球整个经济价值的一部分。根据已发表的研究和一些原始计算，我们估计了16个生物群落的17种生态系统服务的当前经济价值。就整个生物圈而言，其价值（大部分在市场之外）估计在每年16 -54万亿美元（10（12））之间，平均每年33万亿美元。由于不确定性的性质，必须将其视为最小估计值。全球国民生产总值每年约为18万亿美元。
The services of ecological systems and the natural capital stocks that produce them are critical to the functioning of the Earth's life-support system. They contribute to human welfare, both directly and indirectly, and therefore represent part of the total economic value of the planet. We have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations. For the entire biosphere, the value (most of which is outside the market) is estimated to be in the range of US$16-54 trillion (10(12)) per year, with an average of US$33 trillion per year. Because of the nature of the uncertainties, this must be considered a minimum estimate. Global gross national product total is around US$18 trillion per year.
