The authors estimated the 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 between $16 and 54 trillion/year (1997 U.S. dollars), with an average of $33 trillion/year. Because of the nature of the uncertainties, this must be considered a minimum estimate.
