TL;DR: In this paper, the authors provided an updated estimate based on updated unit ecosystem service values and land use change estimates between 1997 and 2011, using the same methods as in the 1997 paper but with updated data, the estimate for the total global ecosystem services in 2011 is $125 trillion/yr (assuming updated unit values and changes to biome areas).

TL;DR: This paper provided a crude initial estimate of the value of ecosystem services to the economy using data from previous published studies and a few original calculations, and estimated the current economic value of 17 ecosystem services for 16 biomes.

TL;DR: In this paper, the authors trace the history leading up to these publications and the subsequent debates, research, institutions, policies, on-the-ground actions, and controversies they triggered.

TL;DR: It is estimated that the overall benefit:cost ratio of an effective global program for the conservation of remaining wild nature is at least 100:1.

TL;DR: The concept of ecosystem service value can be a useful guide when distinguishing and measuring where trade-offs between society and the rest of nature are possible and where they can be made to enhance human welfare in a sustainable manner.
