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: The concept of ecosystem services has become an important model for linking the functioning of ecosystems to human welfare Understanding this link is critical for a wide-range of decision-making contexts.

TL;DR: In this article, the economics of pollution and optimal depletion rates for natural resources are discussed, and a comprehensive and popular textbook for undergraduate students of environmental economics is presented. The book deals fully with the orthodox theorems of the economics, and also appeals to geographers and environmentalists.

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: A review of the literature on environmental valuation of ecosystem services across the range of global biomes can be found in this article, where the main objective is to assess the policy relevance of the information encompassed by the wide range of valuation studies that have been undertaken so far.
