In this sequence I try to determine the most valuable aspects of nature, after observing that lots of people find it valuable. One of the major candidates is “ecosystem services,” a term describing benefits we get from nature.[1] I find that the total value of all ecosystem services is high, but the marginal unit wouldn't meaningfully diminish the benefits we receive. In this post I explore How valuable ecosystem services are (about $45 trillion per year) What those ecosystem services are (nutrient cycling, etc) How possible it is to get those same benefits from other sources besides nature And whether biodiversity is providing the instrumental gain we get from nature. A quick clarification: Biodiversity is a measure of how many distinct species exist in nature (although it ambiguously can refer to local density of species, total extant global species, diversity within a species, and/or variety of ecosystems). Biodiversity is not equivalent to ecosystem services - as I demonstrate in this post. Breakdown of Ecosystem Services The estimated dollar equivalents of [...] --- Outline: (00:19) What Has Nature Done For Me Lately?
