“Cost-effectiveness accounting for soil nematodes, mites, and springtails” by Vasco Grilo🔸

I am looking for work, and welcome suggestions for posts.Summary I think the impact of the vast majority of interventions is driven by effects on wild animals. In particular, by effects from land use change on soil nematodes, mites, and springtails, which are the most abundant terrestrial animals. There are 4.4*10^20 top soil nematodes, and 10^19 soil arthropods, “≈95% of which are soil mites and springtails”. I estimate random soil nematodes, mites, and springtails have (expected) welfare ranges (as fractions of that of humans) of 6.47*10^-6, 3.57*10^-5, and 6.17*10^-5, which are 0.324 %, 1.79 %, and 3.09 % of Rethink Priorities’ (RP's) median welfare range of silkworms. I calculate soil nematodes, mites, and springtails have (in expectation) a welfare of -4.36*10^-6, -1.57*10^-5, and -2.35*10^-5 QALY/animal-year, and an annual welfare of -296 k, -13.9 k, and -10.4 k times that of humans. The annual welfare of soil nematodes being 12.6 times that of soil [...] ---Outline:(00:16) Summary(06:47) Introduction(10:57) Welfare ranges(16:50) Welfare per animal-year, and annual welfare(22:24) Welfare per area(25:08) Cost-effectiveness(40:02) Effects on soil animals cannot be neglected just because they are uncertain(43:03) Acknowledgements--- First published: June 3rd, 2025 Source: https://forum.effectivealtruism.org/posts/Rjutj7Jd2v2KHvDyA/cost-effectiveness-accounting-for-soil-nematodes-mites-and --- Narrated by TYPE III AUDIO. ---Images from the article:Apple Podcasts and Spotify do not show images in the episode description.
