A2: Utilitarian Well-Being

De-extinction should be judged by its expected effects on overall pleasure, suffering, and well-being.

1. Restored grazing ecosystems protect permafrost carbon AND sequester more---net climate gain. Pleistocene Park d. [Pleistocene Park, n.d., “Scientific Background”, Pleistocene Park, https://pleistocenepark.ru/science/]

Mann 18 [Paul Mann, Senior Lecturer, Geography and Environmental Sciences, Northumbria University, Newcastle, 2018, “Could Resurrecting The Mammoth Help Stop Arctic Emissions?”, ScienceAlert, https://www.sciencealert.com/could-resurrecting-mammoths-help-stop-arctic-emissions]
3. Mammoth-like herbivores can restore the degraded Arctic steppe and cool permafrost.

4. No established method compares welfare across individuals or species---the calculus is underdetermined. Browning 23 [Heather Browning, 2023, “Welfare comparisons within and across species”, Springer Nature, https://researchonline.lse.ac.uk/id/eprint/117584]
5. No agreed method compares welfare levels across species---expected-harm claims are speculative.

11. Hedonic states adapt to circumstances---subjective well-being measures can't ground impartial judgment. Kahneman 06 [Kahneman, 2006, “Would You Be Happier If You Were Richer? Measurement of subjective well-being”, Journal of Economic Perspectives, https://inequality.stanford.edu/sites/default/files/media/_media/pdf/Reference Media/Kahneman_2006_Measurement.pdf]

14. Consequentialism gives no concrete answers---virtue ethics judges acts by character, not outcomes. Weltman 22 [Daniel Weltman, associate professor of philosophy at Ashoka University, India, 2022, “G. E. M. Anscombe's "Modern Moral Philosophy"”, 1000-Word Philosophy: An Introductory Anthology, https://1000wordphilosophy.com/2022/05/20/anscombe/]
