The “£140m per salmon” framing commits a category error. it treats a program aimed at maintaining a viable population as a consumer purchase of discrete animals. The state is not buying fish; it is trying to stay on the safe side of nonlinear, potentially irreversible thresholds, eg stock collapse, genetic erosion, loss of a keystone species. The relevant unit is not an individual salmon but the persistence of a functioning salmon-bearing river over decades.

The opportunity-cost comparison is incomplete because the largest costs of species decline are unpriced and therefore invisible to cost-benefit analysis.

Zvi is so often inscrutable to those who don't follow super carefully. What is "3" referencing?
