The Dasgupta Review is the latest attempt at justifying financialisation of Nature, but also much more. It represents a high point in applying concepts of capital and wealth accumulation comprehensively to all aspects of human and non-human existence. Unravelling the flaws in the arguments, contradictions and underlying motives requires both understanding of and cutting through the specialist language, neoclassical economic models, mathematics and rhetoric. We offer a critical guide to and deconstruction of Dasgupta’s biodiversity economics and reveal its real aim. Framing critical biodiversity loss as an issue of asset management and population size is a blind to avoid questioning economic growth, which remains unchallenged and depoliticized despite apparently recognizing natural limits. Dasgupta ignores long-standing problems with capital theory and social cost-benefit analysis. Rather than a scientific review of biodiversity economics he offers impossible to achieve valuation, based on old flawed theories and methods, embedded in an unsavoury political economy.
