La collapsologie est un courant de pensée transdisciplinaire apparu dans les années 2010 qui envisage les risques d’un effondrement de la civilisation industrielle et ses conséquences.
En France, l’étude d’un possible effondrement de la civilisation « thermo-industrielle » est initiée par l’Institut Momentum co-fondé par Yves Cochet et Agnès Sinaï. Ces derniers définissent l’effondrement comme « le processus irréversible à l’issue duquel les besoins de base (eau, alimentation, logement, habillement, énergie, etc.) ne sont plus fournis (à un coût raisonnable) à une majorité de la population par des services encadrés par la loi».
Potential external cost savings associated with the reduction of animal-sourced foods remain poorly understood. Here we combine life cycle assessment principles and monetarization factors to estimate the monetary worth of damage to human health and ecosystems caused by the environmental impacts of food production. We find that, globally, approximately US$2 of production-related external costs were embedded in every dollar of food expenditure in 2018—corresponding to US$14.0 trillion of externalities. A dietary shift away from animal-sourced foods could greatly reduce these ‘hidden’ costs, saving up to US$7.3 trillion worth of production-related health burden and ecosystem degradation while curbing carbon emissions. By comparing the health effects of dietary change from the consumption versus the production of food, we also show that omitting the latter means underestimating the benefits of more plant-based diets. Our analysis reveals the substantial potential of dietary change, particularly in high and upper-
