Resumo	Metabolic rift analysis is a Marxian framework in environmental sociology that diagnoses the rupture in the material exchange, or metabolism, between human society and the rest of nature under capitalism. John Bellamy Foster's 1999 American Journal of Sociology article recovered the concept from Karl Marx, who drew on the soil chemist Justus von Liebig to describe how nineteenth-century industrial agriculture broke the nutrient cycle by shipping food and fiber from countryside to city and never returning the soil's elements. Foster argued that this 'irreparable rift in the interdependent process of social metabolism' is a classical foundation for environmental sociology rather than a modern afterthought. In The Ecological Rift (2010), Foster, Clark, and York generalized the idea to the full range of planetary boundaries, showing how the same logic of accumulation that splits town from country also displaces ecological damage across space and time. The analysis treats environmental degradation not as an accident but as a structural consequence of how production is organized for profit. It is a qualitative, historical-materialist pipeline that links political economy to biophysical flows.	Treadmill of production analysis is a political-economy framework that explains environmental degradation as the structural outcome of capitalism's built-in imperative to expand production and accumulate capital. Allan Schnaiberg introduced it in his 1980 book The Environment: From Surplus to Scarcity, arguing that competitive markets compel firms to reinvest profits in ever more capital-intensive and energy-intensive production, generating accelerating ecological withdrawals of resources and additions of pollution. The metaphor of a treadmill captures the way the system must keep running, expanding output, just to stay in place, so that environmental harm is not an accident but a systemic requirement. Crucially, Schnaiberg saw labor and the state as drawn into the same growth logic, since workers depend on the jobs growth provides and governments depend on the revenue and legitimacy it generates, forming a coalition that perpetuates the treadmill. Gould, Pellow, and Schnaiberg's 2004 article restated and defended the theory, clarifying its structure, its focus on production over consumption, and its evolution under globalization. The framework remains a cornerstone of critical environmental sociology and a counterpoint to ecological-modernization optimism.
