Сводка	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.	The chain of explanation is the core analytical device of regional political ecology, introduced by Piers Blaikie and Harold Brookfield in Land Degradation and Society (1987). It treats an environmental outcome such as soil erosion not as a technical accident but as the visible end of a causal chain that runs from the individual land manager outward through the household, the regional economy, the state, and ultimately the world economy. Rather than blaming the farmer or the rainfall, the analyst follows the chain link by link to show how decisions on the ground are shaped by pressures and constraints set at much wider scales. The method is closely allied to Andrew Vayda's progressive contextualization, which begins with a specific human-environment activity and explains it by placing it in progressively wider contexts. Together these give political ecology a disciplined, scale-spanning way to connect local degradation to its political-economic roots.
