Environmental problems are a legion, and of radically differing kinds. Yet the notion of a unified environmental crisis persists. Such unification has a solid basis, firstly because all areas of the world are interwoven into a global system of extraction, production, trade and consumption. Secondly, diverse environmental problems interact in many ways. However, too often this slips into problematic totalization, ignoring the important local socio-ecological specificities. The search for environmental master metrics, the attempt to find common units of measurement for (...) diverse environmental impacts, is a consequential example of this. A path must be found between problematic master metrics that lack contextual understanding and can lead to perverse outcomes, and addressing environmental problems in a piecemeal fashion that overlooks a systemic view. One set of tools can never suffice when we are dealing with the complex and multifarious field of environmental issues. (shrink)
