Ecosocialism is a radical social theory and variant of red-green politics. It documents the connections between the dynamics of capitalist relations and their destructive effects on the biosphere, including human life. Given the ecosocialist commitment to Marxian analysis, it is also dubbed ecological Marxism. Ecosocialism is constructed through a series of critiques: critique of “green” economics, liberal environmentalism, and other “within-the-system” remedies to ecological degradation; critique of deep ecology and bioregionalism; critique of classical socialist politics and of “actually existing socialisms” etc. (see, e.g., Kovel 2007). But it is capitalism―in its multiple, interwoven expressions―that is the ecosocialist’s primary focus and starting point of conceptualization and praxis.
