Ecological economics (EE) provides us with a critical lens for examining both the decline of ecospheric health and the philosophical and political pathologies of mainstream economics. In this essay, I set out the main and distinctive tenets of EE and then draw out their democratic and anti-capitalist tendencies. For example, EE asks a question that no environmental economist would ever consider. This is the scale question, or “How large can a planetary economy be?” Acknowledging economic limits is a heretical turn within mainstream economics, but many proponents of EE fail to see the question of scale as a political question. That is, EE remains wedded to the idea that economics and politics are separable. Green abolitionism can draw from the empirical work of EE and posit a political economic alternative.
