One of the main contributions that link up global capitalist expansion and the impact on the environment was made by James Oв??Connor. He argues that as a result of the second contradiction of capitalism, there are devastating environmental consequences, but also impacts threatening the viability of capitalist firms, if not capitalism itself. He has argued that this contradiction is tied to the growth of environmental movements, which can come to challenge the sustainability of the capitalist system.
In addition to a discussion of OВґConnorВґs original contribution, the importance of environmental activism in struggles related to large-scale mining, hydroelectric dams, and climate change is presented. A stimulating ecosocialist contribution on solar communism and fossil fuel dependence is also presented in light of OВґConnorВґs work and the debate over climate change.
