Eco-socialism or Green socialism is an ideology merging aspects of Marxism, socialism, Green politics, ecology and the anti-globalization movement. Eco-socialists generally believe that the expansion of the capitalist system is the cause of social exclusion, poverty and environmental degradation through globalization and imperialism, under the supervision of repressive states and transstatal structures; they advocate the non-violent dismantling of capitalism and the state, focusing on collective ownership of the means of production by freely associated producers and restoration of the Commons.
