Capitalism is burning the planet like anti-globalization movements have been warning for decades. In the 21st century, the contradiction between capital and nature is recomprising the conflict between labor and capital which defined the 20th century. Thus the ecological question is determining the social question and the collective survival of the human species in a fast-collapsing biosphere, marked by the large extinctions of the Anthropocene. Radical ideology on the environment arguably comes in three major strands that have emerged since the 1980s and 1990s. The first is defined by Murray Bookchin and the confederalist, bioregionalist, and ecofeminist experiment of Rojava. In can also be defined as libertarian socialist and eco-municipalist. It has a strong influence on Ecologia Politica and other similar networks of European climate collectives. The second is eco-marxism as it emerges most strongly in the widely read works of Andreas Malm and Kohei Saito. Their roots are in the journals Capitalism, Nature, Socialism and especially the Monthly Review and the work of Bellamy Foster and others on the metabolic rift in Das Kapital. A different, world-systems Wallersteinian strand is that of Jason Moore and his concept of the Capitalocene (which Saito opposes in in his Japanese bestseller, Capital/Marx in the Anthropocene). The work of Malm, who also argues in favor of the capitalocene in his treatment of fossil capital, is inspired by and inspires Ende Gelaende and other autonomist climate movements. The third strand is arguably the oldest because it goes back to Edward Abbey and monkeywrenching (1975) and the origins of Earth First! (1980), as well as the actions of the Earth Liberation Front after Seattle. In North America it is anarchist in inspiration and outlook (and transfeminist and deep-ecologist, e.g. Defend Atlanta Forest), while in Europe it is antagonist and autonomist in nature, in a powerful syncretic synthesis of radical ecology and queer ideology that we can term Zadism, after its most relevant and symbolic manifestation, la ZAD, an ecological autonomous zone defended by black blocs and intersectional alliances with farmers and environmental groups, such those seen in Soulèvements de la Terre at Sainte-Soline. What are the intellectual and historical elements that can be employed to arrive at a synthesis on revolutionary ideological strategy for ecological anticapitalism? The objective is coin ideas and slogans, and debate forms of organization and communication that can push forward the world’s climate justice movements until destruction and overthrow of fossil capitalism and its stranglehold on human societies and natural environments.
