The countryside surrounds the city. Finance capital can only sustain itself as long as the base of the supply chain keeps producing the food and raw resources that they collect rent on, as well as the vast majority of labor power which sits in the periphery; environmental collapse threatens this process of extraction at its core. Capitalism will not necessarily be eradicated as an immediate consequence of environmental collapse but I think that it will need to go through some transformational change, akin to the grave acceleration of imperialism that happened in the 1970s but in the opposite direction.
