We are on a runaway train headed over the climate cliff as we stoke the engine with more coal to increase its speed. - John Bellamy Foster

Socialists have all too often failed to take ecological issues seriously enough. However, this is not a fault of socialists alone, as the fault applies even more to the liberal tradition taken as a whole. But whatever we choose to say about socialism in the twentieth century, it has to be emphasized that no one can be truly socialist and indeed Marxist in the twenty-first century and fail to acknowledge the full severity of the planetary ecological crisis. We are either at the forefront of the struggle to protect the earth as a place of human habitation (and as a home for innumerable species) or we are on the side of the system’s creative exterminism of the Earth system as we know it.

It has been long understood that “” is a myth. To make fundamental changes in the commodity economy it is necessary to have power over production.

Capitalism imposes its laws of motion on the environment, irrespective of the biogeochemical cycles of the planet and the earth’s metabolism, so that it creates rifts or ruptures in the biogeochemical cycles of the Earth system, disrupting ecosystem relations in ways that transcend the mere scale-effects of economic growth. It is this problem of the metabolic rift that is our deepest challenge. Sustainability is more and more compromised at ever higher levels—a continually accelerating threat to civilization and life itself.
