Ecosocialists are to some extent divided on whether Marx was an Ecosocialist or not, some seeing him as mainly a ‘productivist’. Indeed, Ecosocialism is probably closer to Anarchism than mainsteam twentieth century socialisms. Certainly Marx has a big influence on Ecosocialism, but that was true of Bookchin as well. Personally, I tend to agree with Bookchin, but I am agnostic on the matter anyway, I don’t think it matters much whether Marx was Green, for example. We take from him his thoughts on capitalism and socialism and use them for our age.
Like Marx, Bookchin’s work now looks dated. I think scarcity will be back quite soon, as natural resources deplete and climate change makes land scarce and drinking water in all probability too. I don't share his faith in technology to save us, either. But I do take his point, the world has moved on from the nineteenth century when Marx was developing his ideas for a post capitalist socialist world.
