Marx and the Earth is a detailed and vigorous defence and reassertion of the classical Marxist position in regards to Marx's Ecology.
I've been asked to review this for another publication and I'll post a link here when this has been published.
In the meantime feel free to have a look at some reviews I've written of other books by these authors.
