Actually, the Louis Harvey referred to above is me. One issues is whether the Nazis were "radical ecologists". Harvey says yes and I say no. Closely related to this issue is whether the American Indian had more ecological awareness than the capitalist class. Harvey says they don't. I say they do.
I have been writing about red-green issues for over four years now and my articles can be found at:

I consider myself very close to John Bellamy Foster politically. I should also mention that Paul Burkett has been working on a comprehensive analysis of the ecological implications of Marx's thought that will be published by St. Martin's Press this year.
