Anarchist Environment texts?

One of my co-workers, who knows my politics, approached me about environmentalism today. He's a left-liberal, but is familiar with socialism and anarchism. I also know his mum and she's a workplace militant. Anyway, I gave him a pretty standard response about not being able to separate environmental politics from class politics and using our power as workers to change industry practices; mentioning the Australian green bans as an example. He was quite receptive, but mentioned green capitalism and entering an industry as a capitalist with the explicit goal of changing it. Once again, "greenwashing", iron law of the market, profit being fundamentally in conflict with any ideals. The conversation ended there as we ran out of time, but I think I'd really like to give him a good short text to read (he's read education stuff from libcom that I've sent him previously).

Basically, I'm looking for a good introductory text that outlines a class approach to environmental, critiques green capitalism (ideally a good Marxist approach to this), and outlines out environmental questions would be dealt with in an anarchist society. Any suggestions?
