Foucault and the Environment?

Just wondering if anyone out there in the rather silent Foucault land knew 
of any discussion of a Foucauldian approach to the environment.  How about, 
maybe a discussion of Nietzsche's writing on nature?  I'm trying to think 
how power/knowledge might specifically operate in environmental discourse.  
I can understand how present environmental discourse might serve as a 
quasi-scientific body of knowledge, but I'm wondering what space of 
resistance exists for an environmental crisis which seems to be seen as 
largely a by-product of capitalism and the fetishism of consumption.  In 
other words,  I need help understanding how Foucault's analysis of power in 
discursive formations can be utilized to understand environmental 
destruction AND to orient people towards some alternative.
