A number of people, from William James to Dave Foreman and Vandana Shiva, have suggested that humans are at war with nature. Moreover, the analogy with warfare figures in at least one important argument for strategic monkeywrenching.

This paper argues that the analogy with warfare should not be used for justificatory or rhetorical purposes, but that (...) it may nevertheless have a legitimate heuristic role to play in environmental philosophy.
