I define ecosabotage and relate this definition to several well-known analyses of civil disobedience. I show that ecosabotage cannot be reduced to a form of civil disobedience unless the definition of civil disobedience is expanded. I suggest that ecosabotage and civil disobedience are special cases of the more general concept of conscientious wrongdoing. Although ecosabotage cannot be considered a form of civil disobedience on the basis of the standard analysis of this concept, the civil disobedience literature can provide important insights (...) into the justification of ecosabotage. First, traditional appeals to a higher law in justifying ecosabotage are no more successful than they are in justifying civil disobedience. Second, utilitarian justifications of ecosabotage are promising. At present there is no apriori reason tosuppose that some acts of ecosabotage could not be justified on utilitarian grounds, although such ecosaboteurs as Dave Foreman have not provided a full justification of its use in concrete cases.
