Since the 1980 formation of Earth First!, radical environmental movements have proliferated widely. Their adversaries, law enforcement authorities and some scholars accuse them of violence and terrorism. Here, I scrutinize such charges by examining 18 years of radical environmentalism for evidence of violence and for indications of violent tendencies. I argue that despite the frequent use of revolutionary and martial rhetoric by participants in these movements, they have not, as yet, intended to inflict great bodily harm or death. Moreover, there are many worldview elements internal to these movements, as well as social dynamics external to them, that reduce the likelihood that movement activists will attempt to kill or maim as a political strategy. Labels such as ‘violent’ or ‘terrorist’ are not currently apt blanket descriptors for these movements. Thus, greater interpretive caution is needed when discussing the strategies, tactics, and impacts of radical environmentalism.
