Term invented by future Environmental Action members at Earth Day, 1970, to describe the sabotage of environmentally harmful machineries (bulldozers, SUVs) and projects (housing tracts, supermalls). Similar to monkeywrenching (Edward Abbey’s term from his 1976 novel The Monkey Wrench Gang). Most greens consider ecotage inappropriate until, at the very least, actions like nonviolent resistance have proven futile. Dave Foreman of EarthFirst! distinguishes between terrorism (which is aimed at innocent people) and ecotage (aimed at devices that ruins ecosystems). Farmer-writer Gene Logsdon has wondered whether groups who resort to such acts ever think about protecting, say, vanishing topsoil.
