Ecotage! was a 1972 paperback book edited by Sam Love and David Obst and published by Pocket Books.

The book was a collection of ideas that had been solicited by the group Environmental Action over the previous year in preparation for the publication of the book, for using sabotage, attention-grabbing stunts, and other ideas to draw attention to environmental issues. “Ecotage” is a contraction of ecological (or economic) and sabotage. The cover of Ecotage! features a photograph of a hippie throwing a pie in the face of a business executive.

The book is credited as one of the early inspirations for radical environmental activism, along with similar works such as Edward Abbey’s 1975 novel The Monkey Wrench Gang. (wikipedia)
