From Wikipedia:
Derrick Jensen (born December 19, 1960) is an American author and environmental activist who lives in Northern California. He has published several books questioning contemporary society and its values, including A Language Older Than Words, The Culture of Make Believe, and Endgame. He holds a B.S. in Mineral Engineering Physics from the Colorado School of Mines and an M.F.A. in Creative Writing from Eastern Washington University. He has also taught creative writing at Pelican Bay State Prison and Eastern Washington University.
Jensen is often labeled an anarcho-primitivist, by which is meant he believes that civilization is inherently unsustainable and based on violence. He argues that the modern industrial economy is fundamentally at odds with healthy relationships, the natural environment, and indigenous peoples. Jensen’s work catalogues… the pervasiveness of abuse, hatred, rape, environmental destruction, and dishonesty (which… serve to maintain the systemic abuse of civilization). He concludes that the very pervasiveness of these behaviors indicates that they are diagnostic symptoms of the greater problem of civilization itself. Accordingly, he exhorts readers and audiences to help bring an end to industrial civilization.
