Derrick Jensen (born December 19, 1960) is an American author, ecophilosopher, radical environmentalist, and anti-civilization advocate. According to Democracy Now!, Jensen "has been called the poet-philosopher of the ecological movement."As well as presenting a love letter to the natural world, Jensen's writing critiques the effects and concept of civilization, exploring what he describes as its inherent values, hidden premises, and modern links to supremacism, oppression, and genocide, as well as to corporate, domestic, and worldwide ecological abuse. He has consistently called for the guerrilla destruction of civilization and of Western culture, which he views as inherently unsustainable and as an inevitable cause of ecocide.
