Book excerpt: Radical environmental groups throughout the world, militantly committed to defending the ecology, are growing in size and influence. In this country, activists engage in ecological civil disobedience and "ecotage"-- the sabotaging of equipment to prevent ecological damage-- in the struggle to preserve wilderness lands. These ecoteurs have gone beyond traditional conservation concerns to a new philosophy-- Deep Ecology, or biocentrism-- that calls into question not only the wisdom, but the legitimacy of humanity's domination of nature. In "Green Rage", Christopher Manes has written a brilliant defense of radical environmentalism, challenging the ethics of modern industrial society and asserting the right of the natural world to blossom, evolve, and exist for its own sake.
