The celebration of the 30th anniversary of The Trumpeter is a good time to take another look atthe deep ecology movement and its development. A so-called “new conservation” movement has recently emerged that claims the traditional conservation/environmental movement (and deep ecology) had it all wrong. I will offer an informal summary of the deep ecology movement, while referencing more detailed analyses of the issues. Finally I will refer to a powerful new critique of the “new conservation” movement, inspired by the leading conservation biologist Michael Soulé: Keeping the Wild: Against the Domestication of Earth.
