Despite some important successes, the efforts of the environmental movement have thus far failed to activate the kinds of personal and social changes necessary to meet the many ecological challenges we face. A growing body of psychological research suggests that if these efforts incorporated more knowledge about human identity (including our values, our sense of social identity, and the ways we cope when threatened), greater progress towards a more sustainable (and socially just) world might be forthcoming.
