“All environmentalists should be activists, but activism can take a variety of forms. The way that environmental philosophers can be the most effective environmental activists is by doing environmental philosophy. Of course, not everyone can be or wants or needs to be an environmental philosopher. Those who are not can undertake direct environmental action in other ways. My point is that environmental philosophers should not feel compelled to stop thinking, talking, and writing about environmental ethics, and go do something about it instead—because talk is cheap and action is dear. In thinking, talking, and writing about environmental ethics, environmental philosophers already have their shoulders to the wheel, helping to reconfigure the prevailing cultural worldview and thus helping to push general practice in the direction of environmental responsibility.”
