I am no ecological Pollyana. I have borne, and will continue to bear, feelings of wholehearted melancholy over the ecological state of the earth. How could I not? How could anyone not? But I am unwilling to become a hand-wringing nihilist, as some environmental 'realists' seem to believe is the more mature posture. Instead, I choose to dwell, as Emily Dickinson famously suggested, in , where we cannot predict what will happen but we make space for it, whatever it is, and realize that our participation has value. This is grown-up optimism, where our bondedness with the rest of creation, a sense of profound interaction, and a belief in our shared ingenuity give meaning to our lives and actions on behalf of the more-than-human world.
