I’ve spent almost three decades advocating for care of the Earth, and while in some ways my understanding of the various issues has become much more nuanced in the most important ways, it has become much simpler. My ethic is as simple as this: if we cease and desist from making our planet uninhabitable for us and many other species, if we finally choose to tend this creation with skill and care, it will be because we are moved by the world’s beauty, awed by its complex interrelatedness, and feel ourselves kin with the rest of creation. Put simply, because we experience a great love for the world. What we love is what moves our heart, and what moves our heart is what moves our lives.
