Nonanthropocentric climate ethics

Abstract Anthropogenic climate change poses increasingly severe long‐term threats to living things worldwide. It may even contribute to a mass extinction that would leave biodiversity depleted for millions of years—quite possibly longer than the duration of the human species. Such effects are obviously of ethical concern, but because traditional ethical theories have focused on the relatively short‐term interests of human beings, they offer little guidance. In the late 20th century, a growing number of ethical activists and theorists sought to expand moral consideration to nonhuman animals and to the diverse life forms and habitats of wild nature. Simultaneously and at first independently, others began to develop long‐term (sometimes called “intergenerational”) ethics, which extends moral consideration into the distant future. Concerns about future climate change quickly became a central focus of this work. But only in this century have there been concerted efforts to integrate these lines of thought into far‐sighted nonanthropocentric climate ethics. These efforts are the subject of this review.
