It has been argued by some that an environmental ethic is possible only if meta-ethical objectivism is true. However, there are good reasons for thinking that it is not true. This entails that either an environmental ethic is not possible or that it is compatible with a non-objectivist meta-ethic. The second disjunct is true. A subjectivist meta-ethic is outlined and is shown to provide conceptual space for the claims of an environmental ethic.
