As a bare minimum, environmental ethics comprises two fundamentally divergent concerns—namely, concern with individual nonhuman animals as direct objects of moral concern and concern with species, ecosystems, environments, wilderness areas, forests, the biosphere, and other nonsentient natural or even abstract objects as direct objects of moral concern. Thus, even a cursory examination of some major environmental issues affecting the nonsentient environment indicates that those problems are insoluble outside of the context of international justice. An environmental ethics is inseparable from a system of international justice, not only in terms of policing global dangers and verifying and monitoring compliance with international agreements, but also in terms of implementing the distributive justice necessary to prevent poor countries from looking only at short-term gains. The relevance of a viable mechanism of international justice to environmental ethical concerns is manifest.
