This article considers whether any interpretation of the idea of equal claims to the natural world can resolve the Canyon Dilemma (i.e. can justify protecting the Grand Canyon but not a small canyon from mining by a poor generation). It first considers and ultimately rejects the idea of subjecting natural resource rights to an intergenerational equal division. It then demonstrates that a pluralist theory of environmental justice committed to both respect for the separateness of persons and to the collective good (...) can justify a type of intergenerational non-absolute equal division of natural resource rights that can navigate the Canyon Dilemma.
