Ecosystem health, as James Nelson argues, must be understood as having both descriptive and normative content; it is in this sense a 'morally thick' concept. The health analogy refers (a) at the similarities between conservation ecology and medicine or plant pathology as normative sciences,
and (b) to the ability of ecosystems to 'heal' themselves in the face of disturbances. Nelson, however, goes beyond these two aspects and argues that judgements of illness in ecosystems only support moral obligations to protect them if they are attributed a 'good of their own'. But this latter
extension of the analogy flies in the face of ecological science, which has been forced to abandon organicism. If one separates the question of the warranted assertibility of environmentalists' goals from the question of where values in nature are located, the search for an objective realm
of value realism can be seen to be unnecessary.
Environmental Values is an international peer-reviewed journal that brings together contributions from philosophy, economics, politics, sociology, geography, anthropology, ecology and other disciplines, which relate to the present and future environment of human beings and other species. In doing so we aim to clarify the relationship between practical policy issues and more fundamental underlying principles or assumptions.
Environmental Values has an impact factor (2013) of 1.739.
