Abstract

The article considers how the preservation of biodiversity is morally justified in some of the key texts on environmental ethics, i.e. whether or not biodiversity can be justified as a moral end in itself. The views are classified according to the criteria which they hold to be the ultimate moral beneficiaries; positions are named as anthropocentrism, biocentrism and ecocentrism. In general, they are not in favor of regarding biodiversity as intrinsically valuable, but think its moral value as derivative. This means that the myriad characters of life on Earth are to be maintained as diverse because of their instrumental value for the constituents. It seems that Naess's deep ecology is the only major position that argues for biodiversity's intrinsic value, but this view has proved to be problematic.
