Abstract The paper reviews and outlines criteria that have been suggested for determining whether or not to save a species for extinction. Priorities as set out in the World Conservation Strategy, cost-benefit analysis, and the safe minimum standard approach are given particular consideration. The different criteria also are compared assuming that there is an absolute upper constraint on the amount of resources available for the conservation of species. There is some discussion of whether the reduction in available crop varieties is adding to or reducing the instability of crop yields. It is claimed that relative variability appears to be falling but there may be an increasing risk of non-sustainability. The importance of the burden of proof in the conservation versus non-conservation debate is stressed and it is suggested that recent economic thought has swung more towards the view that the burden of proof should rest on those seeking to carry out activities which may extinguish a species.
