I argue that James Sterba's recent attempt to show that, despite their
foundational axiological differences regarding the relative value of
humans and members of nonhuman species, anthropocentrists and nonanthr
opocentrists would accept the exact same principles of environmental j
ustice fails. The failure to reconcile the two positions is a product
of an underestimation of the divergence that occurs at the level of ge
neral principles and practical policy as a result of the initial value
commitments which characterise each position. The upshot of this is t
hat, contrary to those who argue that environmental ethicists ought to
move beyond the traditional anthropocentric-nonanthropocentric debate
, the foundational debate about interspecific egalitarianism will cont
inue to issue in substantial debates about environmental policy format
ion.
