 Scanlon offers two solutions. The first is to limit the scope of his account. Contractualism is not an account of the whole of morality, but only an account of the morality of what we owe to other persons. This leaves open the possibility that our obligations to animals fall outside this part of morality. Scanlon also explicitly puts aside any moral obligations we might have in regard to the natural environment (Scanlon 1998, p. 179).
