We study fairness in economies where humans consume one private good and one public good representing the welfare of other species. We show that a social evaluator cannot be egalitarian with respect to humans while always respecting humans’ unanimous preferences. One solution is to respect unanimous preferences only when doing so does not lead to a decrease in the welfare of other species. Social preferences satisfying these properties reveal surprising connections between concerns for other species, egalitarianism among humans, and unanimity: the latter two imply a form of dictatorship from humans with the strongest preference for the welfare of other species.
