 Hillel Steiner (2005) argues that all individuals are equally entitled to benefit from the exploitation of natural resources; as such, those left behind by territorial expropriation have the right to compensation, through the creation of a proposed Global Fund. Mathias Risse (2012) has more recently argued in favor of common ownership of the world’s natural resources as an independent ground of justice. Risse’s view is complex and polycentric, and includes sites on which global justice might be evaluated—including common humanity, shared subjection to a coercive legal system, and the fact that humanity shares a limited set of territorial goods. It is this latter aspect that is most relevant for our present discussion; Risse argues that the world’s natural resources, since they are not the result of any individual person’s agency, must be regarded as subject to symmetrical claims from all human persons. This vision of the world as given to mankind in common, of course, is borrowed from early modern thinkers; Risse vindicates their concern with natural resources, and argues that conclusions for both migration and for distributive justice can be derived from this ground.
