In his recent commentary on my work, entitled ‘Mazor on indirect obligations to conserve natural resources for future generations’ (Sachs, 2013), Benjamin Sachs explores whether the argument I have provided for grounding indirect obligations of justice to conserve natural resources for future people really succeeds. Sachs insightfully points out that it does not necessarily follow from the fact that profligate individuals increase the obligation of others to conserve natural resources, that those others can insist that the profligate individuals do their (...) fair share. Sachs argues that this only follows if those who are obligated to pick up the slack have been wronged (Sachs, 2013, pp. 209). Furthermore, he argues that in order to be wronged, they must have been harmed (Sachs, 2013, p. 210). And since the obligation to conserve natural resources is, according to Sachs, not taken seriously, those who do not pick up the slack for others’ overuse are not being harmed. Therefore, Sachs concludes, my argument for indirect obligations to conserve natural resources for future people is on shaky ground. (shrink)
