LINK: Environmental Ethics and the Expanding Problem of Evil
Abstract:
The problem of evil is that morally gratuitous suffering and destruction is evidence against a benevolent and potent god. Often cases of this evil are restricted to human suffering, but if the moral universe is expanded in the fashion associated with environmental ethics, the scope of morally significant suffering and destruction grows. Consequently, the wider the scope of the moral universe, the problem of evil becomes harder for theists to solve.
