Abstract
The degradation of natural resources in the environment is, technically speaking, a form of depleting a public good. Public goods are notorious for free-riding among egoists, but the marginality of individual contributions provides no less an obstacle, both to moral duty and motivation. This article discusses the problems of minimized and missing causal involvement on the empirical side; and, in the applicability of classical moral arguments, on the ethical side. It. suggests that individual responsibility is derived on the basis of implicit advantage-taking from participation in collective action.
