Abstract

People evolved as part of an ecosystem, making use of the Earth’s bounty without reflection. Only when our ancestors developed the capacity for moral agency could we begin to reflect on whether we had taken in excess of our due. This outlines a ‘green libertarianism’ in which our property rights are grounded in fundamental ecological facts. It further argues that it is immune from two objections levelled at right- and left- libertarian theories of acquisition: that Robert Nozick, without justification, divided people into those who were able to acquire unowned resources, and those would could not; and, that left-libertarian attempts, such as Hillel Steiner’s, to separate choice from circumstance cannot account for the fact that not only people’s decisions to have children, but even their decisions to continue living, affect people’s entitlements to use the natural world
