The ethics of terraforming

I apply an agent-based virtue ethics to issues in environmental philosophy regarding our treatment of complex inorganic systems. I consider the ethics of terraforming: hypothetical planetary engineering on a vast scale which is aimed at producing habitable environments on otherwise "hostile" planets. I argue that the undertaking of such a project demonstrates at least two serious defects of moral character: an aesthetic insensitivity and the sin of hubris. Trying to change whole planets to suit our ends is arrogant vandalism. I maintain that these descriptions of character are coherent and important ethical concepts. Finally, I demonstrate how the arguments developed in opposition to terraforming. a somewhat farfetched example, can be used in cases closer to home to provide arguments against our use of recombinant DNA technologies and against the construction of tourist developments in wilderness areas.
