9 Humphrey, for example, motivates his ethical inquiry into earthworks by means of a somewhat similar point: ‘an earthwork is ethical if and only if what it does to the environment is ethical. This requires us to look at the earthwork as a mark and not only as art. In seeing earthworks in this way, the implication is that earthworks should be ethically judged by the same standard … that all other such marks are judged by - marks like strip mines, dams, and golden arches.’ Ibid.
