Imagine you are driving along an expressway and suddenly you are slicing a hare -- inscribed into the landscape to right and left -- in half. Truly a most uncomfortable and powerful metaphor for what we are doing to nature.

Using the landscape as an expressive medium is not new. Consider the sacred and celebratory prehistoric images carved into English chalk hillsides. Or the geometric mystic marvels that can only be fully appreciated from a great height over the Plains of Nazca in Peru.

German-Austrian artist Hans Joachim Bauer goes one step further, however. He brings a gently expressed but profound moral anger to what he terms "land art."
