ABSTRACT Peter Selz engages Helen and Newton Harrison in discussion about their expansive career in ecological art. The artists reflect upon the influences of Renaissance artists and the Bauhaus on the development of their approach, and they chronicle their concern with survival at progressively larger scales. In their recent Force Majeure series, working at the ecosystemic level, they present poetic meditations on prospects for the security of all living things as land, food, fresh water and other species diminish.
