When, on 7 December 1972, Blue Marble-the first clear photograph of the whole earth-was shown, we immediately understood its message: this is the territory. Although it had long since been proven that the Earth was round and finite, it took an image to really let especially that finiteness sink in with our collective consciousness. From then on the Earth was indeed understood as a territory: a well-defined and limited terrain and the only one to inhabit and to farm, at least for now. It is no coincidence that ecological movements rapidly gathered momentum in the early 1970s.
