Like a great deal of aerial photography (Bradford Washburn's naturalistic mountain work immediately comes to mind in this connection), Emmet Gowin's meticulously detailed portfolio depicting man's ambition writ large upon the surface of our planet can often be 'read' as much as abstract art as documentary record. As art, this series of images of a wounded planet is so deceptively compelling it is easy to become lost in the sensuousness of the aesthetic moment Gowin repeatedly creates and forget that the subject matter being systematically explored is intrinsically disturbing and of concern. Indeed, the experience of finding so much beauty in landscapes of man-made desolation and ruin is unnerving. Yet it is undeniable that from a distance the patterns on the Earth made by irrigation pivots, toxic chemical ponds, missile burial trenches, mining pits, and numerous other manifestations of human 'development' without limits are endlessly unique and dramatic. Paradoxically, it is precisely this nexus of visually stimulating, geometrically intricate imagery generated in the context of wanton exploitation and destruction of the land that sustains the narrative and aesthetic power of Changing The Earth. One is absorbed in the beauty of the photography just long enough to catch sight and become painfully aware of the pervasive, intensely consequential, problem that demands attention and thought. Thus lessons for the future abound in the pages of this volume! One day our way of taking the Earth for granted by first depleting its resources for immediate gain and then dumping what is no longer wanted or useful wherever is convenient, will be seen as the opulent conceit and obscene luxury that it surely is. Until that day, studies like Changing The Earth bare witness to our collective folly, greed and irresponsibility.
