To influence the upcoming climate conference inn Copenhagen Greenpeace France and Spencer Tunick organised a demonstration / installation / work of art in a vineyard in Burgundy: 700 naked people in the vineyard. The purpose was to draw attention to the effects that climate change will have on agriculture, and specifically wine growing, in France. You can now watch the video from the happening, 700 nude people in the vineyard: https://www.greenpeace.fr/tunick/ and www.treehugger.com (But one assumes that at least at that occasion all participants appreciated the unseasonably warm weather.)
