The reappearance of fascism in many western countries threatens all the freedoms the left movements have managed to gain over the last half century. Equally disconcerting is the attempt by fascist ideologists and political groups to use ecology in the service of social reaction. This effort is not without long historical roots in Germany, both in its nineteenth-century romanticism and in the Third Reich in the present century. In order to preserve the liberatory aspects of ecology, the authors, as social ecologists, explore the German experience of fascism and derive from it historical lessons about the political use of ecology. Comprised of two essays—"Fascist Ideology: The Green Wing of the Nazi Party and its Historical Antecedents" and "Ecology and the Modernization of Fascism in the German Ultra-Right,"—Ecofascism examines aspects of German fascism, past and present, in order to draw essential lessons from them for ecology movements both in Germany and elsewhere.
