 Indeed, he finds traces of deep ecology in the "biological reduction" of Nazism, an ideology many "organicist thinkers" have found appealing, including Herbert Gruhl, a founder of the German Green Party (who subsequently left when it became more left-wing) and originator of the phrase "neither left nor right, but ahead".Kovel warns that, while 'ecofascism' is confined to a narrow band of far right intellectuals and disaffected white power skinheads who involved themselves alongside far left groups in the anti-globalization movement, it may be "imposed as a revolution from above to install an authoritarian regime in order to preserve the main workings of the system" in times of crisis.Bioregionalism, a philosophy developed by writers like Kirkpatrick Sale who believe in the self-sufficiency of "appropriate bioregional boundaries" drawn up by inhabitants of "an area", has been critiqued by Kovel, who fears that the "vagueness" of the area will lead to conflict and further boundaries between communities.
