Last I heard the National Socialist were “Green”.
“The purpose of exploring Nazi environmentalism is not just to upset the greens. If environmentalism were a curious but peripheral aspect of National Socialism, it would be of no real historical interest.
Environmentalists could be forgiven for saying, Ah well, it just goes to show, there’s a little bit of good in the worst of us. But environmentalist ideology was not an accidental, optional-extra to National Socialism.
As we shall see, green ideas were at the *core* of Nazi thinking. The German Volk and Nazi movements marched beneath the banners of ‘Nature’ and the ‘organic’. However, what follows here is not simply a potted history of Nazi environmentalism. It is, at the same time, a brief history of early environmentalism writ large.
As will become clear, it is not so easy to draw a line between two types of green thinking.

The same author of the American Thinker article mentioned above wrote a book called “Nazi Oaks: The Green Sacrifice of the Judeo-Christian Worldview in the Holocaust.” It is not an easy book to read, but very well informed with piles of information on the subject - https://www.amazon.com/Nazi-Oaks-Sacrifice-Christian-Worldview/dp/0692381465.
