"Nazi Ecology" deconstructs the anti-Semitic historical background of the early German green movement of the 19th century which was absorbed by National Socialism that became the foundation for biological Anti-Semitism in the 20th century. While many have decried the industrial nature of the Holocaust, such views cannot explain the motive behind the greatest crime of the 20th century. Nazi racism was foreshadowed by the Social Darwinism of German Romanticism in the 1800's that laid the ecological foundations for what is otherwise known today as environmentalism. "Nazi Ecology" explains why the Holocaust is best understood as a modernized form of human sacrifice carried out under ecological/biological camouflage that is rooted in the sacrificial oak imagery of ancient paganism. The word Holocaust itself means "whole burnt offering."
