The National Socialists of the Third Reich were true environmentalists. They had a great respect for the natural world and its immutable laws, seeking the ‘organic’ not only in their food, but also in their community organization, building projects, and political leadership. This outlook was in stark contrast to the Communist machine, which had little regard for the sanctity of creation.
