Read here. The religion of environmentalism is simply the means to gain control and power over people, usually via different forms of punishment. Most forget that Hitler was the world's first political environmentalist; fortunately, we have today's self-important Germans reminding us of the dangers of persons on fanatical crusades, who literally will sacrifice the individual for the "good" of the community. We've been there and done that - death trains for all non-believers doesn't work so well.
Whether the more accurate term is eco-Nazis or eco-fascists, Germans are not the only ones espousing fanatical environmentalism and world governance concepts. Read additional articles here, here, here, here, here, and here about the environmental fascism/governance that has been on recent display.
So, the next time you see a Greenpeace or "Save the Whales" or "Meat is Gross" or other self-righteous environmental bumper sticker, think eco-Nazis, because ultimately, that's what it means.
