I take it that you decided to not read the article?

Here are the last few paragraphs:

'How can anyone read the Nazi Heidegger, or the writers of the Volk movement, or indeed Mein Kampf, and say, with a straight face, that environmentalism started with Rachel Carson? The Nazi Martin Heidegger is to the tips of his fingers, a romantic anti-capitalist. He is, to the toes of his fascist jack-boots, an environmentalist.

Should we be at all worried about any of this? After all, modern environmentalism, to many people, seems so innocent. But in the words of Bruggemeier, Cioc and Zeller (editors of How Green Were the Nazis?), ‘The green policies of the Nazis were more than a mere episode or aberration in environmental history at large. They point to larger meanings and demonstrate with brutal clarity that conservationism and environmentalism are not and have never been value-free or inherently benign enterprises.’ We should heed the warning of Lukács, that, ‘fascist demagogy and tyranny was only the ultimate culmination of a long process which initially had an “innocent” look’.

Green thinking was not a side-line for the Nazis. The idealisation of nature and the organic, the nostalgia for the Middle Ages, the anti-capitalism, the hatred of bankers, the hatred of cities and industry, the idealisation of peasant life … all this defined their poisonous ideology. It was the green attempt of the Nazis to recreate a peasant society which led them to invade Poland in search of ‘living space’. It was their green nostalgia for the Middle Ages which led to their ‘blood and soil’ racist ideology. It was their green anti-capitalism and loathing of bankers which led them to hate Jewish people. It was their green rejection of the Judeo-Christian tradition and of the Enlightenment and its humanist values, and their green return to pagan animal-worship - their idealisation of pre-civilised barbarism as more ‘authentic’ - that led to them to treat humans as worthless creatures with no more claim on our sympathies than viruses and pests. Green ideology was at the core of National Socialism. When we wonder what diseased thinking could motivate people to turn on the gas taps at Auschwitz, this is where we must look.'

It's a fairly long article and very interesting. But you can go ahead and use "Godwin's Law" as your excuse for not reading it.
