Given the damage done to our environment, you'd actually expect there to be more eco-fascists at this point, but the people responsible for the most damage have so severely buried their heads in the sand, they focus just on fascism without the eco part.

I do worry that as climate change gets worse and worse, we will see much more of it. I think a big part of ecofascism is that the out-groups are going to be disadvantaged people living in the areas most affected, so those of us living in the relatively affluent parts of the globe won't experience it for quite some time.

You can look to many historical "conservationists" like John Muir as prototypes taking areas people have lived in for thousands of years, declaring them "land untouched by human hands" and kicking the people living there out to "preserve" it.

I think just generally, there are way way more people doing ecofascist things than there are people who would best be described as "ecofascist". Similar to how many fascists are zionist and antisemitic, many fascists are malthusians who proclaim that the problem is people in the global south with 1/50th of their carbon footprint.

Fascism is hardly ever ideologically consistent.
