I read through the article and still can’t see how my post is related to facism. If we assume a number of X humans with an average environmental footprint of Y that leads to an overall footprint for humanity of X * Y.
If we want to bring that number down, this can by achieved by lowering either of the factors. If you want to cut pollution by let’s say 50% with a constant polulation, it goes along with harsher cut backs for the individuals’ lifestyle. Looking at the current discourse, such cut backs are highly controverse and measures in that direction are rarely accepted (‘they want to take out meat’, ‘they want to take our cars’ etc.).
If the number of humans decreased by 25% due to a naturally lowered birth rate, it means that the individual pollution must be lowered only by 33% instead of 50% to achieve the same result. I would argue that less individual impact will lead to a higher acceptance for a environment-friendly humanity.
If I wrote ‘kill the poor’ or something like that I’d get your point but I just said that fewer people will have a positive impact on nature. Which is not facism but a simple fact.
By the way. Your liked Wikipedia article also warns about the term ‘ecofacism’ being misused by the far right to discredit any form of pro-environment statements. So, please think twice before if you really want to use that term and call random people fascists.
Detractors on the political right tend to use the term “ecofascism” as a hyperbolic general pejorative against all environmental activists, including more mainstream groups such as Greenpeace, prominent activists such as Greta Thunberg, and government agencies tasked with protecting environmental resources.
