Dude, this is the most uncontaversial take in conservation.
So, again. Your Malthusian eco-fash hottake can literally be disproven by the simple fact that elephants exist. Animals can and will evolve to live within the means of their environments. Even humans have been thoroughly documented to be capable of such. So your pretensions that a “Reindeer Apocalypse” is imminent is… what, exactly?
Are you absolutely positive you’re a leftist? Because people who are left of center don’t typically call each other “eco-fascists” for pointing out easily verifiable facts about ecology that do not involve human interference in any way.
