flesh-2
Explanation
This single-panel comic shows a person in bed waking up in apparent horror while screaming "FLESSHHHHHH! FLESHHHHHHHHHHHH! FLESH OF MANNNNNNNNNNNNN!" There is another person sleeping next to them, seemingly undisturbed. The caption reads: "In retrospect, it was clear how the ethical invasivore movement would wind up."
The joke requires understanding the concept of "invasivore" eating -- a real movement that advocates eating invasive species as both a culinary adventure and an ecological good deed. Invasive species (like Asian carp, kudzu, or feral hogs) damage native ecosystems, so the argument goes that eating them is ethically virtuous: you get a meal and help the environment.
The comic takes this ethical framework to its darkly logical extreme. If the moral calculus of invasivore eating is "it is ethical to eat species that are invasive and damaging to the ecosystem," then humans -- arguably the most invasive and ecologically destructive species on the planet -- would be the ultimate ethical target. The "ethical invasivore movement" has thus devolved into cannibalism, with the person screaming about "flesh of man" like a zombie or a character from a horror movie.
The humor is in the phrase "in retrospect, it was clear" -- suggesting this outcome was entirely predictable from the premises, even though nobody saw it coming. The comic satirizes the way well-intentioned ethical movements can produce absurd conclusions when their underlying logic is extended without limit. It also plays on the horror-movie trope of someone waking up screaming, but here the nightmarish craving is presented as the inevitable endpoint of a trendy food philosophy.
