invasive
Explanation
This comic introduces the concept of an "invasivore" -- someone who exclusively eats invasive species that are degrading local ecology. When asked to explain at what appears to be a social gathering, the character describes their diet: the more invasive a species becomes, the more delicious they find it. This is presented as a perfect alignment of personal values with behavior.
The other character responds enthusiastically, calling it "a great way to align your behavior with your values!" and asks to hear more about how it works in practice. The comic plays on the trend of ethical eating philosophies (veganism, locavorism, etc.) by presenting one that sounds logical on paper -- eating invasive species helps the environment -- but the practical implications are darkly comic. The person is shown holding what appears to be a large knife, hinting that "invasivore" dining might involve some rather hands-on food preparation. The humor lies in the gap between the noble-sounding principle and the likely grim reality of hunting and eating things like feral hogs, Asian carp, or kudzu.
