Scientists largely agree that Earth is in the midst of a sixth mass extinction, so we will be called upon to say goodbye to animals with increasing frequency. Unfortunately, the average American knows pitifully few ways to do so. If you ask anyone on the street, their list will likely stop short after just two: “In a while, crocodile” and “See you later, alligator.” In light of this, we offer the following non-exhaustive list of animal farewells:
