Maybe we have a moral obligation to undo the damage we’ve done?Not necessarily talking about mammoths here, but more recent species that we’ve made extinct. If it can be done in a way that’s not just to make zoo animals, but actually restore them in the environment like we’ve reintroduced some animals into areas they’ve been driven out of.
Might as well put that effort towards halting the ongoing mass extinction of more animals, before worrying about bringing back facsimiles of the ones we've already eliminated
