Training crows to pick up cigarette butts for food
Back in college I did a paper on if this was ethical or not for my bioethics class, I warn people to really take a step back from the positive possibilities with something like this and understand that these are wild animals being trained to become slaves to benefit our human failings and appetites.I would definitely draw a line between this kind of domestication and the domestication of animals by our ancestors for our own survival. This is trash created by humans, and the human responsible should be the asshole who picks it up. At that point, we're the ones that should be domesticated, not crows.
