What about the killing of healthy humans? Where is that placed in the pantheon of ethical issues?
Killing of healthy animals for food to feed people is good. Killing of the healthy animals just for sport - not so good.
However, when it comes to zoos and how humanely they take care of their animals, I'd like to think they could've found a better solution by shipping out those lions to another zoo or a more humane way of taking care to keep the lions alive.
As for giraffes, they're far more fragile and shipping them around is very risky, I understand. I think zoos being allowed to have giraffes at all
should be far more restricted.
However, it shocks me that those zookeepers (and veterinarian) dismembered the giraffe in front of an audience and, especially so, in front of children. What stupidity!
