When Copenhagen Zoo decided to kill the young giraf Marios and then dissection it in front of a large crowd, including fascinated-looking children, it prompted outrage and protests around the world. The zoo’s scientific director, Bengt Holst, got death treads but didn’t apologize for the act: “We have been very steadfast because we know we’ve made this decision on a factual and proper basis. We can’t all of a sudden change to something we know is worse because of some emotional events happening around us.”
