Understandably there was outrage this week when a Copenhagen zoo killed a healthy two-year-old "surplus" giraffe, cut it up and fed it to the lions.
That it was done in front of school children, and that the redundant giraffe had big gentle eyes and a name, Marius, starts to make it unpalatable.
Marius was part of a breeding program at the zoo, but his genes weren't needed. The zoo was concerned about too much inbreeding. The giraffe had to go.
