It's obvious from reading these posts that some of us poles apart on this subject. Whether to sterilise or not, sentiment or not and so it goes on. Quite frankly from where I'm sitting that little giraffe should never have been born in the fist place, how to prevent that? well, I would have thought keeping boys away from girls, except where there is a proper selected pair to breed from, could be the answer, result, no unwanted, incompatible, surplus to requirements babies. Seems a simple solution to me, but perhaps I'm wrong. I can't help feeling too, that wild animals are best left where nature intended them to be, in the wild; sure they would become extinct but then so did others before them, to be replaced by future creatures, as has happened in the past, and perhaps as nature intends. Even with the best of intentions captivity is unnatural for these creatures, and, if we are honest, done mainly as money spinners with conservation to appease our conscious!!
