The zoos need a lot of judgement. I love zoos, I love visiting them and for me it is the only way that I am likely to see exotic species. However - and this a big BUT - zoos or their programs should not be excempt from criticism, especially from those who are not insiders. Zoos conservation work is based on a shaky foundation. Yes they do many wonderful funding and great work but lets not kid ourselves - the number of animal species saved by zoos are small.
Zoos like all organisations need constant criticism to keep them improving themselves, otherwise they will become slack and try to get away with all sorts of things.
I am now borderline anti zoos simply because they all could do so much better. Recent discussions about bears, small cats at Melbourne and so on have shown how, for even small amounts of money could improve things for the animals.
Back to snow leopards, you still haven't shown me how decreasing the potential male founders from three to two is a positive thing.
