Well this is an old question. The main thing is not to have much space. You have to arrange yourself to the space you have in in front of you, you have available. So this leads to a reduction of the number of species. But it takes to a better living for the animals and to a better exception of the visitors, better to have a smaller number of species, but to keep them very well. And so that people don’t think, oh, this is a prison of animals. So an exhibit has to look like a part of the nature at the zoo.
