What we shouldn’t forget, exhibits that have been, that look bad nowadays, but have been built 60 years or so ago, may have been, at that time, when they were built, some best and most modern exhibits ever built. Everything humans do become old and outdated. And I think the more natural an exhibit is, the longer it will stay acceptable for the animals, for the visitors, for the staff. So I plead for as natural as possible exhibits.
