Some European zoo enthusiasts either zoo people, or non zoo employees, keep their life list. Sometime, 1000. Sometime 1500. Someone said, oh mine is 1500 something something. And they even come up with a solid list of number of zoos in the whole world. That aspect, the global aspect, American zoo people should learn. Europeans may not be richer, as American citizens, however. They come to you, yes to learn, to look at our zoos, but not the other way around.
