Well, among other things that affected my administration of affairs at Brookfield, one of the obvious ones was the Endangered Species Act, which prior to the 1970s, that didn’t exist. I mean, those restrictions were very sporadic, as I say, in terms of the okapi, Ringling Brothers was prohibited from exhibiting the animal they owned. And so we came to possess that animal. But really prior to that time, there weren’t the necessary standards in terms of the maintenance of the collections and the records thereon, and so on, and so forth. So that was a significant development, I feel because many of the creatures kept in zoos were rare, were apt to be considered, if not on the United States endangered species list, they were certainly considered under pressure by international bodies such as the International Union for the Conservation of Nature, which I became associated with pretty early on in my tenure as the director.
