There have been a great many surveys, most of which indicate that zoos do make a difference. We specifically at the wildlife conservation society in New York’s Bronx Zoo undertook a survey to see what the new Congo exhibit had done. I was not only gratified, I was downright hornswoggled. I was very surprised to discover how much people had learned in that exhibit, how their views had toured, how the knowledge they had when they came in had been refined. So I think zoos could make a big difference in that way, but many zoos also have education departments and those education departments can do marvelous things. The Bronx Zoo has had a wonderful education department for many, many years based largely on the work of a fantastic girl, now retired name, Annette Berkovits. Annette initiated programs all over the country. Virtually all of the 50 states had teachers that were trained at some point at the Bronx Zoo.
