I will admit to not reading the original post's article, but I've been thinking about this a little lately and thought I'd contribute. The big point is that AT THIS TIME, zoos exist so that people can see animals. There are plenty of other great reasons why they should exist and wonderful ancillary things they accomplish, but the primary, root reason zoos are around is for people to see live animals. Therefore, the primary concern should be to get people to see the animals...and unfortunately, people (at least in the US) are not patient. By and large, they will not wait around for an animal to emerge from the underbrush. So...the setting itself (to Zooplantman's point) is a secondary goal that needs to be defined when designing the exhibit. Are we trying to educate about the ecosystem as an entirety, or are we primarily concerned with people learning about the animal itself. In a perfect world, of course, we'd be targeting the whole ecosystem (and the animal would be a part of that as well). My question is...do we just simply respond to what the guests want / need right now, or do we work to push them beyond their comfort zone? Should we continue to build bigger, wilder, more natural, and hope that these efforts start to shape the evolution of their behavior (becoming more patient, etc) as they visit our institutions??? Or by not responding to how they behave now, are we sacrificing educational benefits we have in our grasp?
