@NZ Jeremy: Even if he did-judging from the smiley-his interpretation was correct.
Yours, however, "you'll post whatever you think can get a rise out of as many people as possible..." isn't; this is not my intention. I just want You all to look at things from different angles, to see flaws in Your individual argumentation that could be corrected and nullified by combined cogitation-to achieve something better. Maybe a smarter, more effective standpoint that could prove valuable when dealing with people who are really against Your argumentation and want to prove You wrong. This is especially true in terms of zoos; I've met a few of the anti-zoo lobby so far, and learned some important things from that. One thing is that You should be prepared to offer them answers they can't denounce easily; be prepared that their argumentation might look pointless, irrelevant or extreme to You-but that they can use this to corner You and destroy Your points without giving You a chance. Maybe that's my role in this forum: assume the role of the bothersome gadfly in Socratic sense, so that we together can find arguments and ideas that can both stand their ground against critics and maybe be of benefit for the future of zoos.
Another thing is constructive criticism combined with realism; there exists nothing like a "perfect" zoo world, and addressing these inherent problems instead of positivizing, belittling and even ignoring them will benefit the zoos and animals within. Additionally, You should also keep the consequences, the practicability and plausibility of Your critism and derived suggestions in mind.
So, if You state that "there should be no elephants in urban zoos", You also have to think about the possible aspects, the pro's and con's and consequences on all levels, of such a statement-and do not consider the well-intentioned references as personal insults, but as helpful in terms of generating deeper thinking about the subject-and thus not generating senseless lenghty mutual vituperations, but productive conversation. So please, and this is also true for patrick and others, think about it next time, someone, most likely me, replies to Your statement: "I contradict, because..." that this is NOT meant as
a) point-scoring or dogmatic hair-splitting just to "win" a discussion
b) a personal insult to debase You
c) an attempt of a belligerent trouble maker just trying to make up a senseless discussion,
but in the way mentioned above: more food for thoughts, i.e. asking You to take another look at Your statement from another viewpoint, think about this objection and either incorporate or vitiate it in a reasonable, polite, comprehensible and generative manner. I enjoy discussing with You guys because it gives me an interesting insight in international zoo attitudes-but I don't enjoy always having to lenghty justify what I wrote because someone feels offended, misread, misinterpreted etc. and feels he/she has to snap at me, resulting in hardened feelings.
And no, NZ Jeremy-nobody has built Conway's "Bullfrog Exhibit" -yet. There have been tiny attempts to do such, but none of these experiments has proven to be long-lived or spread all over the world, may it be Denver's Komodo Dragon exhibit or Vienna's Zoo aquarium. Independent as well as zoo-based studies have shown that despite the nice, beautiful "Amazing engrossing" exhibit signs, only a small percentage of the visitors actually reads these-and the kids just hammer randomly on the interactive computer counsils etc. until they're broken. This is btw. another argument anti-zoo people love to use; a possible response, derived from a quote by Grzimek, could be that this small percentage of people is at least something. However, let us also think how to improve this aspect; f.e., the educational value of some US zoo signs isn't bad-but how could this be improved to grab the attention of more visitors? How could You make "boring" animals more interesting-without investing in too many fancy, fragile, expensive and sometimes misleading electronic gagdets? That's just the "food for thoughts" I'd like to achieve...
Lastly: I did not change my viewpoint. I didn't say that I agreed that Your suggestion would make Partula snails more interesting, NZ Jeremy. All I did was simply ask why such an exhibit does not exist-in terms of Partula snails. And indeed-there is not such a Partula snail exhibit in any zoo worldwide. The question-"why"-is most possibily answered by the low cost-attraction/effect ratio I mentioned above. "Oh", You might cry out loudly, "this is just pointless controversial aiming at extremes, attempting to lead a discussion". No, it's not; it just underlines that there are species that are not attractive for the majority of visitors, no matter how much funky gadgets You would build around them (most likely, the gadgets would be more interesting than the animal itself), and that in terms of successful & far-reaching educational values, zoos still have a long way to go.
So the question, maybe leading to a thread on its own, should be: How to improve the educational value of zoos-even in terms of "boring" animals?
Chlidonias' hint about the kiwi enclosure for example is highly interesting-it means that so far all kiwi exhibits I have seen in zoos are wrongly constructed. Adding permanent guides (and "bouncers" in terms of noisy children) is a good idea-but I know that a lot of zoos would now object that this would be too expensive-and might even anger visitors(You won't believe how some parents react when their ill bred brats are reprehended by someone-even if it's completely justified..).
