The tortoise had a whole lake practically with an island and shubbery. What kind of loonatics own thi place.
So what makes a tortoise less special than a bear?
The sad truth is, there are many bad exhibits around the world for large and small animals alike, however there are also many, many good exhibits for these same animals.
Would you have expressed such a strong opinion if the tortoise was in a pen not much bigger than itself?
It is also neccessary to educate people about animals in the wild, not just the individuals in the zoo, because people go to the zoo to see animals that would normally be inaccessable for them. (This also increases the conservation message) Would you like people to come away from a zoo thinking elephants only eat hay or monkeys eat primate pellets and chopped fruit. It is important to describe their natural diet in order for visitors to actually learn something!
The education in zoos isn't totally meant to be about the individuals in the collection. A modern zoo should strive to teach it's visitors about conservation and animals in the wild.
Regarding you comment about the "public-paying-your wages", there is a large number of people on this site who have no professional connection to a zoo (me included) however these are people who are deeply interested in zoos and know a thing or two.
The main point of this thread wasn't to ridicule the average visitor, (who most people would agree, keep zoos afloat) but to list common mistakes made. One of the earlier posts actually demonstrated a scientific study!
ashley-h is right, you should perhaps think about an animal rights group...
