Would like to add that I'm not saying people shouldn't read the sign. Sign are educational and with some simple interactive facilities, children and adults would gain a lot from it. However, I do know a lot of inaccurate signs and some not-so-good ones. (like printing out a paper and said "RACCOON" yet the photo is a coati and the animal is a raccoon dog, yes i'm pretty sure a chinese zoo do that) If zoos don't do their stuff right they shouldn't expect the visitors to.ok sure people dont read the sign. But ask yourself, when you walk into an aquarium with tank as big as Georgia's, do you read all the sign there? Is the sign really sufficient? or how about a huge walk through aviary? How about in an art museum? Do you understand all the things written in the sign? People dont read sign not because they're ignorant, but because they aren't interested in absolutely everything. Also people want to enjoy themself in zoos not reading boring facts, and thats understandable.
I think zoo should be a form of "edutainment", by attract people to the zoo they can have fun and learn too. People don't read sign because they don't want to learn (no one want to learn the things they aren't interest in a Sunday morning) That can be true about the playground too. Playground is not a waste of space because children will go, and children will look at animals and learn while having fun too. Zoos should make ways to attract people and children to learn, not forcing them to read a boring sign. (So educational show is a good idea! Animal ambassadors will interact with people and they will hear from the keeper, thus leading to a more interesting learning experience)
