I know that a lot of you are against keeping animals in zoos, but how else can animals safely observe humans? Think about it.  Animals in the wild would never get the chance to view some of our stranger human characteristics unless we built them a home at the zoo so we can parade past them for their entertainment (at our own expense too!)

Otters are an excellent example of this. Usually otters are floating around in remote coastal areas with very little human contact (except for the few they see in those floating machines with strings hanging off them). But put them in a zoo and they can see really cool human behavior - like the sounds humans make when they see otters holding hands.
