Mixed. I don't aggree with zoos in Wisconsin having animals from South America and Africa. The lions and giraffes and such have to be in small indoor enlosures or out in the snow during the winter. Those types of animals don't belong in our climate, just as polar bears don't belong in zoos in florida.
Its nice that some species can be saved, or that zoos do educational programs. But how much education do you get from watching a lion or a tiger roam a 1/4 or half acre enclosure for 20 years? The amazing thing about our loacl zoo is that the exotic animals have tiny enclosures, but the native animals have huge spaces. They have several acres for white-tailed deer. Nobody in WI wants to see more deer. We have them in our back yards in the city. I guess the exotics have to be in small enclosures to ensure the public can see them. Poor creatures.
