The slide with the sharks was only one of the ones mentioned and I doubt I'd go there for the same reason. There are some circumstances that I agree with animals in captivity such as trying to breed an endangered species so that it can be reintroduced into it's natural environment or if it is somewhere like the Cornish Seal Sanctuary who treat injured animals, releasing them back into the wild where they can or taking the best care possible when that isn't an option.
