Aren't most of these large marine animals in captivity rescues? Like you said, isn't it better than leaving them in the wild to die? Why not make the law so they can only have them for rehabilitation purposes and then release them (if possible) when well? Don't marine biologist learn a great deal being in close contact with these animals that can benefit the animals in the wild?
The belugas were Canadian or Russian caught. The dolphins have tended to be "Japanese Injuries." To the best of my knowledge, only the false killer whale is a local rescue.
