There's a more impactful video of it crying and howling. It was pretty sad, and is not unique to China. Our captivity of dolphins and orcas is pretty morbid given what we now know of their social bonds. China will surely do nothing nor care what we say, but with what we do. I went to seaworld as a kid, and my 20min of excitement doesn't justify it's lifetime in captivity. I think that sealife conservation has become powerful enough to create groups such as the sea sheppard's group, that change is needed. 

We Alaskans have this on point with the Sea Life Center who rehabilitates and releases. Those that would not survive in the wild any longer, are cared for the best they can.
