Regardless of your opinion re: animal capturing, animal abuse, and animal rights, you’re making some pretty iffy arguments here.
It seemed to me that the primary thrust of the movie’s message was that the animals “belong” in the wild, and taking them out of nature makes them sad or angry…
This doesn’t really convinced me of much. It seems that with an unlimited supply of food, a lack of predators, and generally a longer life than that of wild animals, these contained animals wouldn’t have much to complain about if they could voice complaint. What do you think?
None of the things you listed would make you happy were you captured. Assuming that the animal is capable of being depressed - which, in the case of dolphins and many other captive animals that are used for amusement is entirely true - then it’s pretty safe to assume that none of the things you just listed would keep the animal happy. Many captive animals used for amusement are significantly smarter than cats or dogs, and you can pretty readily tell that dogs, at least, can get depressed when in too confined of a setting (this, of course, depends on the breed of dog - some, like my shih-tzu, couldn’t be happier than if they have a comfy home and an occasional walk, while others desperately need to be outdoors to run around on a regular basis in order to be happy).
Oh, in regards to my topic title, orcas’ dorsals fins sag in captivity, basically because they don’t need to use it. This was supposed to make the viewer feel some kind of anger toward the captors, but in my opinion, if they no longer need to use the dorsal fin because they are safe in captivity, why does it matter if they can’t use it?
Again, this is an entirely non-sensical argument. Assuming that the animal is capable of being depressed or unhappy, which we have already established that it is, one can pretty safely say that making an animal’s body parts useless is not something that will make that animal happy. If you were put in captivity, given food and kept safe from predators, we could remove your arms and legs. You wouldn’t need them, after all - you’re fed, bathed, et cetera, by your caretakers, so there’s no cause for concern. Right?
There is still argument to be had whether animals have rights or not. I’m at odds with most Objectivists on this point. But whether or not they do is pretty irrelevant to your specific arguments. Human brains are not, as we like to assume, so significantly more complex than the brains of other animals such that we can’t find common ground. The common ground is actually pretty significant. Animals are capable of depression, they’re capable of being happy or unhappy or a wide variety of other emotions, they’re capable of basic reasoning, some animals, especially some larger mammals and some bird species, are capable of concept formation and basic abstract reasoning. They’re not on the same level as humans, but much of the reasoning that applies to humans and human happiness also applies to animals and animal happiness. If you cause significant bodily harm to an animal, if you keep it pinned up in a space too small for it, if you keep it from exercising itself in the various ways that keep animals in the wild happy, it will, undoubtedly, become unhappy and depressed. That’s not really hard to figure out. So yes, of course the animals you are referencing would have reason to voice complaint, if they could.
The only question is, do you give a shit whether or not the animals are suffering? Again, I’m at odds with most Objectivists on this point, so I won’t voice my personal opinion here - but most Objectivists would likely say that the animals have no rights, so you do not, necessarily, have to give a shit that you’re inflicting direct, intentional harm upon them.
