Now my full response to Blackfish and it's supporters.
I’m going to start off by pointing out that you cannot become an expert on marine biology or animal behavior by watching an 80 minute movie. Luckily for you, I have a few years experience in the field working at an aquarium that does not have large marine mammals but have learned about animal behavior and training in captivity and I’d like to give my take on the movie itself and the backlash it’s caused.
The first thing I want to talk about is when Tilikum was captured. Back then, there was little regulation or industry standard about marine mammals. I will fully admit that the first “park” he was in was terrible, but that was just like every other zoo and park at the time. It didn’t matter if it was someplace like SeaWorld or a government owned aquarium, I can guarantee you that it’s animal care procedures were barbaric compared to today. It wasn’t until fairly recently that animal facilities learned how to keep animals properly. I have no doubt in my mind that if Tilikum was never at that first park, he never would have had as many issues. The same thing goes for animal collection, whales in the wild are more likely to be hunted for food than captured just for parks. There are rescues, but they are not able to go back into the wild and survive.
There are just so many things with the way it presents it’s “facts”. First of all, there is an insane amount of speculation and hearsay. When they present the incident at Sea Park, they bring in eye witnesses who are untrained guests from over 20 years ago to point out which whale of the three attacked the hotel which consisted of two additional dominant females. There’s also the incident where the guy was found in the pool one night. The conspiracy theorist level speculation feels like the movie is trying to say that SeaWorld not only knew about the guy, but almost fed him to Tilikum. This movie takes every potential hole (whether it’s a real hole or not) and blows it up to make the park look like a saturday morning cartoon villain, all while maintaining it doesn’t have an agenda. There were lots of comments said that bothered me, and that would take too much time to address, but one bit that bothered me in particular was a guy saying, "There are no recorded incidents of a whale attacking a human in the wild.". This is because the water where these whales live is very very cold. The guy is pretty much saying, "There are no recorded incidents of a person getting hit by a train on the moon, so we should ban trains on Earth."
There’s also the point where the movie tries to convince the viewer that SeaWorld is trying to produce a hyper aggressive killer whale line on purpose….I don’t feel I have to explain just exactly why this is silly.
Now let me talk about animal intelligence, specifically how much we know about it: very little. As humans, we have this awful habit of humanizing animals as a way to identify with them and this movie does a horrible job by making you sympathize with them. This causes a few problems, including the fact that they are, in fact, still animals. Don’t get me wrong, I love animals, and I’ve been surprised about how I’ve seen how they’ve learned and adapted in captivity, but pretending they’re just like people (which this movie does suggest) is the wrong way to go about this. I have no doubt that they have something that we could call emotions and they do have bonds with other whales. The movie spends a huge chunk of time talking about how the whales are sad when they get separated from their calves, and I don’t doubt that that’s the case. What the movie won’t point out though, is that an animal caring for it’s children is hardly only something that intelligent mammals do. Here’s a brief list: Birds, Crocodiles, Fish, Lizards, Octopi, Leeches. You read that right folks, the bloodsucking worms that you love to hate care for their young just like whales. There is, however, no major effort to save the humble leech, and this is because of my next point: People only give a shit about animals that are cute or majestic. I can pretty much guarantee that most of the people who suddenly felt inspired after watching Blackfish to care about animals have killed many spiders, those (mostly) harmless insects that were on this earth before you and eat all the pesky insects in your house. The difference between Tilikum and that twitching pile of legs on your wall is that Tilikum is much more friendly looking.
The one thing that spiders and killer whales have in common is that they are both animals. All animals are unpredictable and we lose touch with that. Going back to the fact that people only care about animals that are cute, we surround ourselves with “safe” animals like dogs and cats and are completely taken aback when we see animals being animals. When doing shows with any animals, things go wrong, an animal misses it’s queue, or whatever. It’s normal and it’s expected to a certain point. The problem with shows involving these whales is that because of the pure size of them, it’s a lot more dangerous to the puny human involved. You can teach a dog to sit, but you can’t teach a dog to not be a dog just like you can’t train a killer whale not to be a killer whale. People often lose touch of how brutal nature really is. People love lions but cringe when whenever they see a pride feasting on a carcass on TV. At one point the movie lists the trainer's injuries with sad music playing to try to make the view hate SeaWorld even more, but at the same time, it’s a rather frail monkey body vs a six ton carnivorous beast on it’s own turf, that’s what I would certainly expect the human body to do.
Another problem humanizing animals causes is that we assume they know the concepts like “life and death” or “this weird animal that feeds me can’t hold it’s breath as long as I can”. The point I’m getting at here is that these incidents, especially the ones not involving Tilikum, might not be acts of aggression. People have humanized these animals so much they consider them humans with fins, so we associate them having moral compasses where in reality, the know little more of humans besides “If I do this thing I get food.” They don’t hold grudges, they don’t get emotionally upset if something doesn’t go their way, none of that cartoon stuff. What makes me think that few of these incidents are legitimately aggressive is that if a whale wants to do serious damage to something, it will straight up bite and rip apart something. It won’t jump on it, it won’t drag it around for a bit, it will murder it like the carnivore it is.
Let me explain about how and why training in captivity works. Training is pretty much the act of getting something to produce the desired action. With animals in captivity, a lot of what you don’t see is to help make the care for the animal. Lots of animals are trained to go to a certain spot to eat to make sure that every animal gets the right amount of food, or if an animal is medical treatment, it will be trained to assume a certain position to make things the easiest and safest for everybody involved. The way it works now (not so much before as the movie touched on) is that if an animal does something that’s desired, it will be rewarded or given the promise of reward in the form of a whistle or clicker usually. If the animal does not perform the desired action, NOTHING HAPPENS, the trainer simple tries again and the animal will figure it out eventually.
Now as for the reason SeaWorld kept Tilikum doing shows, it’s complex, but SeaWorld is doing the best thing for the animals here. As the movie points out, animals being in captivity can get boring and trainers realize this. The trainers probably decided to alleviate this with Tilikum by having him do shows since it gets him active, thinking, and moving around. The movie also pointed out several times that Tilikum responded well to enrichment and training, so that had to do something with the decision. Some of the actions in the shows are designed to mimic natural behaviors as well. People are right, they don’t have to put on shows, but the animals would be bored and wouldn't be much better than the holding tanks at the first park.
One thing I see people complain about constantly is that SeaWorld is for entertainment only. This couldn't be farther from the truth. Yes, they make money, like any business. That money also goes towards one of the largest animal rescue and release organizations in the US that takes care of anything from flamingos to whales. They also do provide a lot of information on not only whales, but all the animals they have there. Making money is not evil if you use it for the right causes.
Now, the big question of if keeping intelligent animals in captivity is ethical or not. I worked with Octopi, animals that are more intelligent than dogs (at this point, I would totally feel more comfortable eating dog than octopi

), so I've had a chance to stew on this question a bit. I came to the ultimate conclusion of, "Ideally, we should not keep intelligent animals in captivity, but we need to." The reason I say that there is a need to keep them in captivity is to inspire and educate future generations. From personal experience, going to Sea World when I was a kid, seeing all those animals is actually what got me inspired to learn about the animals, learn how to take better of the environment, and donate my free time with the help and care of them so they can be preserved for years to come. There are many environmental issues on our hands these days, and the only way that they'll get fixed is if enough people care, and if a handful of these animals have to be taken out of their natural habitat to help with that, then it should be done. I will also say that a lot of these animals these days were not simply plucked out of the wild, that doesn't happen as much these days. A lot of these animals are rescues or have other circumstances where the can not be released in the wild again, so that does ease the ethical issue a bit.
Now lets talk about it’s supporters, the ones who claim to be environmental champions after watching the movie. Do any of you use birth control? That’s getting into natural waters and devastating fish populations because those hormones are causing a vast majority of fish in those ecosystems to be born female. How about that soap with the little beads that exfoliate your skin? Current filtration systems can’t catch those and they end up choking fish. Drink bottled water? There’s a good chance that ended up on the continent of plastic that’s currently floating in the pacific. Ever use latex balloon? Those end up in the water where animals, including the adorable sea turtle, think it’s food only to have the balloon block the intestines of the turtle causing a slow and painful death. Here’s my point: With so many threats to animals being caused by humans, in the grand scheme of thing, a handful of whales living in captivity is a rather small environmental problem on this spaceship Earth. While it’s good to a point that people are passionate about this, maybe the attention can be focused on things that hurt more animals. Though, those animals aren’t nearly as cute, so it doesn't matter.
tl;dr People only care about the whales because they're cute and Blackfish is full of crap.
