Why are so many bad things happening at SeaWorld?

I don't get it! I've seen a like a million videos of things happening to people at SeaWorld because of the animals or some person has a done something completely stupid. I saw this one of a kid falling off a ride, now that was a cause of carelessness. But I know SeaWorld isn't' a bad place, I just think they need to be more careful. And I know that locking up animals and putting them in cages or tanks is a bad thing. I know. But sometimes it saves their lives because it's not able to survive in the wild. Like with the manatees. People are at fault for that! Stupid people driving their stupid boats and hurting the manatees. What did the manatees ever do them? Let's see... NOTHING! I just think that sometime's it's the not the animals fault. It's the person's fault. And I just think that people need to be more careful when around animals that could easily hurt or kill them.
