That's fine that SeaWorld has contributed to our Earth in so many ways, it's much appreciated, but they need to stop capturing and breeding these animals for the entertainment of humans now. They have "learned" enough. They don't belong in concrete tanks. They can still contribute to our Earth without holding these beautiful creatures captive. They should take some of their money and contribute to our Earth by creating a sanctuary for these animals so that they can live out their lives in their natural habitat but still be under the watchful eye of caring conservation experts.
If getting on a boat to view these animals isn't an option for you, turn on the Discovery Channel or open a book. Why do average citizens feel that their need to see these animals up close and personal is so much more important than the health and overall happiness of the animals?
If we were to keep in line with this way of thinking, "that they've contributed in so many ways, what's the big deal if they abuse a few animals", it would be the same as saying that a teacher contributes to our children and their future by teaching them and preparing them for the world beyond. But if that same teacher kidnaps a few children and holds them hostage for the entertainment of paying customers, it's ok because they are helping the other children, ykim?
It's time to let these creatures live peaceful, stable and more happy lives, in their natural habitat. We have "learned" enough about them from within the confines of a concrete tank. IMO.
