This is bullshit. Seem happy enough? What, do the dolphins seem happy enough to you because they're always smiling? You don't know a goddamn thing about the welfare of these animals.SeaWorld here on the Gold Coast, Australia are usually the first responders to incidents of whales and dolphins getting injured or stuck in nets off our shores. They do a good job, and their animals seem happy enough. I know a couple of people who work there, and they consider the animals they care for as their family.
Helping injured whales and dolphins is commendable of course, but I can guarantee that not a single dolphin or orca is happy to live in a tiny pool.
