Some very funny quotes I pulled from the first article:
"Orcas are used to swimming around 100 miles per day, but in SeaWorld there is barely enough room for the Orca’s to move, let alone swim."
Oh yeah, the tanks are so tiny, the orcas can't even move...
"So much inbreeding has also occurred at SeaWorld, which is of course not natural in the wild and has caused many health concerns."
To my knowledge, the only inbred calf born at SeaWorld is 0.1 Nalani born in 2006 to Taku and Katina, a son and mother pair. Also, there is proof that wild orcas do occasionally inbreed.
"Orca’s in the wild live nearly as long as humans however, in captivity they are lucky if they will live over 10 years of age."
Of the 19 orcas in SeaWorld care, only two (Makani and Kamea) are under 10, the oldest in their care (Corky) is 50+ and there are several in their late 20s to mid 40s.
Let's wrap up this conversation here, I really don't want to get back into this discussion on here, there are tons of threads on this topic already so please use the search tool in the top right of the page and look for them. SeaWorld is trying their best to understand orca needs and is doing their best to fulfill these needs so people need to stop putting all their faith and trust into organizations like PETA and stop bashing SeaWorld so much without doing any reading of their own.
