The book's description provides an excellent summary:
"In 'Beneath the Surface,' Hargrove paints a compelling portrait of these highly intelligent and social creatures, including his favorite whales Takara and her mother Kasatka, two of the most dominant orcas in SeaWorld. And he includes vibrant descriptions of the lives of orcas in the wild, contrasting their freedom in the ocean with their lives in SeaWorld. Hargrove's journey is one that humanity has just begun to take - toward the realization that the relationship between the human and animal worlds must be radically rethought."
I really enjoyed the entire book, and I found a lot of food for thought in Chapter 12 called "A Vision for the Future." Hargrove begins: "The prospect of a SeaWorld in financial decline does not fill me with glee. The company may be motivated by greed and it may have exploited both orcas and trainers, but SeaWorld is, paradoxically, the best hope for the 30 killer whales that it owns." Clearly, the whales can't be released into the wild. And, of course, clearly they shouldn't breed. SeaWorld has tampered with and changed their fertility cycles, the animals are clearly socially dysfunctional, and they are imprinted on humans. It would be a recipe for disaster if any were released into the wild.
