I'm reading a book about research into animal mental illness. It's mediocre but the author is doing an OK job summarizing current research and case histories.
Halfway through the book she goes on a bleeding heart rant about how zoos are inheriently immoral. She completely dismisses their educational value and role in conservation because captive animals all suffer and she thinks it's just life sacrificed for human entertainment.
It irritated me enough to set the book down. I'm wondering now how widespread is this belief that all zoos are evil? Even the annoying vegans I know don't hate the zoo.
