I see this on the news.
I don't like to see anything caged, no matter that the cage cost millions. That caging them may preserve them from humans seems, well, not a good solution to an issue.
I recall, decades ago, seeing the first gorilla at Taronga Park zoo.
His arrival and his display was greeted with noisy pride and acclaim.
He was in a small enclosure. He sat, legs crossed, leaning on his fist, and looked like an (obscene) middle aged CEO. He stared back at us with contempt, rage, extreme boredom and deep, deep despair.
