This is a vague question. Are we including humans because we are animals and that is not ok. But peoples want to see rear animals in zoos can benefit them because it gives them a safe place in which to live. This can help endangered animals.
Oh what would YOU feel if YOU are an animal, locked in cage and unable to do what you were MEANT to do? If my friend Broke was here, she'd DEFINITELY say no, she is a vegetarian and gave up eating her favorite ribs just because she likes animals and wants to protect them, what about putting you in a cage just for others to put you on photos.
