Animals are deprived of everything that is natural and important to them. They become bored and lonely, that is why most animals inside the zoo suffer from "zoochosis". Bar biting, self-mutalation, circling, pacing, vomitting and swaying are just some of the things that happen to them when held captive.
Just because WE have freedom, does not mean that we have to take away THEIRS. Just imagine if people were behind bars and used for entertainment. Imagine yourself caged forever, being watched your whole life and not even having the chance to see the world. Would you survive? Think about it.
I am a Filipina, and I am not afraid to go against this. It is just unbelievable.
