Shut up zoos, not animals

You may think that visiting a zoo is harmless fun, but you’re wrong because zoos are just prisons for animals. The difference is that prisoners get out after a few years!  Animals in cages look bored and are boring to look at. After all, we all know what an elephant looks like, we’ve seen them on TV. So why make animals suffer by shutting them up for our entertainment? Shut up zoos instead.
