Cloning Ethics

Hello, I'm a university student. Therefore my opinion is not good. Anyway, I think human should be born naturaly. Good people, bad people, tall, small, fat, black, white,,,,, they are humanbeings. These are wonderful. Many kind of people lead many kind of lifes. Good!! it's a life. But I don't know about animals. What they are thinking? Do they have mind? Do they feel happiness? I don't know. So, I don't know about animals. I wish they speak languagaes!
