I am a biologist. I can say that this is nothing like the food chain. In the wild, predators do not sit around to be fed. They hunt, and the ability to kill quickly (before the prey escapes) is an invaluable skill that they cannot survive without. This is not educational, this is teaching children that animals are here to be tortured.
But then again, China doesn't really value human life either.
Remember the old version of the one child per couple law? If a couple had more than one kid, the second would be killed? Sometimes if the child was a girl it would be killed anyway, since a male child was preferable. Nowadays, I think families pay a heavy tax to have more kids, but still.
I'm not a mother, I'm still too young to want kids or a husband. But can you imagine having a baby and then your husband takes it away from you and kills it because it is a girl? without even letting you hold it, or see it? Or your parents having a baby and killing your little brother or sister because it's against the law to have more than one kid?
