No one said animal's life is more precious than human's. However, for those people give no regard of a life of an animal, they often don't care about other humans as well and often they become criminals later in life. This is the reason why animal cruelty is serious crime in US.
In China, there are too many people just don't care about anything and anyone other than themselves. I am sure everyone know what it is like to live in such a society.
