Rebuttal to Mark Twain

Mark Twain says humans are below the common animal. But how can a man be below a animal when animal can just do simple things to survive. Humans can do that too but we can also help others unlike some animals. He states that hunting was a sport, but I say how is it sport when you hunting for food. Animals also hunt for food and we can't really know if it is for sport or just what it really is because we can only imagine.
