Beasts and human are living in this world together, it means they compete with each other. In order to live good lives, human kill beasts for food, beasts fight for their lives, but they don't have clever brains like human, so been killed is their fate. They don't give up their lives without any fight. They do fight. Sometimes their fight is horrible. Have you ever seen termite damage? Awful! This is the fight from termite. You should care about it.
One thing I am thinking is, can't beasts and we human live together in peace? We don't kill them, and they don't damage us. What a good thing! But I know it won't happen.
