I don't know how the world is going to end! But if you ask me I would say that the world is going to end because people don't listen to each other. people don't want to listen or they don't let each other finish what they want to say. Probably the world is going to go down because of misunderstandings. I don't really know. So people start listening to each other and please try to understand each other. This will help. we want to be understood so we have to try understanding others.
