What would happen if people never co-operated? Why do you think it is important to co-operate?

If people never co-operated the world would be totally different than it is now. People would be fighting each other all the time and never able to work together to accomplish anything. We'd never be able to live in houses any bigger than we could make ourselves. We'd have to do our own hunting and growing. It's sort of like with wolves. Lone wolves almost never survive, but in a pack they can protect each other and work together on a hunt and building a den. When one of the wolves is sick they can work together to take care of them and the entire wolf pack works together to help protect and teach and raise the young. Therefore it's important to co-operate because when you work together with one another you can accomplish a lot more and everyone benefits.
