What would happen If people never cooperated ..

I thinks if everyone didnt cooperate everything would be chaos, noone would follow rules. You couldn't drive or walk or talk. The whole world would prolly be in prison or something because you have to cooperate to do anything. Classes would be horrible because you couldnt even  do anything. It wouldn't be a very fun place to live at all. People would have hurt feelings all the time. and people would fight alot, making it hard to even live I thinks. What do i think cooperation means, I think it means working together to co exist following rules, and helping each other.
