If we lived in a world where everyone loved each other as much as themselves...

           Life would be so much different, you couldn't imagine what it would be like. There would be almost to no contention. There would be world peace and you could understand each other. To answer the question, ''What would it be like to live in such a world'': it would be beyond comprehending. The world would be in an amazing state, there would be no murders any harm to anybody. To answer the other question, ''How would families and communities be changed''. As I said nobody would be harmed by any other person ever again.
