By assigning value to things we devalue ourselves.  By making a rock priceless now people are less than.  We care more about the rock then for ourselves.  This is the necessity of war when people are not sharing.  When sharing nothing has value only people.  When invisible borders of history no longer plague your mind preventing clarity to the existence and cohenesion necessary for a species survival.  Do we behave like animals or civilize and become human beings natural born citizens of earth doing our duty to care for all.  Life is the only thing of value and caring families would ensure each and every single being was offered the best we are capable.   This is what kind people naturally do without need of praise or reward.  World Peace waits only for peaceful people.  You are not yet one of them.
