Buddhist pursuit of peace questions

I've been researching about Buddhism and their pursuit for peace and i have some questions. - Do you believe that Buddhism has shaped society today. If so how? - How has Buddhism influenced your life? - Where in Buddhism does it say that you have to live your life in peace? - Do you believe that a pursuit of peace is necessary in today's society? - As a Buddhist, how does a pursuit of peace begin? (How do you pursue it, what does a "pursuit" of peace entail and when does your pursuit end?) - Do you believe that all people should follow a life of peace? - As a Buddhist, do you think that Buddhism has the idea of changing the world? - If Buddhism values finding peace within yourself, how is each person finding peace among themselves going to help change the world? Thank you.
