for as great as he was for skiing and BASE....im not sure he "Changed the world"
he definitely changed the sport. a few sports. he definitely was a great human being who influenced possibly hundreds of thousands. but his impact on humanity as a whole was minute at best and borderline universally insignificant.
OP, if you do your paper on a skier you deserve a bad grade for poor subject choice.
