I think Ryan Hreljac is a great example of the global citizen.  He is a Canadian who lives in Ontario. He raised many money for the people who don’t have clean water. He help them to chisel the well, and then his family, friends help him to founded the “Ryan’s Well Foundation”. He already raised 1,500,000 CAD as of April,2007. He helped more than 500,000 people in Africa, Asia, South America. I think he make great contributions to the world, he is a great global citizen.
