Freedom/Equality Shortwrite

Nelson Mandela recently passed away this last week. He was the President of South Africa and a crusader for freedom and anti-racial sentiment. He was imprisoned for his beliefs that Blacks and Whites should be equal in the eyes of the law and served a 27 year sentence in prison for, basically, treason. What can we do in our own lives to make our world a better place to live in racially and ethnically?
