"In a few days time, the leaders of the G8 nations will meet in Scotland. They will face perhaps the most critical question that our world has had to face. How do we remove the face of poverty from our world? So much of our common future will depend on the actions and plans of these leaders. They have a historical opportunity to open the door to hope and the possibility of a better future for all. History and the generations to come will judge our leaders by the decisions they make in the coming weeks." Nelson Mandela, former South African president speaking at the Johannesburg Live 8 concert on Sunday.
