The Rio Earth Summit 1992

It's the last day of the Earth Summit in Rio de Janeiro. The agenda has been finalised, the convention signed, or not signed as the case may be, and the world leaders have had their say. Presidents, prime ministers and kings have been speaking solidly now back-to back for seven minutes each for two days. There have been some familiar themes - the history of the moment, the impending ecological crisis and the unacceptable gap between rich and poor. Our leaders expressed their new resolve to address the problems and acknowledged that while problems haven't been solved in Rio, the first step along the way. Reporter, Liz Jackson gathered four delegates to discuss the summit.
