We are writing to some alumni of the University of Cambridge Media and Environment seminars gathering ideas for the BBC's coverage of the Rio+10 Earth Summit in a year's time. Before the Rio summit, the BBC held the One World festival, which included some memorable broadcasting - particularly a feature drama on refugees. Some broadcasting is already in the pipeline that will relate to the themes of Rio+ 10, but this is an open opportunity for you to put forward ideas that will be collated and circulated amongst relevant BBC decision-makers.
* What should the BBC be doing this time in terms of news, current affairs, drama, documentaries, game shows, music etc? * How can the BBC convey the theme of sustainable development to viewers and listeners who have probably seen all the issues raised before? * Is there any scope for a global broadcasting initiative? * What are the strongest themes and specific issues that should appear in the media in the months and years following the conference?
