Lying at the heart of Indonesia in South-East Asia is an exotic island of lush jungle, smouldering volcanoes, black beaches and coral gardens that is under threat from human rapacity.

Sulawesi was created by the collision of the Asian and Australasian land masses. Here strange creatures have evolved that exist nowhere else on earth, from crested monkeys, giant snakes, birds that incubate their eggs with the heat of volcanoes, to bizarre pigs whose twisted tusks cut into their cheeks - many of them caught on camera for the first time by Emmy award-winning film-maker
Andrea Florence. But the precarious balance of nature is being threatened by nature's most powerful enemy - the human race. Narrated by Ian Holm.

Continuing the occasional series that analyses topical issues, The Big Picture asks whether Britain can survive as a nation and whether it matters if it doesn't. The Prime Minister has described Scottish devolution as "the most dangerous proposition to be put before the British electorate".
Others see European integration and the development of a single currency as threats to the nation. Some regard developments in Northern Ireland as undermining the union. Many believe that Britain's constitution needs updating. Whatever else they dispute, most people agree the status quo is unlikely to survive. Peter Snow reports, followed by a studio discussion.
