In 1988, Chris Packham was in the jungles of Indonesia where he photographed a young girl. Now he is back trying to find her.
The girl was from the Orang Rimba, an indigenous tribe in the Sumatran forest, whose lives have been the victim of deforestation. Thus this is not just the story of trying to find the girl in question, but also a look at how badly deforestation damages the environment.
Chris Packham: in Search of the Lost Girl is on BBC Two at 21.00.
