Logging dilemma

There's big money to be made from tropical timber. A large tree in the forests of Papua New Guinea can fetch as much as £1,000 back in the UK. The owners of the land are often small tribes that live throughout the forest, and have to decide whether to keep their land and trees intact, or sell them to the loggers. But they rarely see much of the profit, receiving only about £8 per tree. George McGavin points out how keeping the forests intact will help to combat global climate change and save between 60 and 80% of all the world's species.
