One of the saddest things about the destruction of the west Papuan rainforests is that everytime some scientist goes there (eg Flannery), they discover huge number of hithero unknown species of animals, ranging from insects, dozens of frogs through reptiles, birds and seeminly everytime, a new species of possum, cuscus or tree kangaroo. The whole island is nowhere near being known by zoologists, who knows how many other species are disapearing as the loggers move in.
