McGavin heads the other team and goes to Tavurvur, an active volcano on New Britain. He sees a brahminy kite hunting over the grey ash-covered landscape, and finds an adult rhinoceros beetle and one of the larva in a tree stump. He sees megapode birds digging in the warm ash to bury eggs, and when they have finished he uncovers and reburies a large oval egg. He finds scavenger crabs before spectacular volcanic activity forces the team to evacuate the area. After this, McGavin goes to New Guinea and a helicopter takes him to the rim of Mount Bosavi. He reports on the dangers of climate warming and of humans to the wildlife as he watches an ornate fruit-dove. He sets up a night-light which attracts hundreds of moths, and he suspects many are not known to science. As the helicopter arrives to collect him from the summit, he wonders if the rainforest and its biodiversity will be destroyed.
