The island chain of Indonesia is home to more active volcanoes than any other country in the world. Yet somehow, instead of posing a threat – this volcanic activity is a source of life. The 130 volcanoes have transformed the islands from isolated mountains of hot lava, to lush jungle homes. For millions of years rich fertile ash has supported pristine rainforests, allowing life to flourish. Indonesia’s 17,000 islands house more mammals than anywhere else in the world. Those residents have uniquely adapted to the specific demands of life in the furnace. From birds that lay their eggs in volcanic ash, to bears that can climb the world’s tallest trees and bearded pigs that wallow in Borneo’s Mud Volcano.
