The Big Island of Hawaii is home to the world's most active volcano, Mount Kilauea. Since 1992, it has been in a state of constant eruption, spitting out clouds of poisonous sulphuric gases from the soil. Here, the landscape is denuded of plant life, devoid of water and few animals are ever seen. Beneath the unstable surface lies a river of molten rock boiling at temperatures above 2,000 degrees F. Surrounding this volcanic landscape is a dense rain forest, which offers environmental relief but features dangers of its own. To highlight the skills necessary to survive, Bear abseils from a helicopter into this treacherous expanse and demonstrates how to create a gas mask, escape from a moving lava flow, find water in a lava tube and get honey from a bee's nest.
