They emit huge amounts of poison gas and ash, yet provided some of the most fertile land on Earth. In the Globe Trekker Special, the travelers, explore the world's most spectacular volcanoes, travelling from the heart of Europe, across the Atlantic and Caribbean, to the deadly Pacific Ring of Fire.
