Series in which intrepid presenter Kate Humble follows the ancient frankincense trade route of Arabia across the amazing modern world of the Middle East. Kate s journey along the 2,000-mile trail that first connected the Arab world with the West takes her on a quest that s steeped in history, searing with desert heat, and full of characters and adventure. For 3,000 years before the birth of Christ, frankincense was more valuable than gold. Its sweet smelling aromatic smoke was treasured by Pharaohs and Caesars, and their insatiable demand for frankincense created a trade route from the southern coast of Oman to the Holy Lands. Vast camel caravans carried thousands of tons of frankincense over tribal lands constituting the modern-day Middle East. Following the trail, Kate finds modernity coexisting with ancient traditions as she discovers what it means to be a Western woman in Arabia.

The impending disappearance of salmon will have profound effects on the world. Uncover the remarkable and vital role this fragile fish plays in sustaining richly diverse ecosystems.

The impending disappearance of salmon will have profound effects on the world. Uncover the remarkable and vital role this fragile fish plays in sustaining richly diverse ecosystems.

This film will investigate the parallel stories of collapsing Pacific salmon populations and how biologists and engineers have become instruments in audacious experiments to replicate every stage of the fish s life cycle. Each of our desperate efforts to save salmon has involved replacing their natural cycle of reproduction and death with a radically manipulated life history. Our once great runs of salmon are now conceived in laboratories, raised in tanks, driven in trucks, and farmed in pens. Here we go beyond the ongoing debate over how to save an endangered species. In its exposure of a wildly creative, hopelessly complex, and stunningly expensive approach to managing salmon, the film reveals one of the most ambitious plans ever conceived for taking the reins of the planet.

Jamie Oliver continues his cookery demonstrations by preparing crispy salmon with rice, baby courgette salad guacamole and berry spritzer.

Part 6: The Surprise Salmon
In Alaska, the fresh water that feeds the rivers is snowmelt from North America’s highest mountains and most active volcanoes. Time and again, they erupt and poison the rivers. Scientists have only just begun to piece together what might have happened nearly 2,000 years ago, when one race of salmon faced the death of their natal river and were forced back to the open ocean - on an extraordinary adventure...
