It’s in your kitchen, on your table, and in your blood—but salt is far more than a seasoning. It is a geological titan that has the power to trigger catastrophic climate change and dictate the rise and fall of empires. In this documentary, we trace the 190-million-year journey of salt. We travel from the frozen landscapes of the Ice Age—where salt was the secret to hunter-gatherer survival—to Ancient Egypt, where it became a weapon against famine and a key to the afterlife. Discover how the "White Gold" of the Phoenicians created the first global trade networks and how a salty "ocean conveyor belt" governs the very air we breathe today.
