In episodes 3 and 4, a seemingly simple ingredient becomes the invisible force that has shaped civilizations, fueled exploration, and quietly dictated the fate of empires. From ancient trade routes to modern industry, salt emerges not just as a seasoning, but as a powerful driver of human history and survival. At the same time, the story shifts to something far more familiar yet equally unsettling: the global dominance of a single type of banana. What appears to be abundance hides a fragile system built on uniformity, where one disease could wipe out a staple food relied upon by millions. As the journey unfolds, the narrative exposes the hidden cost of convenience and monoculture, revealing how the loss of biodiversity is not a distant ecological concern but an immediate threat to our food security and future. With striking connections between past and present, these episodes invite you to rethink what you eat, where it comes from, and how something as ordinary as salt or a banana could hold the key to understanding the balance—and imbalance—of our world.
During 1959-1961 both the Americans and Soviets are planning manned space flight, and we see both sides preparing to do so with the development of the Vostok programme (Russia) and Project Mercury (USA). After difficulties and failures on both sides, the Soviets succeed in putting Yuri Gagarin into space first, with the Americans putting Alan Shepard up shortly afterwards.
