What if I told you that a single species of fish rewired global politics, funded revolutions, and ultimately taught us the limits of human ambition? The Atlantic cod-an unremarkable-looking creature with a protruding jaw and insatiable appetite-has shaped more of human history than most world leaders. For nearly five centuries, this fish powered empires, sparked wars, and fed millions. Then, in a single generation, we wiped it out. This isn't just an environmental cautionary tale. It's the story of how a humble fish became the thread connecting medieval exploration, American independence, and our modern reckoning with nature's limits.
