Cassava: The Lifesaving Crop That Could Also Kill You
It’s white, starchy, and grows like a weed in poor soil. In many parts of the world, it’s not just food—it’s a lifeline. But behind this humble root’s reliability lies a little-known danger. Cassava, while feeding millions, silently puts lives at risk. How is that possible? And why do people still rely on it?
