Ted-Ed si occupa di un tema ticinese per parlarci dell’eccezionale stato di stratificazione permanente delle acque. Un lago dove l’acqua non si mescola con l’acqua? Il lago Cadagno, un piccolo specchio d’acqua in Leventina, è uno dei pochi esempi al mondo di lago meromittico: due strati d’acqua sovrapposti e immiscibili che creano un ambiente unico e che, in un certo senso, sembra provenire da un altro tempo o mondo.
