London, December 1952. A thick toxic smog blankets the city, reducing visibility to almost zero. Coal smoke, trapped by cold air, turns the streets into a choking maze. Hospitals overflow. Public transport halts. Thousands lose their lives in what becomes known as the Great Smog — one of the deadliest environmental disasters in modern history. This tragedy reshaped air pollution laws worldwide and changed how nations protect the air we breathe. #GreatSmog #london #historytok #educational #docume
