London Smog

The London Smog, particularly the Great Smog of 1952, was a severe air pollution event caused by a combination of cold weather, high pressure, and widespread burning of coal for heating. This created a thick, smoky fog filled with pollutants like sulfur dioxide and smoke particles, which trapped in the city's air. The result was a dense, gray haze that severely affected visibility and health, leading to respiratory problems and thousands of deaths. It highlighted the dangers of air pollution and prompted major environmental and public health reforms in the UK.
