The Great Smog of London and Air Pollution

The video explores the history of smog in London, starting from the 1200s when coal replaced wood as the primary heating source, leading to increased air pollution. The Industrial Revolution exacerbated the problem, culminating in the Great Smog of 1952, which caused thousands of deaths. This event prompted legislative action, such as the Clean Air Act, to control pollution. Despite improvements, air quality issues persist in London and other industrial cities worldwide. The video highlights the importance of regulating emissions to prevent air pollution and protect public health.
