8. How did the “Great Fog of 1952” happen in London?
It was a serious and early event of environmental pollution, occurred in London between December 5 and 9, 1952. The unprecedented phenomenon covered with a dense smoke that darkened the entire city. It was considered one of the worst environmental impacts until then, caused by the uncontrolled growth of the burning of fossil fuels in industry and transport. It is believed that the phenomenon caused the death of 12,000 people and left another 100,000 sick.
The large number of victims was an alert that gave an important boost to environmental movements and led to great concern about air pollution. From then on, measures were taken limiting the use of fossil fuels in the industry. In 1956, the “Clean Air Act” was passed to restrict air pollution.
