Explanation:

[STC001598] There’s a good reason London was given the moniker “The Big Smoke” (or “The Old Smoke”). It may not appear that smokey right now. In the 19th century, the British capital was home to ‘pea souper’ fogs that choked the city in gray and black — a result of air pollution, principally caused by burning coal as fuel. The moniker “Big Smoke” first occurs in a slang lexicon from 1874. Up until the implementation of the 1956 Clean Air Act, the city’s smoky conditions remained through the 1950s. In the aftermath, only “smokeless fuels” were permitted to be burned in towns and cities, leaving a much fresher London to look for new names.
