A 'pea-souper' is a thick, dense fog, usually yellowish or greenish in color. π€’ Itβs called a 'pea-souper' because it resembles thick pea soup. These fogs were common in London and other industrial cities, especially during the 19th and early 20th centuries. They were caused by heavy air pollution from burning coal. Pea-soupers made it difficult to see, causing traffic problems and health issues. Nowadays, they are less common due to cleaner air regulations, but the term remains a vivid reminder of industrial pollution. Imagine trying to navigate through a dense, choking cloud!
