b. Millions of coal fires and stagnant air caused toxic fumes to build up in the air. The main cause of the coal fires, which burned at plants across England, was a weather pattern that produced cooler weather and air that did not circulate. Citizens used more heat and so more coal was burned. The post-war coal was not great quality and thereby included many toxins. The weather pattern created fog, which after it dispersed, left toxins and acid droplets to fall on the people.
