During the past 500 years or so, human activities have released mercury from its relatively stable and water - insoluble form (cinnabar) in rocks and soil through mining, fossil fuel combustion, and other activities, and so have increased the portion of mercury that is actively cycling through the atmosphere, surface waters, plants, and animals as it changes chemical and physical form.

The automobile had been invented and entered mass production in the early 1900s, but just as the internal combustion engine started to prevail over electric cars at that time and mass production took hold with Ford's Model T bringing some cars and trucks into upper middle class households and into use by businesses and farms, the Great Depression and World War II dramatically reduced private personal consumption, so for the two decades from about 1929 until the several years after World War II that it took to convert factories from war production to civilian peacetime production, the automobile industry's private sector sales were greatly suppressed, domestic civilian road and bridge construction came to a near halt during World War II as government funds were diverted to the war effort, and domestic oil consumption was likewise suppressed.
