8 of History’s Oddest Conspiracy Theories

2. Chemtrails

All of us in the modern world are well-accustomed to seeing the sky streaked with those puffy-looking white lines that high-flying jet aircraft leave behind. To most they are known simply as contrails, but a number of people believe there is more to the story than simply flying from Atlanta to Denver. Although there is some disagreement about exactly what these planes are said to be spraying, those who believe in chemtrails are convinced that whoever is doing it is up to no good. Some of the more common explanations among conspiracy theorists is that the government is spraying materials into the atmosphere in order to influence the weather. Others believe that chemtrails contain tiny objects like “nano fibers” that can wind up inside our bodies where they cause serious health problems and contribute to a significant reduction in the human population.
