Causes and Consequences

Take a recent significant event (within the past ten years) and explain how you think a biographer, historian, or social scientist would describe the causes and consequences of the event (for example: the emergence of the European Union, the Timothy McVeigh execution, natural disasters like hurricanes, floods, or droughts). Also, explain how or if the event affected your city or community. I live in St. Louis. This should be APA and around 300 words.
