I wrote my first short story when I was 10. It was about a planet called Rizak that was facing ecological collapse. Rizakian scientists had discovered a path away from inevitable destruction, but it required everyone on the planet working closely together and no small measure of personal sacrifice. Rizakian politicians and religious leaders hated the plan because, if everyone worked directly to fix the problem, politicians and religious leaders would no longer be needed. Rizakian business leaders hated the plan because it was expensive and meant no one would have time or money left to buy the things they were selling. So, everybody died.
I grew up in Oak Ridge, Tennessee (site of the WWII Manhattan Project) during the Reagan administration. At the time, I felt pretty certain I would die by sudden nuclear annihilation. Funny how, despite the preoccupations of the conscious mind, the unconscious mind finds the more plausible story.
