Aloha – Okay Option 1 was an Asteroid Armageddon, next let’s take a look at extinction through volcanic activity. Within human-kind’s history we’ve already had a couple of unsettling events. Volcanic activity resulted in a mini-ice age in Europe just a few centuries ago. Yellowstone has the potential of reeking havoc with all of North America, and probably generating a more substantial ice age for other parts of the world. It has a major eruption approximately every 600,000 years, and we are overdue. Still in perspective, the odds of one occurring in any given hundred hear period is around 6,000:1. That is pretty high if you compare it to the 11 million:1 odds of being killed in a plane crash. Still the odds are such that you are more likely to die in a car crash sometime in an average life span 470:1. So a geyser view cabin in Yellowstone is still a better bet than driving to work every day.
