The World Without Us 15 October 2014 Update

I'm on page 180/353. If humans were to disappear without warning, then North America would be destroyed. The nuclear powered factories would eventually melt down. The first initial explosion would start a chain reaction. The combined powers of all these nuclear meltdowns would put North America into a mini-nuclear winter. If humans had a small warning that they were about to disappear, then the workers at these factories could take the necessary precautions to prevent the mini-nuclear winter.
