What if your state or country had to rebuild after…
Tomorrow, the entirety of humanity disappears without a trace from the earth except for the area in which you currently reside. It therefore falls to the people of your State (or country, for non Americans) to rebuild civilization.
Would you have a sustainable population?
Could your population survive without the outside trade and support that it is currently used to?
Assuming you have some authority in this new world order, what special decisions and actions would you take to have the best chance for success?
How long would it take for your new humanity to repopulate most of the planet (at least five billion people populating all the continents besides Antarctica) and what would the resulting culture(s) be like?
Easy Mode: All of the world is identical to how it is right now as far as climate goes. Cities and infrastructure are completely intact but will degrade at the natural pace without maintenance.
Medium Difficulty: All the world excepting your area is in a ravaged and highly degraded state. There are large swathes of nuclear contamination. Most of what humanity had built is crumbling and in disrepair.
Hard Mode: All of the world has gone fully to post-apocalyptic hell. You wake up to find mutant variations of your local fauna trying to kill you. This is you and your fellow last remnants of humanity’s new normal.
Can you make it through easy mode? Hard? None?
