The reason for greenland's high population was the migrations of the millions of displaced peoples from across the world. With the new anarctic project, citizenship application is rushed, with applicants only needing to pass a simple greenlandish history test, promising to learn english, and an oath to the state. Preparing temporary housing for the next wave, the state quickly establishes small temporary complexes to house the new migrants. Meanwhile, more artificial farming communities are created, with farmers being spread out, to fairly distrubite farmer-grown foods. Meanwhile, the completion of the Anarctican Project is expected in the next 2 years or possibly less, depending on how the state can manage the large-scale 3d printing and manual construction.
Temporary Flag Yes, I know anarctica doesn't look like this.
