It would probably end up being one company per building, however, so families would either have a single working adult or two adults working in the same company, if one ignores the restaurants and such. It also isn’t too deep; it’s just taller than the Leaning Tower of Pisa (56.7m) so if there is an emergency diving won’t be ruled out as an exit strategy (although it’s still a little iffy). There are some obvious problems with the idea but it is good to see people attempting to address the problems caused by climate change. ***
