Let’s suppose we give each person the same space they would have if they were lying in a coffin, except we’ll stand the coffins on their end. A medium sized coffin has an internal cross section of 520 by 290mm. That’s seven billion people, each occupying 0.15m2. You could pack them together in just 1,050km2 (260,000 acres).
They wouldn’t quite fit on the mainland of Shetland, but there would be a bit of room to spare if we spread everyone over the Isle of Wight, Isle of Man and Jersey.
