If everyone inhabited a strip of the earth 15 degrees wide stretching from the Arctic to Antarctica (I’d suggest Europe/Africa to maximise land; N and S America are deceptively not on top of one another latitudinally), then we’d all be in the same time zone, and no other time zones would be of interest.
Here’s the maths to support the argument:
- World radius: 6,378km
- Surface area: 511m sq km
- Surface area in 15 degrees: 21m sq km
- Percent of land in 15 degrees: 60% (wet finger based on 20-35 degrees east)
- Surface area of land in 15 degrees: 12.8m sq km
- Population density required to house the world’s 6bn people: 469 people per sq km. (Current population density of the UK: 383 people per sq km.)
It’s quite a big project to make this happen, but I think I’ve presented enough of a business case for someone to start running with this. High-level plan anyone?
