Gone Fishin'
Inspired by a B2 thread mentioned in a post 1900 pod, what could be the maximum population of the UK in the years 1700 & 1800?, with regards to land use and feeding her peoples?

Could it be double, triple or quadruple etc?

Cheers filers
 
If North America is not there as a population release valve, it'd certainly be quite a bit larger. There were 2.5 million Americans upon the independence of the United States, and the majority were of British ancestry.
