The country of Baurisia has, until now, been self-sufficient in both grain and meat  However, with growing prosperity in Baurisia has come a steadily increasing per capita consumption of meat, and it takes several pounds of grain to produce one pound of meat
Ttherefore, since per capita income in Baurisia is almost certain to rise further but increases in domestic grain production are highly unlikely, Baurisia is soon likely to become an importer of grain
It is more economical for Baurisians to import meat than grain.
