Talk:Columbian Exchange

The Eastern and Western Hemispheres can't really apply here. Technically they refer to the two halves of the globe to the east and west of the Prime Meridian that runs through Greenwich, east London, England. That would mean that nearly all of London, most of Britain, Ireland, most of Spain, that great bulge of western Africa, are in the same (western) hemisphere as the Americas.
