Thoughts
It's crazy to think that Europe didn't have potatoes and America didn't have horses until after Columbus.
It's also crazy to think that Columbus and the first Trans-Atlantic trade was 200 years before 1700s colonialism.
You could argue, and some have, that the introduction of potatoes from South America to Europe is what enabled the industrial revolution.
I feel like this is a little dubious, but better to have dubious numbers than no number, am I right.
