And it's also worth noting that corn, while it may not feature prominently in European diets, has been the central source of food for animals in Europe for centuries. And in fact, that's still the case. In 2005, 58% of the corn grown in America went to animal feed, is the kind of thing you learn when you live in Indiana. Alright, so last but not least, the Columbian Exchange involved the transfer of lots of people. Again, in the early stages, this movement was mostly one-way, with Europeans and Africans, the Africans usually against their will, making their way to the Americas. So the Columbian Exchange led to the repopulation of the New World following the disease devastation of the initial encounter, and better nutrition allowed the population of the Old World to grow, which in turn placed population pressure on Eurasia, which led to more people coming to the Americas. In the process, the world's human inhabitants became more genetically and ethnically interconnected, but it also led to the horrors of Atlantic slavery, which we'll be discussing next week.
