The Columbian Exchange

I'm sitting here eating Indian food (goat in a tomato curry sauce with rice and naan) and typing up a study guide about the Columbian Exchange. I don't know if I'd call it ironic, but definitely appropriate (tomatoes originated in S. America, if you weren't aware, and were brought by the Spanish to the Philippines, other ports in Asia, and of course Europe). Maybe one of the best parts of teaching World History is being consistently reminded of the factors/themes that have shaped our world.
