So whether we're talking about the tomato in Italy or the chili pepper and potatoes that end up in India. Could you imagine Indian food with no spice and no potatoes? It wouldn't exist. But the main idea is that these crops are going to change the old world by sustaining these populations and many would argue really leading to the Industrial Revolution, to imperialism eventually because you can't have that type of power unless you can sustain your populations and the new world through the Columbian Exchange allowed that to happen. Now on the flip side, in terms of foods that are coming across to the new world, certainly you have the orange and stuff like that, some citrus fruits, but really if you want to talk about impact, you would talk about the different weeds that they brought over and that's going to have a huge impact, especially in the Caribbean, which is going to cause a different ecological system which the people there are just not used to. So food, crops, plants, it's going to change both worlds. So there you go guys, there is the Columbian Exchange.
