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. Now there are tons of other examples, why don't you leave some of them down in the comments below, but we certainly hope that you have the basic skinny when it comes to animal, plants and diseases and how they rocked two worlds. And make sure that you rock my world by going down and subscribing below and check out the video arsenal, we have hundreds and hundreds and hundreds of videos. Now I'm going to say it because I say it at the end of every lecture because I believe with all my heart, where tension goes, energy flows.
