Analysing Mercosur and its impacts on trade across the population of latin america or the world

I need to write a paper on an interdisciplinary studies course concerning food. My paper has to be about the aspects of trade, imports or exports. Therefore, I want to focus on a free-trade organization among some Latin American countries known as Mercosur. I need to analyze and educate readers about how they do their trading patterns. Also, if there is a possibility to focus on some particular foods that are being imported or exported between Brazil and Argentina and how the economic crisis affected the trade in the past, that would be great. Bottomline, since this interdisciplinary course has to focus on foods, I want to talk about trade, so I chose Mercosur as an example to understand how they distribute goods across the globe. Scholarly articles has to be a must and bibliography must also be included.
