What are the 3 most important issues that you've learned about during the course?

Throughout the entire course, I feel as though I've had my eyes opened to many very important issues.  As a keen finance student, I must place high importance in the European debt crisis.  Though I include the debt crisis in my top three, I feel as though the AIC and human trafficking have impacted me a lot this year and thus can be seen in my top three important issues taught this year.
As mentioned in my most recent blog post, I outlined how the European debt crisis can affect the entire global economy in a very negative way.  Learning more about this issue has opened my eyes about more of the details of what is happening in Europe both through learning in class and by solidifying my knowledge of the topic by teaching my peers what I know about the issue.  Through helping other people understand how bonds work and what a default may cause, I managed to use my knowledge of the EU to have a very successful Model UN conference in New York and bring my expertise to be seen as worthy to bring my views up in the General Assembly in front of over 2500 people.
The AIC took up a very long stretch of the class and is therefore one of my top three choices.  Throughout the months that the simulation was going on for, I learned a lot about the religious conflicts over land between the Arabs and Israelis as well as a high amount of information on Saudi Arabia's economy and ties to the US.
Finally, the recent presentations on human trafficking throughout Europe and Canada created an emotional response with me.  Knowing that such horrible things are happening to young women, even girls, is a disgusting issue that needs to be addressed as soon as possible. Though I don't really know how the governments can really take a lot of action on this problem without violating some human rights, I thing it is imperative for the governments of North America and Europe to either individually or collectively take a stand again these misogynistic actions.
