What are the issues?

Before I began my two sections of 51-276: 'Examining Sustainability in the Gulf' last week, I gave the students a questionnaire, asking basic details about their background, expectations, and whatnot. However I also asked them to list what they perceive as the top 3 issues/problems/challenges facing 1) the world? 2) the region (or their home county)? 3) Qatar? 4) themselves? It was enlightening to see the answers and gives me hope that their interest will be sustained in the course.

What are the 3 biggest issues/problems/challenges facing...
