But few actually have the opportunity to travel halfway around the globe in pursuit of their objectives.
Tomas Murawski is one of the few.
In January, while other students were waiting in line for books and meal plans, the junior journalism major was en route to Iraq to document the effects of United Nations sanctions that limit international trade and travel with the country.
Iraq is a concern for humanitarians like Murawski because the nation's death rate has multiplied during the decade since the Persian Gulf War.
"Basically, nothing goes in or out of the country," he said. "This leads to death by malnutrition and illnesses that go untreated."
Murawski has been involved in social issues since his sophomore year at UNC, including working for Students United for a Responsible Global Environment and the Campaign to End the Death Penalty and hosting a show on WXYC called "Northern Hemisphere Live."
Murawski first became interested in the conditions of Iraq last semester when British Ambassador Sir Christopher Meyer visited the University. "Meyer is really pro-sanction," Murawski said. "I printed up protest fliers, and I actually got into a spat with him. I've been really active on the issue since then."
Soon after, Murawski discovered the trip to Iraq sponsored by Conscience International, an organization that leads social and political activists to countries in Africa and the Middle East.
With funds from SURGE and the University along with money from his own pocket, Murawski joined the first American delegation unaffiliated with the government to fly into Iraq.
