About 1.1 billion people in the world survive on just $1 a day.

It's a fact that economics students Chris Temple and Zach Ingrasci couldn't get out of their heads.

"What can I do? That's the hardest part about it ... there is no one answer," says Temple. "[The U.S.] has poured $2.5 trillion dollars into international development trying to end poverty and a lot of times it just made things worse."

Together, the pair decided to take their studies outside the classroom, to someplace more practical: the edge of poverty itself. Living on $1 a day for two months, they moved to a remote Guatemalan town to study the people's relationship with money and see how access to credit could impact their survival.

They documented their journey in a new film called "Living On One."
