Land ownership in Guatemala is more unequal than anywhere else in Latin America. Roughly 90 percent of Guatemalan farms are too small to support a family. A tiny group of Guatemalans owns a third of the country's arable land; more than 300,000 landless peasants must scrounge a living as best they can.

When people said Africa would change me, I didn't understand what they meant. To see the poverty in the townships, for instance, is overwhelming. I found it heart-wrenching to see young children walking barefoot and hungry in the dirt. I'm the kind of person who wants to change the world right here and now, so I got frustrated.
