Here's the feature on her.
Margaret Peppy (misspelling), 18
Hometown: Chicago
Charity she supports: The Foundation for AIDS Research, amfra.org
Margaret spent last summer living and volunteering in an African orphanage to help with education and day-to-day life. "The children were so independent, because they became orphans at such an early age," she says. "We were basically filling in for their parents, many of whom died from AIDS. It's a catastrophe. There is a lack of education there, and people are afraid to talk about it. We need to stop the spread (of AIDS) any way we can."
