Felipe Luther spends his afternoons studying for a degree from one of Brazil's top universities, tucked in the green hills of Rio de Janeiro above the ritzy beaches of Leblon and Ipanema.
He spends his nights hauling trash in those wealthy communities below.
Once he gets his degree, Luther says one of his goals is to begin teaching college prep courses in low-income communities, opening the door for the next generation of aspiring students.
"I want to give back to other young people by allowing them to hope that this is possible," he said.
