CAMBRIDGE, Mass. (AP) -- Sean Penn remembers smelling dead bodies when he arrived in Haiti after the earthquake.
But now there's music in those same streets even as the country faces many years of rebuilding, the Academy Award-winning actor said Tuesday.
Penn said "extraordinary" changes have happened since the Jan. 12, 2010, natural disaster killed more than 300,000 people and left about 1.5 million homeless.
He also called the Haitian people resilient in his remarks in a forum at Harvard's Kennedy School of Government.
The actor is an ambassador-at-large for Haiti's president and CEO of aid group J/P Haitian Relief Organization, which started with a goal of bringing painkillers to earthquake victims. It became an agency that manages a camp for displaced people and works to resettle them. It also does other aid work such as clearing rubble, repairing damaged homes and running a community center and clinics.
Penn said investment in manufacturing and jobs in Haiti would help solve the challenges because displaced people need work. He also said relief organizations can make a difference by helping with education initiatives because the first thing parents ask before resettlement is where their children will be going to school.
