People need to listen more if they want there to be peace in the world, Pope Francis said.

Open "ears are missing, there's a lack of people who know how to listen," which is essential before there can be dialogue, he said during an audience on March 11 with volunteers for a national help hotline, Telefono Amico Italia.

"If only there were more dialogue -- true dialogue, that is -- in families, in the workplace, in politics, so many issues would be more easily resolved," he told members of the association, which was celebrating its 50th anniversary.
