ROME (AP) — Pope Francis says small gestures can improve a city's life, as he spoke at a religious ceremony to mark the official start of Rome's Christmas season.

Francis prayed Sunday at the foot of a towering column topped by a statue of the Virgin Mary.

Italians consider Dec. 8 — a national holiday and a religious feast day honoring Mary for the Catholic church — the start of the holiday season.

Francis says it's in the ‘’little gestures and the big choices" that the quality of life can improve and the social climate can become ‘’more breathable."

The annual ceremony takes place near Rome's Spanish Steps and near its upscale shopping district and tourists and Romans flocked to see the pontiff, including the city's mayor.

Rome's frequent garbage pileups on the streets and its polluted air have plagued city residents, making quality-of-life discussions a key topic.
