After a wave of strikes, garbage is all over the streets of Paris.

Massive strikes in Paris against pension reform this week are affecting trash pickup services in the French capital, with piles of waste sitting on many of the city's normally picturesque streets. As of Saturday, 4,400 tonnes of trash were awaiting collection, due to a blockage at trash incinerators caused by the strikes. The municipal government is in charge of garbage collection in half of Paris' 20 arrondissements, while private contractors are responsible for the other 10. The trash buildup has sparked health concerns among Parisians and local politicians, with the mayor of the 17th arrondissement, Geoffroy Boulard, asking Paris Mayor Anne Hidalgo to hire a private service provider to intervene. Boulard said he's also worried about the proliferation of rats and rodents as well as Paris' image.
