Greenpeace has produced a series of graffiti actions in Lyon to urge the authorities to react to air pollution. In recent days, while Lyon suffocated under fine particles, dozens of "clean" graffiti have blossomed on the walls and sidewalks to denounce air pollution. "We want to breathe", "Lyon, suffocate, air!" This operation, led by Greenpeace with Alternatiba / ANV Rhône, aims to encourage local authorities to implement a proactive policy to improve air quality.
