I find it interesting that a small town in Italy is looking to cut greenhouse gases by creating foot buses, groups of kids walking to school together. Seems like a great idea to me. From the New York Times:
They set up a piedibus (literally foot-bus in Italian) — a bus route with a driver but no vehicle. Each morning a mix of paid staff members and parental volunteers in fluorescent yellow vests lead lines of walking students along Lecco’s twisting streets to the schools’ gates, Pied Piper-style, stopping here and there as their flock expands.
