detropia
“Detropia” is one of several films being screened this weekend as part of the Princeton Environmental Film Festival at the Princeton Public Library.

Friday, January 25

The seventh annual Princeton Environmental Film Festival kicked off Thursday night at the Princeton Public Library. The free festival runs for three consecutive four-day weekends through Feb. 10. The festival features documentary films, presentations and speakers that explore environmental sustainability from a wide range of perspectives. A complete schedule can be found on the library’s website. Tonight, festival goers will watch “Detropia”. Told through the eyes of people struggling to stay in the city of Detroit despite its decline, this documentary features artistic and haunting images of a once grand city on the brink of dissolution. Refusing to abandon hope or resistance, the residents reflect the spirit of the Motor City, its battle to survive in postindustrial America and its trudge toward a radically different future. Along the way, the film reveals a correlation with the rest of middle-class America and the widening chasm of income inequality. The screening starts at 7 p.m. in the library’s community room.
