NAU’s Environmental Caucus and the Office of Sustainability will host a “Better World” film series this October.

The series will feature documentaries that “show society’s greatest challenges and celebrate the human spirit,” said Ellen Vaughan, manager of the Office of Sustainability.

Films will be screened most Thursday nights at 5 p.m. in The Green Room, 15 N. Agassiz St. The films are free and open to the public.

A complete listing of films is online.
