Maine Sierra Club continues its Penobscot Bay Film Series with a screening of “A Fierce Green Fire,” Part 1, Wednesday, Oct. 29, at 6 p.m. in the Abbott Room of Belfast Free Library, 106 High St.

The documentary “A Fierce Green Fire: The Battle for a Living Planet” is the first big- picture exploration of the environmental movement — grassroots and global activism spanning 50 years from conservation to climate change. It focuses on activism, people fighting to save their homes, their lives, the future and succeeding against all odds. Narrated by Robert Redford, Ashley Judd, Van Jones, Isabel Allende and Meryl Streep, the film premiered at the 2012 Sundance Film Festival and won acclaim at festivals around the world.

The first half of “A Fierce Green Fire: The Battle for a Living Planet” will be shown to give sufficient time for post-film discussion, which will be led by Becky Bartovics. The longtime local activist in the Penobscot Bay area lives on North Haven and co-chairs the executive committee of Sierra Club Maine.

Admission is free. The second half of the film will be screened and discussed Wednesday, Dec. 10. For more information, call 761-5616, email maine.chapter@sierraclub.org or visit maine.sierraclub.org.
