POCATELLO — This Sunday is a free film day at the Bengal Theater in the Pond Student Union with acclaimed environmental documentary “Common Ground” showing at 4 and 7 p.m. This Palm Springs and Tribeca Film Festival-winning story about sustainable farming explores how many of the problems in the world connect to the state of the world’s soil. Independent farmers, implementing historic Indigenous techniques, demonstrate how changing agricultural practices could potentially help address climate change and save the world.

“One of the most powerful, illuminating and vital wake-up calls since Food, Inc.,” writes NYC Movie Guru while Film Threat calls it, “That rare documentary that actually proposes solutions … practical solutions.”

All are welcome to attend. The film is sponsored by the Pocatello Film Society, along with the Idaho State University Political Science Department, the Portneuf Resource Council and the Pocatello League of Women Voters. Before and after the film, several organizations will have tables set up in the theater lobby with information on sustainable agriculture and other environmental causes.
