BOZEMAN – Filmmakers Kip Andersen and Keegan Kuhn have announced the Bozeman premiere of their new film “Cowspiracy: The Sustainability Secret,” with a free screening on Saturday, April 18 at 7 p.m. at The Ellen Theatre.

The documentary is 90 minutes long and will be followed with a Q-and-A session led by Dr. Lisa Kemmerer, author of “Eating Earth: Environmental Ethics and Dietary Choice.” Tickets are not required; seating will be available on a first come, first served basis.

“Cowspiracy” is a groundbreaking, feature-length, environmental documentary following an intrepid filmmaker as he uncovers the most destructive industry facing the planet today – and investigates why the world’s leading environmental organizations are too afraid to talk about it.

At a time when whole regions are in drought, oceans are dying, and severe weather is becoming the norm, “Cowspiracy” seeks to find the real reasons why this is happening and what we can do about it.

As eye opening as “Blackfish” and as inspiring as “An Inconvenient Truth,” this shocking yet humorous documentary reveals the devastating environmental impact large-scale factory farming has on our planet.

Kemmerer’s new book helps readers understand what they can do to offset the negative impacts of animal agriculture on the environment. She said she hopes it will help develop awareness that individuals’ personal choices make a difference to our environmental health.

“What [we] choose to eat for lunch matters to the planet,” said Kemmerer, who also teaches ethics and religion at Montana State University–Billings. “Rather than looking to what corporations are doing, we can [ask] ‘What can I do to make the earth more sustainable?’ Diet is key as it turns out.”

Complimentary film DVDs and refreshments will be available during the fifth annual Worldwide Vegan Bake Sale, taking place in The Ellen’s lobby from 3–7 p.m.

Everything sold at the bake sale will be 100 percent plant-based. There will also be many gluten-free, organic, and raw items. All proceeds will go to the nonprofit “Live and Let Livingston,” to maintain their ever-growing lending library of cookbooks and documentaries, educational resources and monthly potlucks/cooking demos.Free screening of “Cowspiracy” at The Ellen April 18.
