"The World According to Monsanto," a documentary film about the global agricultural seed and chemical producer Monsanto Co., will be screened Thursday, June 7, at the Fairfield Public Library.

The screening is planned at 6:30 p.m. in the Rotary Room of the main library, 1080 Old Post Road. The program is free, but registration is required.

The film is the result of a three-year investigation by journalist and documentary filmmaker Marie-Monique Robin that covered four continents, the library said in a news release. Monsanto, which once produced the defoliant Agent Orange and other toxic chemicals, now is the leading producer of genetically modified corn and soy seeds.

The film concludes that the new "green" face of the company and its production of genetically modified organisms is "no less maligning" than its caustic-chemicals past, the release said.

After the film, a discussion will be led by Tara Cook-Littman, a certified holistic-health counselor and co-founder of RightToKnowCT.org, and Glen Colello, co-owner of Catch a Healthy Habit Cafe.
