Neil Young and Monsanto are once again trading barbs over genetically modified organisms (GMOs). This time, it’s over Young’s new documentary, “Seeding Fear,” the story of Alabama farmers Michael White and his father who were sued by the agrochemical giant in 2003 for patent infringement of its GM soybeans.

The lawsuit between the Whites and Monsanto was settled in 2006 out of court.

“Even after the lawsuit was over, I couldn’t make him believe it was over. He would cry and keep saying, ‘Oh, they’re going to come back and sue me again,’” Michael says in the documentary. “It destroyed him. It destroyed his life. He went to his grave—this grave—still afraid of [Monsanto].”

Young, a co-executive producer of the film, wrote on Facebook, which has more than 3 million likes, “Monsanto is a corporation with great wealth, now controlling over 90 percent of soybean and corn growth in America. Family farms have been replaced by giant agri corp farms across this great vast country we call home. Farm aid and other organizations have been fighting the losing battle against this for 30 years now.”

“The film I would like you to see tells the story of a farming family in America, but the same thing is happening around the world,” Young added. “It is a story that takes 10 minutes of your time to see. It is a simple human one, telling the heartbreaking story of one man who fought the corporate behemoth Monsanto, and it illustrates why I was moved to write ‘The Monsanto Years,’” referring to the “Rockin’ in the Free World” singer’s latest album that attacks the corporation.
