With 3.6 billion pounds of Roundup sprayed annually on crops grown in the United States the investigative documentary Children of the Vine couldn’t be more timely. The unsettling investigation into the controversial herbicide Roundup and its impact on public health was directed by award-winning filmmaker Brian Lilla who after moving to Napa Valley witnessed a nightmare unfolding around him as farm workers sprayed vineyards with thousands of gallons of Roundup each winter.

At the center of this controversy is glyphosate the primary active ingredient in Monsanto’s Roundup. Glyphosate is now found in breast milk baby food wine and 80% of food grown in the United States. Why are countries banning Roundup while U.S. farmers use more of it than any other country in the world?
