This is a clip from the French documentary "The World According to Monsanto." It summarizes the history of Agent Orange, a toxic herbicide produced by Monsanto, Dow Chemical, and other companies. It was sprayed extensively during the Vietnam War, leading to a horrific variety of adverse health effects. Monsanto conducted deliberately flawed and coercive studies to "prove" that Agent Orange was safe, causing many Vietnam veterans to be denied sufficient health benefits.
In the late 1990's, Monsanto changed its focus from chemicals like Agent Orange to biotechnology. It now indirectly controls approximately 60% of the world food supply. Monsanto insists that its genetically modified crops are safe.
