Although Monsanto (nowadays a part of the Bayer imperium ) is just one of the many chemical companies that make up the food industry, it acts as the role model for companies that are purely profit – and greed driven and have no remorse at all for the damage to the food supply they cause.   

This documentary from HustleBlast zooms in to the history of Monsanto, but you could make a similar documentary on any other chemical company that is operating in the food industry.
