The True Cost of Food is a 15-minute video about the hidden costs of factory farming, industrial agriculture and fast food. It comes with a discussion guide and an excellent Take Action handout. I really like how the Take Action handout is framed — recommending actions based on the issues students care about. The video is presented by the Sierra Club, and it would make a great addition to a unit on food, shopping or label reading.
The movie is produced by Free Range Studios. Their website has a ton of great videos on a wide variety of issues. They’re the folks who did The Story of Stuff and The Meatrix, both of which I’ve used with students in the past. They also have a lot of videos I haven’t seen yet, on issues like the ocean, climate change and fair trade. Many of these include discussion questions and other supplementary materials, which you can find at the websites of the projects themselves. The Free Range Studio website just has the videos.
