There is not one action that needs to be taken to fix our broken food system. Rather, there are hundreds, if not thousands, because the system is broken in so many places.

This Saturday, Oct. 24 on Food Day, a short but powerful documentary will be officially released in conjunction with the thousands of Food Day events that are happening nationwide. "Food for Thought, Food for Life" by filmmaker, designer and philanthropist Susan Rockefeller was a selection at the Short Film Corner at Cannes 2015 and at the 2015 Sarasota Film. The film highlights several of the broken areas in our food system and introduces viewers to passionate people who are taking some of the actions necessary to mend the brokenness.

A peek at the trailer gives a good overview of what the film addresses.

At the end, Fred Kirschenmann from the Stone Barns Center comments that there is a sense that we are at the beginning of a revolution within our food system. I've seen the film in its entirety, and in its 22 minutes it presents many fronts of that revolution with an honest sense of urgency. Soil health, biodiversity, the problems with monocultures, seed saving, agriculture subsidies, food desserts, urban gardening, food-related health issues, climate change and other areas the revolution must touch are presented quickly, but informatively.

It would be possible for a film that touches upon so many problem areas so quickly and with such urgency to leave a viewer feeling overwhelmed by the enormity of the broken food system, but "Food for Thought, Food for Life" did the opposite for me. It left me feeling energized and full of hope because of the passionate warriors on the front lines of the revolution.

Even if participating in Food Day isn't part of your plans on Saturday, you can still watch the entire film. Head over to the "Food for Thought, Food for Life" official website and submit your email. When you do, you'll get access to the film. If the film leaves you feeling energized, hopeful and ready to join the revolution, the website also points you to resources that will help you get involved practically and politically with specific actions that you can take.
