We talked a bit about food systems, but to wrap it all up, watch this 15 minute video put out by the Sierra Club called the true cost of food. If the link doesn't work just google 'true cost of food'. Comment on the video and at least one other person's comment.
What was your impression? Did anything in particular stand out? Have you considered these other implications when buying or eating? How does food affect the environment, economies, communities, your health? How does this relate to learning to grow some of your own food?
