Wendell Berry is not out of line or unrealistic with "The Pleasures of Eating" and his recommendations. I completely agree with his thought process on how society consumes food in today's world and how little thought and practice is given to the art of food.
The suggestions at the end of the chapter are completely doable. Everyone could implement these suggestions it is just dependent on what level they want to implement them.
If there is anything that is more difficult than others it would be #5. I do believe that with the right resources and research you can find out about the details in industrial production. However, that said, I think that industries and mass food productions try to do a very good job at hiding this information so that truths are not known. It is out there though, and as a public we have the right to find out these details.
I really am more enthusiastic about preparing my own food and finding out it origins. I love to cook and I love to make my own creations. The process and exploration of creating new foods is fun to me. Finding out more about local food is intriguing to me, especially in my area (outside the Twin Cities). I think this too could be a fun exploration.
Berry states his reasons and the state of the food economy as "calling it as he sees it". He is not forcing his beliefs on the reader but rather just pointing out what is. Some of this is his opinion but I completely agree with it and was sold by his argument.
