I could not find the selection that is missing in your question but I assume that you are talking about Eric Schlosser. He is most famous for his investigative journalism. He wrote ''Fast Food Nation'' and I think that you are talking about it because it is his most famous work.
In ''Fast Food Nation'' he is trying to inform people about the food they are eating at the fast-food restaurants and about what is prepared for them. The main idea of his work was to show everyone what the food production and preparation in America actually is and how commercialism and consumerism are having an effect on us and our children.
He surely wanted people to eat healthier and to be aware of the fast-food restaurant and how bad that kind of food can be for us.
But since the question is what he 'might' wanted I think that it is considering our\my own opinion and I think that he also might want people to begin avoiding meat. I think that because he was talking a lot about meat preparation and also later in the movie ''Chew on this'', an adaptation of ''Fast Food Nation'', he is talking about the ways chickens die and how the meat is packed and more.
However, I think that, they do this so that you know the original way of printing newspapers and see how the history of printing press has grown over time especially after the industrial revolution
