During high school, I took two semesters of writing with a professor who specialized in food writing. Through research papers and such, I collected quite a library of articles and information about different aspects of the food industry such as factory farming, the use of antibiotics in feed, "uneven" agricultural subsidies, high fructose corn syrup, and how all of this relates to our health and the health of the environment.
If anyone wants to delve deeper into the world of the American food industry, I'd really recommend The Omnivore's Dilemma by Michael Pollan and Eating Animals by Jonathan Safran Foer (the same author who wrote Extremely Loud and Incredibly Close, if anyone recognized that). Both are excellent reads, and full of facts. Also, while i'm sure everyone has heard about the documentary "Food Inc." it is an informational source (albeit with a fair dose of pathos) that I would definitely recommend. Along those lines, the documentaries "Frankeinsteer," "King Corn, "Farmageddon," and "Dive!" will give you a good look at different areas of the issue and all are available on netflix!
Additionally, I'll link to some of the articles I've read and incorporated into past papers:
A great article on the emergence of antibiotic resistance in factory farms
A rundown on corn's place in the American diet and as the feed of animals
Agricultural Subsidies and American Health
More on subsidies in this article by Scientific American
Great info on factory farms and their history
I have way more, so if anyone wants a bit more to read feel free to ask. Also, if anyone has any information in this subject that you think would be interesting, let me know!
