I just read a book yesterday called Righteous Porkchop: Finding a life and good food beyond factory farms by Nicolette Hahn Niman. So good, I stayed up to finish it last night and couldn’t sleep, had so much running through my head!!
Nicolette starts out by defining her work for Waterkeepers organization, then she gives some personal information about her life which leads into her knowledge about other animals (such as dairy/beef/egg production), examples of GOOD animal raising, a chapter on how to find good food from good sources, then a great chapter on “Answering obstacles to reform” and tons of references at the end of the book.
Why is this book good? It remains positive and gives great examples and ideas for agriculture that can be safer, healthier, and more cost effective!
I recommend just reading the whole book but in addition here are some online pieces:
