Caleb Kenna for The Chronicle Review A friend of mine who works at Saint John's University and the College of Saint Benedict, in Minnesota, recently told me a story: Her book group read Anna Lappé's Diet for a Hot Planet, one of many recent books to focus on the vulnerabilities of the industrial food system and the threats posed by climate change.

Yeah, I wasn't sure if I did it right. How do you share it? haha. Sorry, I'm technologically challenged.
