Two really good essays, first from Lee Sandlin is Losing the War, a remarkable essay, perhaps the best available in English, about WWII. I copied the text and made a pdf, and read it off of an e-reader (it’s about 70 pages in MS Word). The second essay is about soil conservation and its role in human civilization (hint: more important than anything else). It was written by former asst. chief of the Soil Conservation Service Dr. WC Lowdermilk, titled “Conquest of the Land through 7000 years” and it chronicles the role soil conservation has played in the history of the rise and fall of empires. It’s eye-opening.
