This is an article I wrote to make the case that agriculture, and therefore civilization, is unsustainable. I think it should be of interest to many here. The original title was “Agriculture: the beginning and end of civilization.” But I figured the new one might be more attention-getting. :o

P.S. The Canyon Country Zephyr is a smallish, now online, paper out of southern Utah. It’s publisher, Jim Stiles, has been putting it out for over twenty years. Google “brave new west” for the trailer for a documentary about his paper and his efforts to save the land in that part of the country.
