You can download the free ebook From This Green Earth: Essays on Looking Outward at Amazon, Amazon UK, Barnes & Noble, Apple Books, Kobo, Google Play (PDF format), and Smashwords, (Amazon sometimres prices it at 99 cents without informing me; if this happens get the mobi format at Smashwords.)

There is no print edition, but if you prefer to see pages rather than flowing text you can get a pdf edition at Google Play that's formatted just like a book (rather than like a manuscript) and you can print it if you want to. (It's called "original pages" rather than "pdf" on the order page.) Also, there is a short sampler paperback containing 12 essays from my essay collections, since the ebooks are too long to be issued in paperback at reasonable prices.
