Human Enterprise, Ecosystems, and the Future of Civilization is a book I wrote in 2013 and 2014. It is available as a free pdf here. If you would like to read it on a Kindle, you will have to cough up $0.99 and buy it from Amazon here. Any proceeds will go toward my web hosting costs.
I’ve posted an HTML version here. The content is complete but the formatting is not quite as pretty as the pdf and Kindle versions.
