1) Ishmael by Daniel Quinn, which offers the most convincing explanation I’ve ever seen as to why our global civilization is wrecking the world. It’s written as a novel but most certainly addresses our culture.
2) This Changes Everything: Capitalism vs. the Climate by Naomi Klein
3) Desert Solitaire by Edward Abbey
4) Bringing Nature Home by Doug Tallamy
5) Planting in a Post-Wild World by Claudia West and Thomas Rainer
6) The Unsettling of America by Wendell Berry
7) A Sand County Almanac by Aldo Leopold. Beautiful vignettes from his farm up in Wisconsin where he applies (at the time new) concepts of ecology and land ethic. A true pioneer in the fields of land management and conservation.
8) Drawdown by Paul Hawken because it supplies the solutions to climate change, many of which will help solve other environmental issues.
9) Cultivating an Ecological Conscience by Fred Kirschenmann
10) One Straw Revolution by Masanobu Fukuoka. Oldie but goodie. Introduces organic farming permaculture in an accessible, straightforward writing style.
