I'm currently reading "Leopold". "Leopold" is an expanded version of his writings and contains all the essays from "A Sand County Almanac" and "Round River" which I had read previously. Aldo Leopold is considered one of the early fathers of modern day conservation. Although well traveled as a naturalist he ended up in Madison as a professor and bought a distressed farm along the Wisconsin River south of Madison. The essays take a look at our "relationship" to the "land" which includes all the flora, fauna and water. His writings have a profound influence on how I relate our natural world.
