“Thinking like a mountain is a term coined by Aldo Leopold in his book A Sand County Almanac. In the section entitled “Sketches Here and There” Leopold discusses the thought process as a holistic view on where one stands in the entire ecosystem. To think like a mountain means to have a complete appreciation for the profound interconnectedness of the elements in the ecosystems. It is an ecological exercise using the intricate web of the natural environment rather than thinking as an isolated individual.” From the Wikipedia article about Aldo Leopold
A Sand County Almanac, was published shortly after Leopold’s death in 1949. It came to prominence at the first Earth Day in 1970. It includes another influential essay, The Land Ethic, which discusses our moral responsibility to the natural world.
