Aldo Leopold and the Ecological Conscience [PDF ebook] 

In Aldo Leopold and an Ecological Conscience ecologists, wildlife biologists, and other professional conservationists explore the ecological legacy of Aldo Leopold and his A Sand County Almanac and his contributions to the environmental movement, the philosophy of science, and natural resource management. Twelve personal essays describe the enormous impact he has had on each author, from influencing the daily operations of the U.S. Fish and Wildlife Service and the creation of a land-use ethics guide for Forest Service personnel, to much needed inspiration for continuing on in today’s large, complex and often problematic world of science. Here is Aldo Leopold as a mentor, friend, and companion and an affirmation of his hope that science will continue to be practiced in the cause of conservation.
