In Thinking Green: Ethics for a Small Planet, author-activist Karel Rogers, PhD, insists that mankind reconsider how they feel about their place on earth. As a call to arms, she illustrates how humans are a part of nature, subject to the natural order that continues to evolve. In four sections including "Rethinking Core Issues" and "The Challenges We Face" and twelve chapters such as "Time, Species, Global Perspective," "People Are a Part of Nature," and "The Great Unfolding Story," she provides evidence, hope, and a broadened definition of evolution that includes any system that changes through time as a result of selective pressures. Perfect for students of environmental studies, Rogers deftly guides readers to put critical issues in perspective by looking first at the individual and then the species. From there, she challenges readers to face serious issues and ultimately accept a different world in which making ethical and sustainable choices is inherent to freedom and prosperity.
