It’s been 50 years since the United States attempted a conservation revolution with the passing of the Endangered Species Act in 1973. Now, fifty years later, the Fish and Wildlife Service finds itself at a crossroads: some recovery efforts are succeeding, but too many are either failing or stuck in neutral, even after decades of work. Take, for example, the story of two cranes, the whoopingcrane of southeastern Texas and the red-crowned crane of northern Japan. Both were pushed to the brink of extinction by the early 1900s, with surviving populations numbering as few as 20 to 40 individuals, and are now the subjects of concerted recovery efforts led by advanced national governments. The U.S. Fish and Wildlife Service has focused mainly on habitat protection, while at Japan’s Ministry of the Environment, conservation authorities have leaned most heavily on direct population survival via a long-standing winter feeding program. These two case studies provide a template for comparing different approaches towards endangered species: habitat management vs. population management. Thus far the Japanese approach has proved more successful, but the story isn’t over yet. What can these lessons teach us about managing other endangered species? Can species rehabilitation be standardized, or must each effort be designed and implemented on a case-by-case basis? A Tale of Two Cranes will serve as a launching pad for better understanding the progress and pitfalls inherent in endangered species management, through 50 years of lessons learned since the landmark Endangered Species Act was enacted by the United States Congress in December 1973. Also considering its success stories like the Attwater’s prairie chicken, the ESA has had an enormous impact on conservation theory and practice throughout the world, from Tasmanian devils in Australia to the vaquita porpoises of Mexico. But, worsening government budget constraints, public inattention, and a continuous string of setbacks experienced within numerous rehabilitation initiatives will all eventually conspire to challenge the conventional thinking on endangered species management like never before. Author Nathanial Gronewold explains how we got here, where things stand today, and what lessons conservationists must take to heart as the world continues to struggle to put a halt to an ongoing global extinction crisis.

Does modern economic theory violate some basic, fundamental laws of physics? That is the question that award-winning environmental and energy writer Nathanial Gronewold sets out to answer in Anthill Economics. Gronewold points out that the modern school of economics is missing a significant piece of the puzzle: energy. And not just oil, or natural gas or wind power, but rather the fundamental importance of energy in transforming matter into food, shelter, and material possessions. Ecologists have been using the principles of biophysics –population density, energy return on investment, and habitation patterns –to study ecosystems for centuries. But what if those same principles hold the key to the global human economy? After all, at its core, the global economy is simply humanity’s ecosystem.Anthill Economics puts forth an innovative and cross-disciplinary approach, asserting that biophysical laws are just as fundamental to the global economy as they are to zoology and entomology. The rollercoaster-like rise and fall of caribou population on a remote island can teach us about resource allocation and global inequality. The behavior of squirrels gathering nuts is a lesson in economic energy return on investment and wage stagnation. Could human traffic patterns mimic the daily pulse of ants in the forests marching in and out of their own central business districts? And, will global warming change these patterns for humans and insects alike? This clearly written book full of illuminating ecological analogies gives readers an informed and entertaining introduction to the cutting-edge field of biophysical economics –also known as thermoeconomics –that seeks to provide a more complete understanding of the global economy. The result is a radical new way of looking at the world and how the laws of physics and nature can be used to more precisely understand human demographics, population patterns, and economics.
