The Environmental Endgame: Mainstream Economics, Ecological Disaster, and Human Survival ReviewThis slim book is a popularization of Nadeau's earlier, more scholarly work "The Wealth of Nature: How Mainstream Economics Failed the Environment". It's a solid and sorely needed critique of mainstream economics, based on up-to-date developments in physics and mathematics as well as environmental science.
For example, real-world economics is described as an `open system' with energy, resource, and regulatory inputs, operating under a regime that is frequently chaotic due to `feedback loops'. This is in sharp contrast to the `closed-system' axioms of neo-classical economics, focused on the mathematics of `equilibrium', with environmental issues relegated to `externalities'. And when Nadeau started listing the many false assumptions of neo-classical economics, such as limitless growth and perfectly rational economic actors, then I became eager to see this breath of fresh air blow away the `dismal science' of yore.
Nadeau characterizes the fundamental failure of neo-classical economics as an understanding of part-whole relationships based on out-of-date Newtonian thinking. Several illuminating chapters are devoted to analyzing the historical development of neo-classical economics. Yet I found the `part-whole' discussion rather opaque. It seems to be an unsuccessful attempt to popularize the difference between a modern open-system understanding informed by the mathematics of nonlinear dynamical systems and chaos theory, versus the classical closed-system understanding associated with the law of the conservation of energy and the linear differential equations of Newtonian physics.
In fact the part-whole critique comes off as somewhat ideological. It has the virtue of denouncing the false assumption that there is an `invisible hand', or `natural law' of economics, guiding economies toward perfect equilibrium if government, assumed to be external to the closed-system, would only keep its hands off. Yet I think that a more successful critique would be to just demonstrate that the neo-classical model is a very bad model for the real world, except in very specialized circumstances. I also found the opening gambit of the `Godgame', though well intentioned, to be somewhat offputting.
The larger task is to actually construct a new `ecological economics' based on the new mathematics and physics. Nadeau says that mainstream economists haven't been listening to the ecological economists, however correct they may be. Therefore he has launched a more direct attack on the foundations of neo-classical economics. But I think what is missing is the mathematical development of ecological economics, to the point where this new economics supplies much better quantitative tools, not just qualitative analysis, for economists to do there jobs.
A big obstacle here is the need to change the mindset of economists for prediction to scenarios. The neo-classical economics of equilibrium is ideally suited to prediction. And in very specialized or short term circumstances these predictions can be accurate, with customary statistical confidence intervals. But the real world of economics is more like the weather, a chaotic system.
So how are climate scientists now predicting climate change over the coming centuries? They use scenarios, to give people a sense of the range of possibilities, so that we may be prepared. Moreover, these scenarios put the focus squarely where it needs to be: On the validity of the assumptions that go into the scenarios. A global economy based on a wide range of scenarios will become adaptable and resilient, instead of highly optimized for one particular scenario, e.g., 'just-in-time' supply lines.
In economics this quantitative approach was actually pioneered decades ago by the "Limits to Growth" project, though it was neglected by mainstream economists. This celebrated and still worthy project was fully grounded in the nonlinear dynamics of feedback loops and scenarios based on just a few global variables, such as population, food, industry, and resources. This work needs not only its own axiomatic development, but a vast extension to deal with the ecological, political, and economic world at all levels, in both theory and practice.
An example is that control theory for chaotic systems teaches that very little energy, if properly applied over time, is needed to guide a system that is on the `edge of chaos'. Thus a democratically constituted economic authority could successfully guide the global economy with a gentle, not heavy, hand, if it has patience and the proper levers. Nadeau, to his credit, recognizes the need for democratic global governance to tackle the many global crises that are already becoming manifest.
Unfortunately Nadeau does not point us to who is actually doing this exciting development of post-Newtonian economics. I suspect the reason is that the real science of economics is still in its infancy and it is up to us to develop it. Thanks to Robert Nadeau for throwing down the gauntlet.
The Environmental Endgame: Mainstream Economics, Ecological Disaster, and Human Survival OverviewFor decades, scholars have warned of an impending global environmental crisis. Yet politicians, particularly in the United States, have consistently shown that they are not taking the threat seriously. Initiatives aimed at protecting the planet are commonly seen as belonging to a category unto themselves-the preserve of scientists and environmental enthusiasts.In this groundbreaking book, Robert L. Nadeau warns that we have moved menacingly close to a global environmental catastrophe and that to evade this fate we must stop drawing a distinction between issues that are "environmental" or "scientific" and those that reside in the sphere of "real life." Although scientists have attempted to bring ecological concerns to the forefront of global issues, problems are rarely communicated in ways that can be readily understood by those outside the scientific community.Bringing together perspectives from a variety of disciplines, including economics, politics, biology, and the history of science, The Environmental Endgame articulates the concerns of scientists in a way that they become the real-life, tangible concerns of people around the world. Nadeau asserts that we have entered a new phase of human history that cannot be one of separation and division but must be one of cooperation and mutual goals.Nadeau demonstrates that our current governmental and financial institutions, based on neoclassical economics, lack the mechanisms for implementing viable solutions to large-scale crises. Such steps cannot be taken without moving beyond the power politics of the nation-state system. The book concludes with a call to view the natural world as part of humanity, not separate from it. This unifying worldview would be a catalyst for implementing the international government organizations necessary to resolving the crisis.The Environmental Endgame is an ambitious and timely book that will change the way we think about our economy, our government, and the environment. It should be read by everyone who cares about the pervasive neglect and abuse of planet Earth and wants to know what can be done about it.

Perfection: Coming to Terms with Being Human ReviewI think Michael Hyde is one of the most brilliant minds in his subject area. When I attended Wake Forest some 12-14 years ago I had the honor of taking a linguistics class which he taught. To this day, he is one of the only professors I can remember by name. The other reviewer should have read the product description before purchasing, as it clearly states, "he ponders the consequences of the perfection-driven impulse of medical science." You can not get a clearer explanation of what to expect in terms of subject matter.Perfection: Coming to Terms with Being Human OverviewIn a masterful survey of the history of the idea of human perfection, prize-winning author and noted rhetorician Michael J. Hyde leads a fascinating excursion through Western philosophy, religion, science, and art. Eloquently and engagingly he delves the canon of Western thought, drawing on figures from St. Augustine and John Rawls to Leonardo da Vinci and David Hume to Kenneth Burke and Mary Shelley. On the journey, Hyde expounds on the very notion and Otherness of God, the empirical and ontological workings of daily existence, the development of reason, and the bounds of beauty. In the end, he ponders the consequences of the perfection-driven impulse of medical science and considers the implications of the bourgeoning rhetoric of our posthuman future. It is nothing short of a triumphant examination of why we humans are challenged to live a life of significant insignificance.

Ecological Models and Data in R ReviewThis book, in part, was developed from Dr. Bolker's graduate course in Ecological Models and Data at the University of Florida. This was the best course I took as a graduate student, it transformed the set of quantitative tools I was able to bring to bear on ecological questions. There was so much worthwhile material covered in this class that I took it twice (UF only counted the first time:). Since graduate school I still frequently refer to my notes from the class. With the publication of "Ecological Models and Data in R" even those who didn't have the good fortune of being in Bolker's class can learn approaches for integrating ecological theory and data. Bolker's book covers much of the material from his course and thus is an excellent resource for graduate students and faculty alike.Ecological Models and Data in R Overview
Ecological Models and Data in R is the first truly practical introduction to modern statistical methods for ecology. In step-by-step detail, the book teaches ecology graduate students and researchers everything they need to know in order to use maximum likelihood, information-theoretic, and Bayesian techniques to analyze their own data using the programming language R. Drawing on extensive experience teaching these techniques to graduate students in ecology, Benjamin Bolker shows how to choose among and construct statistical models for data, estimate their parameters and confidence limits, and interpret the results. The book also covers statistical frameworks, the philosophy of statistical modeling, and critical mathematical functions and probability distributions. It requires no programming background--only basic calculus and statistics.

Practical, beginner-friendly introduction to modern statistical techniques for ecology using the programming language R
Step-by-step instructions for fitting models to messy, real-world data
Balanced view of different statistical approaches
Wide coverage of techniques--from simple (distribution fitting) to complex (state-space modeling)
Techniques for data manipulation and graphical display
Companion Web site with data and R code for all examples

Spatial Conservation Prioritization: Quantitative Methods and Computational Tools ReviewThis book provides a well-written and accessible introduction to new methods for quantitative conservation planning that have been developed over the past decade. Beyond an audience of planners who actually apply these methods, it is also suitable for conservation biologists who are looking for a general introduction to the concepts underlying this field. It would serve as a good textbook for a seminar in quantitative conservation planning, as the chapters generally combines a high level of detail with a style accessible to graduate and advanced undergraduate students.Spatial Conservation Prioritization: Quantitative Methods and Computational Tools OverviewHabitat loss and deterioration, climate change, and economic pressures for resource extraction have all led to a global loss of biodiversity. The limited resources available for conservation need to be used both effectively and efficiently in order to minimise further losses. Spatial conservation prioritization addresses the question of how we should allocate conservation effort and funds in space and time. While the benefits of quantitative conservation prioritization methods have been widely promoted, adoption of these methods in "real-world" planning and implementation is still in its infancy, partly due to the difficulty of identifying which methods and tools (if any) are suited to specific planning problems. Spatial Conservation Prioritization brings together a team of leading scientists to introduce the conceptual and methodological aspects of how to undertake spatial conservation planning in a quantitative manner. It provides the reader with information on when, why, and how to use which statistical and computational methods for conservation prioritization. Important topics underlying spatial prioritization including metapopulation modelling, population viability analysis modelling, species distribution modelling, and uncertainty analysis are discussed, as well as operational definitions and methods. The book includes chapters on the most widely used and latest software, and concludes with an insight into the future of the field.
