Discussions of science and values in risk management have largely focused on how values enter into arguments about risks, that is, issues of acceptable risk. Instead this volume concentrates on how values enter into collecting, interpreting, communicating, and evaluating the evidence of risks, that is, issues of the acceptability of evidence of risk. By focusing on acceptable evidence, this volume avoids two barriers to progress. One barrier assumes that evidence of risk is largely a matter of objective scientific data and therefore uncontroversial. The other assumes that evidence of risk, being "just" a matter of values, is not amenable to reasoned critique. Denying both extremes, this volume argues for a more constructive conclusion: understanding the interrelations of scientific and value issues enables a critical scrutiny of risk assessments and better public deliberation about social choices. The contributors, distinguished philosophers, policy analysts, and natural and social scientists, analyze environmental and medical controversies, and assumptions underlying views about risk assessment and the scientific and statistical models used in risk management.

The American West at Risk summarizes the dominant human-generated environmental challenges in the 11 contiguous arid western United States - America's legendary, even mythical, frontier. When discovered by European explorers and later settlers, the west boasted rich soils, bountiful fisheries, immense, dense forests, sparkling streams, untapped ore deposits, and oil bonanzas. It now faces depletion of many of these resources, and potentially serious threats to its few "renewable" resources. The importance of this story is that preserving lands has a central role for protecting air and water quality, and water supplies--and all support a healthy living environment. The idea that all life on earth is connected in a great chain of being, and that all life is connected to the physical earth in many obvious and subtle ways, is not some new-age fad, it is scientifically demonstrable. An understanding of earth processes, and the significance of their biological connections, is critical in shaping societal values so that national land use policies will conserve the earth and avoid the worst impacts of natural processes. These connections inevitably lead science into the murkier realms of political controversy and bureaucratic stasis. Most of the chapters in The American West at Risk focus on a human land use or activity that depletes resources and degrades environmental integrity of this resource-rich, but tender and slow-to-heal, western U.S. The activities include forest clearing for many purposes; farming and grazing; mining for aggregate, metals, and other materials; energy extraction and use; military training and weapons manufacturing and testing; road and utility transmission corridors; recreation; urbanization; and disposing of the wastes generated by everything that we do. We focus on how our land-degrading activities are connected to natural earth processes, which act to accelerate and spread the damages we inflict on the land.

Carrying only basic camping equipment and a collection of the world's great spiritual writings, Belden C. Lane embarks on solitary spiritual treks through the Ozarks and across the American Southwest. For companions, he has only such teachers as Rumi, John of the Cross, Hildegard of Bingen, Dag Hammarskjöld, and Thomas Merton, and as he walks, he engages their writings with the natural wonders he encounters--Bell Mountain Wilderness with Søren Kierkegaard, Moonshine Hollow with Thich Nhat Hanh--demonstrating how being alone in the wild opens a rare view onto one's interior landscape, and how the saints' writings reveal the divine in nature. The discipline of backpacking, Lane shows, is a metaphor for a spiritual journey. Just as the wilderness offered revelations to the early Desert Christians, backpacking hones crucial spiritual skills: paying attention, traveling light, practicing silence, and exercising wonder. Lane engages the practice not only with a wide range of spiritual writings--Celtic, Catholic, Protestant, Buddhist, Hindu, and Sufi Muslim--but with the fascination of other lovers of the backcountry, from John Muir and Ed Abbey to Bill Plotkin and Cheryl Strayed. In this intimate and down-to-earth narrative, backpacking is shown to be a spiritual practice that allows the discovery of God amidst the beauty and unexpected terrors of nature. Adoration, Lane suggests, is the most appropriate human response to what we cannot explain, but have nonetheless learned to love. An enchanting narrative for Christians of all denominations, Backpacking with the Saints is an inspiring exploration of how solitude, simplicity, and mindfulness are illuminated and encouraged by the discipline of backcountry wandering, and of how the wilderness itself becomes a way of knowing-an ecology of the soul.

We have long recognized technology as a driving force behind much historical and cultural change. The invention of the printing press initiated the Reformation. The development of the compass ushered in the Age of Exploration and the discovery of the New World. The cotton gin created the conditions that led to the Civil War. Now, in Beyond Engineering, science writer Robert Pool turns the question around to examine how society shapes technology. Drawing on such disparate fields as history, economics, risk analysis, management science, sociology, and psychology, Pool illuminates the complex, often fascinating interplay between machines and society, in a book that will revolutionize how we think about technology. We tend to think that reason guides technological development, that engineering expertise alone determines the final form an invention takes. But if you look closely enough at the history of any invention, says Pool, you will find that factors unrelated to engineering seem to have an almost equal impact. In his wide-ranging volume, he traces developments in nuclear energy, automobiles, light bulbs, commercial electricity, and personal computers, to reveal that the ultimate shape of a technology often has as much to do with outside and unforeseen forces. For instance, Pool explores the reasons why steam-powered cars lost out to internal combustion engines. He shows that the Stanley Steamer was in many ways superior to the Model T--it set a land speed record in 1906 of more than 127 miles per hour, it had no transmission (and no transmission headaches), and it was simpler (one Stanley engine had only twenty-two moving parts) and quieter than a gas engine--but the steamers were killed off by factors that had little or nothing to do with their engineering merits, including the Stanley twins' lack of business acumen and an outbreak of hoof-and-mouth disease. Pool illuminates other aspects of technology as well. He traces how seemingly minor decisions made early along the path of development can have profound consequences further down the road, and perhaps most important, he argues that with the increasing complexity of our technological advances--from nuclear reactors to genetic engineering--the number of things that can go wrong multiplies, making it increasingly difficult to engineer risk out of the equation. Citing such catastrophes as Bhopal, Three Mile Island, the Exxon Valdez, the Challenger, and Chernobyl, he argues that is it time to rethink our approach to technology. The days are gone when machines were solely a product of larger-than-life inventors and hard-working engineers. Increasingly, technology will be a joint effort, with its design shaped not only by engineers and executives but also psychologists, political scientists, management theorists, risk specialists, regulators and courts, and the general public. Whether discussing bovine growth hormone, molten-salt reactors, or baboon-to-human transplants, Beyond Engineering is an engaging look at modern technology and an illuminating account of how technology and the modern world shape each other.

Why do we age? Why cooperate? Why do so many species engage in sex? Why do the tropics have so many species? When did humans start to affect world climate? This book provides an introduction to a range of fundamental questions that have taxed evolutionary biologists and ecologists for decades. Some of the phenomena discussed are, on first reflection, simply puzzling to understand from an evolutionary perspective, whilst others have direct implications for the future of the planet. All of the questions posed have at least a partial solution, all have seen exciting breakthroughs in recent years, yet many of the explanations continue to be hotly debated. Big Questions in Ecology and Evolution is a curiosity-driven book, written in an accessible way so as to appeal to a broad audience. It is very deliberately not a formal text book, but something designed to transmit the excitement and breadth of the field by discussing a number of major questions in ecology and evolution and how they have been answered. This is a book aimed at informing and inspiring anybody with an interest in ecology and evolution. It reveals to the reader the immense scope of the field, its fundamental importance, and the exciting breakthroughs that have been made in recent years.

Phoenix, Arizona is one of America's fastest growing metropolitan regions. It is also its least sustainable one, sprawling over a thousand square miles, with a population of four and a half million, minimal rainfall, scorching heat, and an insatiable appetite for unrestrained growth and unrestricted property rights. In Bird on Fire, eminent social and cultural analyst Andrew Ross focuses on the prospects for sustainability in Phoenix--a city in the bull's eye of global warming--and also the obstacles that stand in the way. Most authors writing on sustainable cities look at places like Portland, Seattle, and New York that have excellent public transit systems and relatively high density. But Ross contends that if we can't change the game in fast-growing, low-density cities like Phoenix, the whole movement has a major problem. Drawing on interviews with 200 influential residents--from state legislators, urban planners, developers, and green business advocates to civil rights champions, energy lobbyists, solar entrepreneurs, and community activists--Ross argues that if Phoenix is ever to become sustainable, it will occur more through political and social change than through technological fixes. Ross explains how Arizona's increasingly xenophobic immigration laws, science-denying legislature, and growth-at-all-costs business ethic have perpetuated social injustice and environmental degradation. But he also highlights the positive changes happening in Phoenix, in particular the Gila River Indian Community's successful struggle to win back its water rights, potentially shifting resources away from new housing developments to producing healthy local food for the people of the Phoenix Basin. Ross argues that this victory may serve as a new model for how green democracy can work, redressing the claims of those who have been aggrieved in a way that creates long-term benefits for all. Bird on Fire offers a compelling take on one of the pressing issues of our time--finding pathways to sustainability at a time when governments are dismally failing their responsibility to address climate change.

The energy mix is changing, and renewable energy is growing in importance. If you were born before 1989, you lived in a United States where no electricity was generated from either wind or solar power and very little from geothermal and biomass. By 2018, the combined generation from wind and solar had surpassed hydroelectricity. Fourteen states generated more than 10% of their electricity from wind and three generated more than 30%. And bioethanol, produced from corn grain, made up 10% of the US gasoline market. Changes have also occurred in the nonrenewable energy mix. Coal, which was responsible for 53% of the US electricity generation in 1998 is now only 28%, as natural gas has taken the leadership role, surpassing coal in 2015 as the primary energy for producing electricity. Similarly, the world did not see any electricity generation from wind until 1985 and none from solar until 1989. Now solar plus wind generate 7% of the worldwide electricity. The worldwide demand for all energy types is also increasing rapidly, as energy usage has increased 84% over the last twenty years. This book makes a systematic comparison of twelve different energy types to help understand the driving forces for this changing energy mix. Twelve common criteria are used to provide tools to make these comparisons, such as proven reserves, the levelized cost for each energy type, energy balances, environmental issues, and the energy footprint. Proven reserves are also projected for each renewable energy type.

When we think of "climate change," we think of man-made global warming, caused by greenhouse gas emissions. But natural climate change has occurred throughout human history, and populations have had to adapt to the climate's vicissitudes. Anthony J. McMichael, a renowned epidemiologist and a pioneer in the field of how human health relates to climate change, is the ideal person to tell this story. Climate Change and the Health of Nations shows how the natural environment has vast direct and indirect repercussions for human health and welfare. McMichael takes us on a tour of human history through the lens of major transformations in climate. From the very beginning of our species some five million years ago, human biology has evolved in response to cooling temperatures, new food sources, and changing geography. As societies began to form, they too adapted in relation to their environments, most notably with the development of agriculture eleven thousand years ago. Agricultural civilization was a Faustian bargain, however: the prosperity and comfort that an agrarian society provides relies on the assumption that the environment will largely remain stable. Indeed, for agriculture to succeed, environmental conditions must be just right, which McMichael refers to as the "Goldilocks phenomenon." Global warming is disrupting this balance, just as other climate-related upheavals have tested human societies throughout history. As McMichael shows, the break-up of the Roman Empire, the bubonic Plague of Justinian, and the mysterious collapse of Mayan civilization all have roots in climate change. Why devote so much analysis to the past, when the daunting future of climate change is already here? Because the story of mankindâs previous survival in the face of an unpredictable and unstable climate, and of the terrible toll that climate change can take, could not be more important as we face the realities of a warming planet. This sweeping magnum opus is not only a rigorous, innovative, and fascinating exploration of how the climate affects the human condition, but also an urgent call to recognize our species' utter reliance on the earth as it is.

This collection gathers a set of seminal papers from the emerging area of ethics and climate change. Topics covered include human rights, international justice, intergenerational ethics, individual responsibility, climate economics, and the ethics of geoengineering. Climate Ethics is intended to serve as a source book for general reference, and for university courses that include a focus on the human dimensions of climate change. It should be of broad interest to all those concerned with global justice, environmental science and policy, and the future of humanity.

When it comes to any current scientific debate, there are more than two sides to every story. Controversies in Science and Technology, Volume 4 analyzes controversial topics in science and technology-infrastructure, ecosystem management, food security, and plastics and health-from multiple points of view. The editors have compiled thought-provoking essays from a variety of experts from academia and beyond, creating a volume that addresses many of the issues surrounding these scientific debates. Part I of the volume discusses infrastructure, and the real meaning behind the term in today's society. Essays address the central issues that motivate current discussion about infrastructure, including writing on the vulnerability to disasters. Part II, titled "Food Policy," will focus on the challenges of feeding an ever-growing world and the costs of not doing so. Part III features essays on chemicals and environmental health, and works to define "safety" as it relates to today's scientific community. The book's final section examines ecosystem management. In the end, Kleinman, Cloud-Hansen, and Handelsman provide a multifaceted volume that will be appropriate for anyone hoping to understand arguments surrounding several of today's most important scientific controversies.

DDT Wars is the untold inside story of the decade-long scientific, legal and strategic campaign that culminated in the national ban of the insecticide DDT in 1972. The widespread misinformation, disinformation and mythology of the DDT issue are corrected in this book. DDT contamination had become worldwide, concentrating up food chains and causing birds to lay thin-shelled eggs that broke in the nests. Populations of many species of predatory and fish-eating birds collapsed, including the American Bald Eagle, Osprey, Peregrine Falcon and Brown Pelican. Their numbers recovered spectacularly in the decades following the ban. During the campaign DDT and five other insecticides were found to cause cancer in laboratory tests, which led to bans of these six pesticides by international treaty in 2001. This campaign produced lasting changes in American pesticide policies. The legal precedents broke down the court "standing" barrier, forming the basis for the development of environmental law as we know it today. This case history represents one of the greatest environmental victories of recent decades. DDT is still "controversial" because it has been deceptively interjected into the "climate wars." This campaign was led by the Environmental Defense Fund (EDF), founded in 1967 by ten citizens, most of them scientists, volunteers without special political connections or financial resources. Their strategy was to take environmental problems to court. There were many setbacks along the way in this exciting and entertaining story. The group was often kicked out of court, but a few determined citizens made a large difference for environmental protection and public health. Author Charles Wurster was one of the leaders of the campaign. The first six years of EDF history are described as it struggled to survive. Now EDF is one of the world's great environmental advocacy organizations defending our climate, ecosystems, oceans and public health.

Dirty, Sacred Rivers explores South Asia's increasingly urgent water crisis, taking readers on a journey through North India, Nepal and Bangladesh, from the Himalaya to the Bay of Bengal. The book shows how rivers, traditionally revered by the people of the Indian subcontinent, have in recent decades deteriorated dramatically due to economic progress and gross mismanagement. Dams and ill-advised embankments strangle the Ganges and its sacred tributaries. Rivers have become sewage channels for a burgeoning population. To tell the story of this enormous river basin, environmental journalist Cheryl Colopy treks to high mountain glaciers with hydrologists; bumps around the rough embankments of India's poorest state in a jeep with social workers; and takes a boat excursion through the Sundarbans, the mangrove forests at the end of the Ganges watershed. She lingers in key places and hot spots in the debate over water: the megacity Delhi, a paradigm of water mismanagement; Bihar, India's poorest, most crime-ridden state, thanks largely to the blunders of engineers who tried to tame powerful Himalayan rivers with embankments but instead created annual floods; and Kathmandu, the home of one of the most elegant and ancient traditional water systems on the subcontinent, now the site of a water-development boondoggle. Colopy's vivid first-person narrative brings exotic places and complex issues to life, introducing the reader to a memorable cast of characters, ranging from the most humble members of South Asian society to engineers and former ministers. Here we find real-life heroes, bucking current trends, trying to find rational ways to manage rivers and water. They are reviving ingenious methods of water management that thrived for centuries in South Asia and may point the way to water sustainability and healthy rivers.

Exploring the environmental effects of animal agriculture, fishing, and hunting, Eating Earth exposes critical common ground between earth and animal advocacy. The first chapter (animal agriculture) examines greenhouse gas emissions and climate change, manure and dead zones, freshwater depletion, deforestation, predator control, land and use--including the ranching industries public lands subsidies. Chapter two first examines whether or not the consumption of fish is healthy and outlines morally relevant aspects of fish physiology, then scrutinizes the fishing industry, documenting the "silent collapse" of ocean ecosystems and calling attention to the indiscriminate nature of hooks and nets, including the problem of bycatch and what this means for endangered species and fragile seascapes. Chapter three outlines the historic link between the U. S. Government, wildlife management, and hunters, then systematically unravels common beliefs about sport hunting, such as the belief that hunters are essential to wildlife conservation, that contemporary hunting qualifies as a tradition, and that hunting is merciful, economical, or rooted in "fair chase." At the end of each chapter, Kemmerer examines possible solutions to problems presented, such as sustainable meats, organic and local, grass fed, aquaculture, new fishing technologies, and enhanced regulations. Eating Earth offers a concise examination of the environmental effects of dietary choice, clearly presenting the many reasons why dietary choice ought to be front and center for environmentalists. Kemmerer's writing, supported by nearly 80 graphs and summary slides, is clear, straightforward, and punctuated with wry humor.

There is much we can learn about conservation from native peoples, says Gene Anderson. While the advanced nations of the West have failed to control overfishing, deforestation, soil erosion, pollution, and a host of other environmental problems, many traditional peoples manage their natural resources quite successfully. And if some traditional peoples mismanage the environment—the irrational value some place on rhino horn, for instance, has left this species endangered—the fact remains that most have found ways to introduce sound ecological management into their daily lives. Why have they succeeded while we have failed? In Ecologies of the Heart, Gene Anderson reveals how religion and other folk beliefs help pre-industrial peoples control and protect their resources. Equally important, he offers much insight into why our own environmental policies have failed and what we can do to better manage our resources. A cultural ecologist, Gene Anderson has spent his life exploring the ways in which different groups of people manage the environment, and he has lived for years in fishing communities in Hong Kong, Malaysia, Singapore, Tahiti, and British Columbia—as well as in a Mayan farmtown in south Mexico—where he has studied fisheries, farming, and forest management. He has concluded that all traditional societies that have managed resources well over time have done so in part through religion—by the use of emotionally powerful cultural symbols that reinforce particular resource management strategies. Moreover, he argues that these religious beliefs, while seeming unscientific, if not irrational, at first glance, are actually based on long observation of nature. To illustrate this insight, he includes many fascinating portraits of native life. He offers, for instance, an intriguing discussion of the Chinese belief system known as Feng-Shui (wind and water) and tells of meeting villagers in remote areas of Hong Kong’s New Territories who assert that dragons live in the mountains, and that to disturb them by cutting too sharply into the rock surface would cause floods and landslides (which in fact it does). He describes the Tlingit Indians of the Pacific Northwest, who, before they strip bark from the great cedar trees, make elaborate apologies to spirits they believe live inside the trees, assuring the spirits that they take only what is necessary. And we read of the Maya of southern Mexico, who speak of the lords of the Forest and the Animals, who punish those who take more from the land or the rivers than they need. These beliefs work in part because they are based on long observation of nature, but also, and equally important, because they are incorporated into a larger cosmology, so that people have a strong emotional investment in them. And conversely, Anderson argues that our environmental programs often fail because we have not found a way to engage our emotions in conservation practices. Folk beliefs are often dismissed as irrational superstitions. Yet as Anderson shows, these beliefs do more to protect the environment than modern science does in the West. Full of insights, Ecologies of the Heart mixes anthropology with ecology and psychology, traditional myth and folklore with informed discussions of conservation efforts in industrial society, to reveal a strikingly new approach to our current environmental crises.

The underlying theme of this book is that a widespread, taxonomically diverse group of animals, important both from ecological and human resource perspectives, remains poorly understood and in delcine, while receiving scant attention from the ecological and conservation community. This volume proposes a comprehensive overview of the world's river turtles' ecology, conservation, and management. It begins with a categorization of taxa which inhabit flowing water habitats followed by information on their evolutionary and physical diversity and biogeography. Within the framework of ecology, the authors discuss the composition of river turtle communities in different types of lotic habitats and regions, population dynamics, movements, reproductive characteristics and behavior, predators, and feeding relationships. In a conservation and management section, the authors identify and evaluate the nature and intensity of factors which threaten river turtle survival--almost all of which involve direct human exploitation or indirect effects of human induced habitat alteration and degradation. They then list and evaluate the various schemes which have been proposed or employed to halt declines and restore populations, and make recommendations for future management plans for specific species and regions. In closing, they state their viewpoint concerning future research directions and priorities, and an evaluation of future prospects for survival of the world's river turtle species.

The climate of our planet is changing at a rate unprecedented in recent human history. The energy absorbed from the sun exceeds what is returned to space. The planet as a whole is gaining energy. The heat content of the ocean is increasing; the surface and atmosphere are warming; mid-latitude glaciers are melting; sea level is rising. The Arctic Ocean is losing its ice cover. None of these assertions are based on theory but on hard scientific fact. Given the science-heavy nature of climate change, debates and discussions have not played as big a role in the public sphere as they should, and instead are relegated to often misinformed political discussions and inaccessible scientific conferences. Michael B. McElroy, an eminent Harvard scholar of environmental studies, combines both his research chops and pedagogical expertise to present a book that will appeal to the lay reader but still be grounded in scientific fact. In Energy and Climate: Vision for the Future, McElroy provides a broad and comprehensive introduction to the issue of energy and climate change intended to be accessible for the general reader. The book includes chapters on energy basics, a discussion of the contemporary energy systems of the US and China, and two chapters that engage the debate regarding climate change. The perspective is global but with a specific focus on the US and China recognizing the critical role these countries must play in addressing the challenge of global climate change. The book concludes with a discussion of initiatives now underway to at least reduce the rate of increase of greenhouse gas emissions, together with a vision for a low carbon energy future that could in principle minimize the long-term impact of energy systems on global climate.

As the Earth's oil supply runs out, and the effects of climate change threaten nations and their populations, the search for carbon-neutral sources of energy becomes more important and increasingly urgent. This book focuses on solutions to the energy problem, and not just the problem itself. It describes the major energy-generation technologies currently under development, and provides an authoritative summary of the current status of each one. It stresses the need for a balanced portfolio of alternative energy technologies. Certain solutions will be more appropriate than others in particular locations, due to the differences in availability of natural resources such as solar, wind, wave, tidal and geothermal. In addition, nuclear options (both fission and fusion), as well as technologies such as fuel cells, photovoltaics, artificial photosynthesis and hydrogen (as an energy carrier), all have a potential role to play. A state-of-the-art critique of energy efficiency in building design is also included. Each chapter is written by an acknowledged international expert and provides a non-technical overview of the competing and complementary approaches to energy generation. Broad in scope and comprehensive in treatment, Energy..beyond Oil provides an authoritative synthesis of the scientific and technological issues which are essential to the survival of the human race in the near future. The book will be of interest and use to graduate students and researchers in all areas of energy studies, and will also be highly useful for policy-makers and professionals in the environmental sector as well as a more general readership who wish to learn more about this extremely topical subject.

Millions of people have listened to John H. Lienhard's radio program "The Engines of Our Ingenuity." In this fascinating book, Lienhard gathers his reflections on the nature of technology, culture, and human inventiveness. The book brims with insightful observations. Lienhard writes that the history of technology is a history of us--we are the machines we create. Thus farming dramatically changed the rhythms of human life and redirected history. War seldom fuels invention--radar, jets, and the digital computer all emerged before World War II began. And the medieval Church was a driving force behind the growth of Western technology--Cistercian monasteries were virtual factories, whose water wheels cut wood, forged iron, and crushed olives. Lienhard illustrates his themes through inventors, mathematicians, and engineers--with stories of the canoe, the DC-3, the Hoover Dam, the diode, and the sewing machine. We gain new insight as to who we are, through the familiar machines and technologies that are central to our lives.

Evolutionary Ecology simultaneously unifies conceptual and empirical advances in evolutionary ecology and provides a volume that can be used as either a primary textbook or a supplemental reading in an advanced undergraduate or graduate course. The focus of the book is on current concepts in evolutionary ecology, and the empirical study of these concepts. The editors have assembled a group of prominent biologists who have made significant contributions to this field. They both synthesize the current state of knowledge and identity areas for future investigation. Evolutionary Ecology will be of general interest to researchers and students in both ecology and evolutionary biology. Researchers in evolutionary ecology that want an overview of the current state of the field, and graduate students that want an introduction the field, will find this book very valuable. This volume can also be used as a primary textbook or supplemental reading in both upper division and graduate courses/seminars in Evolutionary Ecology.

For anyone interested in wildlife, birds, wilderness areas, parks, ecology, conservation, environmental literature, and ethics, the name Aldo Leopold is sure to pop up. Since first publication, Aldo Leopold: A Fierce Green Fire has remained the classic short, inspiring biography of Leopold--the perfect companion to reading his ever popular A Sand County Almanac. Winning numerous awards, this comprehensive account of his life story is dynamic and readable, written in the context of the history of American conservation and illustrated with historic photographs. Marybeth Lorbiecki has now enriched A Fierce Green Fire in a way no other biography on Leopold has, adding numerous chapters on the ripple effects of his ideas, books, ecological vision, land ethic, and Shack, as well as of the ecological contributions of his children, graduate students, contemporary scholars, and organizations--and the wilderness lands he helped preserve. Lorbiecki weaves these stories and factual information into the biography in a compelling way that keeps both lay and academic readers engaged. In the introduction to this edition, Lorbiecki makes it clear how much better our lives are because Leopold lived and why today we so radically need what he left us to bring about paradigm shifts in our ethical, economic, and cultural thinking. Instead of losing relevance, Leopold's legacy has gained ever more necessity and traction in the face of contemporary national and world challenges, such as species loss and climate change. Even the phenological studies he started at as a hobby are proving valuable, showing the climatic shifts that have occurred at the Shack lands since the 1930s, recognized by the plants and animals.
