Legendary conservationists show us that we still have the power to prevent critical consequences of the sixth extinction in this game-changing book.

Can we save threatened animals and ecosystems in the midst of a mass extinction? The answer is a resounding yes! Before They Vanish shows us how. In this wise and impassioned book, renowned conservation scientists Paul R. Ehrlich, Gerardo Ceballos, and Rodolfo Dirzo urge us to shift our thinking rather than succumb to grief over the losses that humanity faces. This comprehensive look at a crucial but often overlooked aspect of conservation--population extinction, or the loss of a species within a specific geographic location--guides us onto a new, hopeful path.

The authors argue that conservationists have placed too much emphasis on the extinction of entire species, which occurs gradually enough that we only detect it in the direst of cases. By that time, meaningful action may be impossible. By shifting our focus to identifying extinction threats at the more localized population level, we can intervene more rapidly and effectively to prevent broader declines before it's too late. This change in perspective represents a critical step in saving these vanishing species; early detection and intervention may be our last, best hope for stemming the tide of this global crisis.

Using examples from the worlds of vertebrates, invertebrates, plants, fungi, and microorganisms, the authors explain the concept of population extinction, its causes and consequences, and how to prevent the mass destruction of the amazing and unique creatures with whom we share our planet. This call to action is a must-read for anyone concerned with saving endangered and threatened species, our natural world--and ourselves.

A renowned scientist and environmental advocate looks back on a life that has straddled the worlds of science and politics

Compelling. . . . [Ehrlich's] memoir includes remarkable stories of his research, travels, friends, colleagues, and scientific controversies that still roil today.--Peter Gleick, Science

Acclaimed as a public scientist and as a spokesperson on pressing environmental and equity issues, delivering his message from the classroom to 60 Minutes, Paul R. Ehrlich reflects on his life, including his love affair with his wife, Anne, his scientific research, his public advocacy, and his concern for global issues. Interweaving the range of his experiences--as an airplane pilot, a desegregationist, a proud parent--Ehrlich's insights are priceless on pressing issues such as biodiversity loss, overpopulation, depletion of resources, and deterioration of the environment. A lifelong advocate for women's reproductive rights, Ehrlich also helped to debunk scientific bias associating skin color and intelligence and warned some fifty years ago about a possible pandemic and the likely ecological consequences of a nuclear war.

This book is a vital contribution to literature focused on the human predicament, including problems of governance and democracy in the twenty-first century, and insight into the ecological and evolutionary science of our day. It is a must-read for anyone interested in understanding global change, our planet's wonders, and a scientific approach to the present existential threats to civilization.

Why do we behave the way we do? Biologist Paul Ehrlich suggests that although people share a common genetic code, these genes do not shout commands at us...at the very most, they whisper suggestions. He argues that human nature is not so much result of genetic coding; rather, it is heavily influenced by cultural conditioning and environmental factors. With personal anecdotes, a well-written narrative, and clear examples, Human Natures is a major work of synthesis and scholarship as well as a valuable primer on genetics and evolution that makes complex scientific concepts accessible to lay readers.

One of the most potentially disastrous consequences of global warming is likely to be the massive migration of displaced populations, including many of the world's poorest. As a place where a wealthy, heavily industrialized country is bordered directly by a struggling, preindustrial nation, the 2,000-mile United States-Mexican border provides a stark preview of the challenges we will face. Stereotyped thinking, based on racism or fear, will not solve these problems. The Golden Door is a sensitive exploration of a difficult situation, including background on Cuban, Salvadoran, and Haitian migration to the United States.

When we think of family, we most often think of our sisters and brothers, our cousins and grandparents, rather than our world family or even our community connections. We still identify with our differences more than our similarities, unless it's convenient to do otherwise. Here, two seasoned authors tackle the question of family and what it means to us now and how it might change to help us address the problems that affect us all. Using specific examples throughout the work, they present a unique approach to what it means to belong to one human family. Beginning with a consideration of how the family unit has begun to be defined by allegiances, by common ties and empathy, the authors then discuss the evolution of the family unit and how the 'us' vs. 'them' mentality gave way to a way of life that separated peoples rather than brought them together. They consider family values, how they arose, developed, were perverted or perfected to suit the family unit's needs, and the confusion that followed. Humanity on a Tightrope focuses on what families and family values are, and how they often create an 'us versus them' mentality that is at the root of many of today's most crucial problems from terrorism, racism, and war to the failure of humanity to come to grips with potentially lethal global environmental problems. The book underlines a basic element for solving the human predicament -- quickly spreading the domain of empathy. It takes a close look at how we can do that, building on the findings of both social and natural science and using tools ranging from brain imaging to the internet. It explains how civilization is unlikely to persist unless many more people learn to put themselves in the shoes of others to keep society balancing on the tightrope to sustainability - a tightrope suspended over the collapse of civilization.

In humanity's more than 100,000 year history, we have evolved from vulnerable creatures clawing sustenance from Earth to a sophisticated global society manipulating every inch of it. In short, we have become the dominant animal. Why, then, are we creating a world that threatens our own species? What can we do to change the current trajectory toward more climate change, increased famine, and epidemic disease?

Renowned Stanford scientists Paul R. Ehrlich and Anne H. Ehrlich believe that intelligently addressing those questions depends on a clear understanding of how we evolved and how and why we're changing the planet in ways that darken our descendants' future. The Dominant Animal arms readers with that knowledge, tracing the interplay between environmental change and genetic and cultural evolution since the dawn of humanity. In lucid and engaging prose, they describe how Homo sapiens adapted to their surroundings, eventually developing the vibrant cultures, vast scientific knowledge, and technological wizardry we know today.

But the Ehrlichs also explore the flip side of this triumphant story of innovation and conquest. As we clear forests to raise crops and build cities, lace the continents with highways, and create chemicals never before seen in nature, we may be undermining our own supremacy. The threats of environmental damage are clear from the daily headlines, but the outcome is far from destined. Humanity can again adapt--if we learn from our evolutionary past.

Those lessons are crystallized in The Dominant Animal. Tackling the fundamental challenge of the human predicament, Paul and Anne Ehrlich offer a vivid and unique exploration of our origins, our evolution, and our future.

Hope on Earth is the thought-provoking result of a lively and wide-ranging conversation between two of the world's leading interdisciplinary environmental scientists: Paul R. Ehrlich, whose book The Population Bomb shook the world in 1968 (and continues to shake it), and Michael Charles Tobias, whose over 40 books and 150 films have been read and/or viewed throughout the world. Hope on Earth offers a rare opportunity to listen in as these deeply knowledgeable and highly creative thinkers offer their takes on the most pressing environmental concerns of the moment.

Both Ehrlich and Tobias argue that we are on the verge of environmental catastrophe, as the human population continues to grow without restraint and without significant attempts to deal with overconsumption and the vast depletion of resources and climate problems it creates. Though their views are sympathetic, they differ in their approach and in some key moral stances, giving rise to a heated and engaging dialogue that opens up dozens of new avenues of exploration. They both believe that the impact of a human society on its environment is the direct result of its population size, and through their dialogue they break down the complex social problems that are wrapped up in this idea and attempts to overcome it, hitting firmly upon many controversial topics such as circumcision, religion, reproduction, abortion, animal rights, diet, and gun control. For Ehrlich and Tobias, ethics involve not only how we treat other people directly, but how we treat them and other organisms indirectly through our effects on the environment. University of California, Berkeley professor John Harte joins the duo for part of the conversation, and his substantial expertise on energy and climate change adds a crucial perspective to the discussion of the impact of population on global warming.

This engaging and timely book invites readers into an intimate conversation with some of the most eminent voices in science as they offer a powerful and approachable argument that the ethical and scientific issues involved in solving our environmental crisis are deeply intertwined, while offering us an optimistic way forward. Hope on Earth is indeed a conversation we should all be having.

The Bell Curve, The Moral Animal, The Selfish Gene -- these and a host of other books and articles have made a seemingly overwhelming case that our genes determine our behavior. Now, in a new book that is sure to stir controversy, one of the world's leading evolutionary biologists shows why most of those claims of genetic destiny cannot be true, and explains how the arguments often stem from a fundamental misunderstanding of evolution itself.

You can't change human nature, the saying goes. But you can, Stanford biologist Paul Ehrlich shows us in Human Natures, and in fact, evolution is the story of those changing natures. He makes a compelling case that human nature is not a single, unitary entity, but is as diverse as humanity itself, and that changes in culture and other environmental variations play as much of a role in human evolution as genetic changes. We simply don't have enough genes to specify behavior at the level that is often asserted.

Never has knowledge of our evolutionary past been more important to our future. Developing intelligent strategies for antibiotic use, pest control, biodiversity protection -- and even for establishing more equitable social arrangements -- all depend on understanding evolution and how it works. A hallmark of Human Natures is the author's ability to convey lucidly that understanding in the course of presenting an engrossing history of our species. Using personal anecdote, vivid example, and stimulating narrative, Ehrlich guides us through the thicket of controversies over what science can and cannot say about the influence of our evolutionary past on everything from race to religion, from sexual orientation to economic development.

A major work of synthesis and scholarship, Human Natures gives us the fruit of a lifetime's thought and research on evolution and environment by a modern master of scientific understanding. Ehrlich's innovative vision lights the way to a fresh view of human nature and evolution, bringing insight and clarity to urgent questions of where we are as a species, and where we may be headed.

Named a Notable Book for 2005 by the American Library Association, One with Nineveh is a fresh synthesis of the major issues of our time, now brought up to date with an afterword for the paperback edition. Through lucid explanations, telling anecdotes, and incisive analysis, the book spotlights the three elephants in our global living room-rising consumption, still-growing world population, and unchecked political and economic inequity-that together are increasingly shaping today's politics and humankind's future. One with Nineveh brilliantly puts today's political and environmental debates in a larger context and offers some bold proposals for improving our future prospect.

In this provocative book, the authors look at the interaction between population and food supply and offer a powerful and radical strategy for balancing human numbers with nutritional needs. Their proposals include improving the status of women, reducing racism and religious prejudice, reforming the agricultural system, and shrinking the growing gap between rich and poor.

Despite widespread public support for environmental protection, a backlash against environmental policies is developing. Fueled by outright distortions of fact and disregard for the methodology of science, this backlash appears as an outpouring of seemingly authoritative opinions by so-called experts in books, articles, and appearances on television and radio that greatly distort what is or is not known by environmental scientists. Through relentless repetition, the flood of anti-environmental sentiment has acquired an unfortunate aura of credibility, and is now threatening to undermine thirty years of progress in defining, understanding, and seeking solutions to global environmental problems.

In this hard-hitting and timely book, world-renowned scientists and writers Paul R. Ehrlich and Anne H. Ehrlich speak out against what they call the brownlash. Brownlash rhetoric, created by public relations spokespersons and a few dissident scientists, is a deliberate misstatement of scientific findings designed to support an anti-environmental world view and political agenda. As such, it is deeply disturbing to environmental scientists across the country. The agenda of brownlash proponents is rarely revealed, and the confusion and distraction its rhetoric creates among policymakers and the public prolong an already difficult search for realistic and equitable solutions to global environmental problems.

In Betrayal of Science and Reason, the Ehrlichs explain clearly and with scientific objectivity the empirical findings behind environmental issues including population growth, desertification, food production, global warming, ozone depletion, acid rain, and biodiversity loss. They systematically debunk revisionist truths such as:

• population growth does not cause environmental damage, and may even be beneficial
• humanity is on the verge of abolishing hunger; food scarcity is a local or regional problem and is not indicative of overpopulation
• there is no extinction crisis
• natural resources are superabundant, if not infinite
• global warming and acid rain are not serious threats to humanity
• stratospheric ozone depletion is a hoax
• risks posed by toxic substances are vastly exaggerated

The Ehrlichs counter the erroneous information and misrepresentation put forth by the brownlash, presenting accurate scientific information about current environmental threats that can be used to evaluate critically and respond to the commentary of the brownlash. They include important background material on how science works and provide extensive references to pertinent scientific literature. In addition, they discuss how scientists can speak out on matters of societal urgency yet retain scientific integrity and the support of the scientific community.

Betrayal of Science and Reason is an eye-opening look at current environmental problems and the fundamental importance of the scientific process in solving them. It presents unique insight into the sources and implications of anti-environmental rhetoric, and provides readers with a valuable means of understanding and refuting the feel-good fables that constitute the brownlash.
