To mark the event, National Geographic magazine commissioned seven articles that explore the fascinating issues—including demographics, food security, climate change, fertility trends, managing biodiversity—surrounding this topic, which are collected for the first time in this special ebook.   Envi­ronment editor Robert Kunzig starts by sketching out a natural history of population. The issues associated with population growth seem endless: poverty, food and water supply, world health, climate change, deforestation, fertility rates, and more. In additional chapters Elizabeth Kolbert explores a new era—the “Anthropocene,” or the age of man—defined by our massive impact on the planet, which will endure long after our cities have crumbled; and takes us to the Mediterranean, where she delves into issues associated with increasing ocean acidification. In Bangladesh, Don Belt explores how the people of this crowded region can teach us about adapting to rising sea levels. In “Food Ark” we travel deep within the earth and around the globe to explore the seed banks that are preserving the variety of food species we may need to increase food production on an increasingly crowded planet. In Brazil, Cynthia Gournay explores the phenomenon of “Machisma” and shows how a mix of female empowerment and steamy soap operas helped bring down Brazil’s fertility rate and stoke its vibrant economy. Additionally we explore threats to biodiversity, and the return of cities—which may be the solution to many of our population woes. Join National Geographic on this incredible journey to explore our rapidly growing planet.

    More than 200 million years ago, geological forces split apart the continents. Isolated from each other, the two halves of the world developed radically different suites of plants and animals. When Christopher Columbus set foot in the Americas, he ended that separation at a stroke. Driven by the economic goal of establishing trade with China, he accidentally set off an ecological convulsion as European vessels carried thousands of species to new homes across the oceans. The Columbian Exchange, as researchers call it, is the reason there are tomatoes in Italy, oranges in Florida, chocolates in Switzerland, and chili peppers in Thailand. More important, creatures the colonists knew nothing about hitched along for the ride. Earthworms, mosquitoes, and cockroaches; honeybees, dandelions, and African grasses; bacteria, fungi, and viruses; rats of every description—all of them rushed like eager tourists into lands that had never seen their like before, changing lives and landscapes across the planet. Eight decades after Columbus, a Spaniard named Legazpi succeeded where Columbus had failed. He sailed west to establish continual trade with China, then the richest, most powerful country in the world. In Manila, a city Legazpi founded, silver from the Americas, mined by African and Indian slaves, was sold to Asians in return for silk for Europeans. It was the first time that goods and people from every corner of the globe were connected in a single worldwide exchange. Much as Columbus created a new world biologically, Legazpi and the Spanish empire he served created a new world economically.As Charles C. Mann shows, the Columbian Exchange underlies much of subsequent human history. Presenting the latest research by ecologists, anthropologists, archaeologists, and historians, Mann shows how the creation of this worldwide network of ecological and economic exchange fostered the rise of Europe, devastated imperial China, convulsed Africa, and for two centuries made Mexico City—where Asia, Europe, and the new frontier of the Americas dynamically interacted—the center of the world. In such encounters, he uncovers the germ of today’s fiercest political disputes, from immigration to trade policy to culture wars.In 1493, Charles Mann gives us an eye-opening scientific interpretation of our past, unequaled in its authority and fascination

    Montgomery heard a local story about a great flood that bore a striking similarity to Noah's Flood. Intrigued, Montgomery began investigating the world's flood stories and, drawing from historic works by theologians, natural philosophers, and scientists, discovered the counter-intuitive role Noah's Flood played in the development of both geology and creationism. Steno, the grandfather of geology, even invoked the Flood in laying geology's founding principles based on his observations of northern Italian landscapes. Centuries later, the founders of modern creationism based their irrational view of aglobal flood on a perceptive critique of geology. With an explorer's eye and a refreshing approach to both faith and science, Montgomery takes readers on a journey across landscapes and cultures. In the process we discover the illusive nature of truth, whether viewed through the lens of science or religion, and how it changed through history and continues changing, even today.

    In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life.We have always been fish eaters, from the dawn of civilization, but in the last twenty years we have transformed the oceans beyond recognition. Putting our exploitation of the seas into historical context, Roberts offers a devastating account of the impact of modern fishing techniques, pollution, and climate change, and reveals what it would take to steer the right course while there is still time. Like Four Fish and The Omnivore’s Dilemma, The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.

    They distill more than 20 years of research and first-hand accounts from the most biodiverse ecosystems on Earth into straightforward principles and guidance for confronting our culture of hyper-novelty.For evolutionary biologists Heather Heying and Bret Weinstein, the cause of our woes is clear: the modern world is out of sync with our ancient brains and bodies. We evolved to live in clans, but today most people don't even know their neighbors' names. Differences between the sexes once served a necessary evolutionary purpose, but today many dismiss the concept of biological sex as offensive. The cognitive dissonance spawned by trying to live in a society we're not built for is killing us.

    As swiftly as it came, it disappeared, leaving no trace. Over the four decades since, Ebola has emerged sporadically, each time to devastating effect. It can kill up to 90 percent of its victims. In between these outbreaks, it is untraceable, hiding deep in the jungle. The search is on to find Ebola’s elusive host animal. And until we find it, Ebola will continue to strike. Acclaimed science writer and explorer David Quammen first came near the virus while he was traveling in the jungles of Gabon, accompanied by local men whose village had been devastated by a recent outbreak. Here he tells the story of Ebola—its past, present, and its unknowable future.Extracted from Spillover by David Quammen, updated and with additional material.

    Today there is just one. Us. Homo sapiens. How did our species succeed in the battle for dominance? Why did our foraging ancestors come together to create cities and kingdoms? How did we come to believe in gods, nations and human rights; to trust money, books and laws; and to be enslaved by bureaucracy, timetables and consumerism? And what will our world be like in the millennia to come? In Sapiens, Dr Yuval Noah Harari spans the whole of human history, from the very first humans to walk the earth to the radical – and sometimes devastating – breakthroughs of the Cognitive, Agricultural and Scientific Revolutions. Drawing on insights from biology, anthropology, paleontology and economics, he explores how the currents of history have shaped our human societies, the animals and plants around us, and even our personalities. Have we become happier as history has unfolded? Can we ever free our behaviour from the heritage of our ancestors? And what, if anything, can we do to influence the course of the centuries to come? Bold, wide-ranging and provocative, Sapiens challenges everything we thought we knew about being human: our thoughts, our actions, our power ... and our future.

    Born and raised in a small town, they enjoy a close relationship, though each has her own tastes and personality. But the Hensels also share a body. Their two heads sit side-by-side on a single torso, with two arms and two legs. They have not only survived, but have developed into athletic, graceful young women. And that, writes Mark S. Blumberg, opens an extraordinary window onto human development and evolution.In Freaks of Nature, Blumberg turns a scientist's eye on the oddities of nature, showing how a subject once relegated to the sideshow can help explain some of the deepest complexities of biology. Why, for example, does a two-headed human so resemble a two-headed minnow? What we need to understand, Blumberg argues, is that anomalies are the natural products of development, and it is through developmental mechanisms that evolution works. Freaks of Nature induces a kind of intellectual vertigo as it upends our intuitive understanding of biology. What really is an anomaly? Why is a limbless human a freak, but a limbless reptile-a snake-a successful variation?What we see as deformities, Blumberg writes, are merely alternative paths for development, which challenge both the creature itself and our ability to fit it into our familiar categories. Rather than mere dead-ends, many anomalies prove surprisingly survivable-as in the case of the goat without forelimbs that learned to walk upright. Blumberg explains how such variations occur, and points to the success of the Hensel sisters and the goat as examples of the extraordinary flexibility inherent in individual development.In taking seriously a subject that has often been shunned as discomfiting and embarrassing, Mark Blumberg sheds new light on how individuals-and entire species-develop, survive, and evolve.

    I know tomorrow.” This inscription in Tutankhamun’s tomb summarizes The Fifth Beginning. Here, archaeologist Robert L. Kelly explains how the study of our cultural past can predict the future of humanity.   In an eminently readable style, Kelly identifies four key pivot points in the six-million-year history of human development: the emergence of technology, culture, agriculture, and the state. In each example, the author examines the long-term processes that resulted in a definitive, no-turning-back change for the organization of society. Kelly then looks ahead, giving us evidence for what he calls a fifth beginning, one that started about AD 1500. Some might call it “globalization,” but the author places it in its larger context: a five-thousand-year arms race, capitalism’s global reach, and the cultural effects of a worldwide communication network.   Kelly predicts that the emergent phenomena of this fifth beginning will include the end of war as a viable way to resolve disputes, the end of capitalism as we know it, the widespread shift toward world citizenship, and the rise of forms of cooperation that will end the near-sacred status of nation-states. It’s the end of life as we have known it. However, the author is cautiously optimistic: he dwells not on the coming chaos, but on humanity’s great potential.

    In Denialism, New Yorker staff writer Michael Specter reveals that Americans have come to mistrust institutions and especially the institution of science more today than ever before. For centuries, the general view had been that science is neither good nor bad—that it merely supplies information and that new information is always beneficial. Now, science is viewed as a political constituency that isn’t always in our best interest. We live in a world where the leaders of African nations prefer to let their citizens starve to death rather than import genetically modified grains. Childhood vaccines have proven to be the most effective public health measure in history, yet people march on Washington to protest their use. In the United States a growing series of studies show that dietary supplements and “natural” cures have almost no value, and often cause harm. We still spend billions of dollars on them. In hundreds of the best universities in the world, laboratories are anonymous, unmarked, and surrounded by platoons of security guards—such is the opposition to any research that includes experiments with animals. And pharmaceutical companies that just forty years ago were perhaps the most visible symbol of our remarkable advance against disease have increasingly been seen as callous corporations propelled solely by avarice and greed. As Michael Specter sees it, this amounts to a war against progress. The issues may be complex but the choices are not: Are we going to continue to embrace new technologies, along with acknowledging their limitations and threats, or are we ready to slink back into an era of magical thinking? In Denialism, Specter makes an argument for a new Enlightenment, the revival of an approach to the physical world that was stunningly effective for hundreds of years: What can be understood and reliably repeated by experiment is what nature regarded as true. Now, at the time of mankind’s greatest scientific advances—and our greatest need for them—that deal must be renewed.

    If you read one book on human origins, this should be it' Ian Morris, author of Why the West Rules - For Now 'The who, what, where, when and how of human evolution, from one of the world's experts on the dating of prehistoric fossils' Steve Brusatte, author of The Rise and Fall of the Dinosaurs50,000 years ago, we were not the only species of human in the world. There were at least four others, including the Neanderthals, Homo floresiensis, Homo luzonesis and the Denisovans. At the forefront of the latter's ground-breaking discovery was Oxford Professor Tom Higham. In The World Before Us, he explains the scientific and technological advancements - in radiocarbon dating and ancient DNA, for example - that allowed each of these discoveries to be made, enabling us to be more accurate in our predictions about not just how long ago these other humans lived, but how they lived, interacted and live on in our genes today. This is the story of us, told for the first time with its full cast of characters.'The application of new genetic science to pre-history is analogous to how the telescope transformed astronomy. Tom Higham brings us to the frontier of recent discoveries with a book that is both gripping and fun' Paul Collier, author of The Bottom Billion'This exciting book shows that we now have a revolutionary new tool for reconstructing the human past: DNA from minute pieces of tooth and bone, and even from the dirt on the floor of caves' David Abulafia, author of The Boundless Sea'The remarkable new science of palaeoanthropology, from lab bench to trench' Rebecca Wragg Sykes, author of Kindred'Higham's thrilling account makes readers feel as if they were participating themselves in the extraordinary series of events that in the last few years has revealed our long-lost cousins' David Reich, author of Who We Are and How We Got Here'A brilliant distillation of the ideas and discoveries revolutionising our understanding of human evolution' Chris Gosden, author of The History of Magic

    The Science of Evolution. From both, Richard Dawkins weaves a fascinating and beautifully illustrated account of how nature and humans have learned to overcome the pull of gravity and take to the skies.Do you sometimes dream you can fly like a bird? Gliding effortlessly above the treetops, soaring and swooping, playing and dodging through the third dimension. Computer games, virtual reality headsets, and some drugs can lift our imagination and fly us through fabled, magical spaces. But it's not the real thing. No wonder some of the past's greatest minds, including Leonardo da Vinci's, have yearned for flying machines and struggled to design them.Flights of Fancy is a book about flying – all the different ways of defying gravity that have been discovered by humans over the centuries and by other animals over the millions of years, from the mythical Icarus, to the sadly extinct but magnificent bird Argentavis magnificens, to the Wright Flyer and the 747. But it also means flights of digression into more general ideas and principles that take off from a discussion about actual flight.Fascinating and elegantly written, this is a unique collaboration between one of the world's leading zoologists and a talented artist, and perfect for enquiring teenage minds.

    He shows how oxygen underpins the origin of biological complexity, the birth of photosynthesis, the sudden evolution of animals, the need for two sexes, the accelerated aging of cloned animals like Dolly the sheep, and the surprisingly long lives of bats and birds. Drawing on this grand evolutionary canvas, Oxygen offers fresh perspectives on our own lives and deaths, explaining modern killer diseases, why we age, and what we can do about it. Advancing revelatory new ideas, following chains of evidence, the book ranges through many disciplines, from environmental sciences to molecular medicine. The result is a captivating vision of contemporary science and a humane synthesis of our place in nature. This remarkable book will redefine the way we think about the world.
