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.

    Ultimately, the history of these challenges tells the story of humanity itself. Through an unforgettable cast of characters, Pulitzer Prize-winning author Richard Rhodes explains how wood gave way to coal and coal made room for oil, as we now turn to natural gas, nuclear power, and renewable energy. Rhodes looks back on five centuries of progress, through such influential figures as Queen Elizabeth I, King James I, Benjamin Franklin, Herman Melville, John D. Rockefeller, and Henry Ford. In Energy, Rhodes highlights the successes and failures that led to each breakthrough in energy production; from animal and waterpower to the steam engine, from internal-combustion to the electric motor. He addresses how we learned from such challenges, mastered their transitions, and capitalized on their opportunities. Rhodes also looks at the current energy landscape, with a focus on how wind energy is competing for dominance with cast supplies of coal and natural gas. He also addresses the specter of global warming, and a population hurtling towards ten billion by 2100. Human beings have confronted the problem of how to draw life from raw material since the beginning of time. Each invention, each discovery, each adaptation brought further challenges, and through such transformations, we arrived at where we are today. In Rhodes’s singular style, Energy details how this knowledge of our history can inform our way tomorrow.

    What is it like to try to heal the body when the mind is under attack? In this book, Dr. Allan Ropper and Brian Burrell take the reader behind the scenes at Harvard Medical School's neurology unit to show how a seasoned diagnostician faces down bizarre, life-altering afflictions. Like Alice in Wonderland, Dr. Ropper inhabits a world where absurdities abound:• A figure skater whose body has become a ticking time-bomb • A salesman who drives around and around a traffic rotary, unable to get off • A college quarterback who can't stop calling the same play • A child molester who, after falling on the ice, is left with a brain that is very much dead inside a body that is very much alive • A mother of two young girls, diagnosed with ALS, who has to decide whether a life locked inside her own head is worth livingHow does one begin to treat such cases, to counsel people whose lives may be changed forever? How does one train the next generation of clinicians to deal with the moral and medical aspects of brain disease? Dr. Ropper and his colleague answer these questions by taking the reader into a rarified world where lives and minds hang in the balance.

    Astrophysicist Adam Frank traces the question of alien life and intelligence from the ancient Greeks to the leading thinkers of our own time, and shows how we as a civilization can only hope to survive climate change if we recognize what science has recently discovered: that we are just one of ten billion trillion planets in the Universe, and it’s highly likely that many of those planets hosted technologically advanced alien civilizations. What’s more, each of those civilizations must have faced the same challenge of civilization-driven climate change.Written with great clarity and conviction, Light of the Stars builds on the inspiring work of pioneering scientists such as Frank Drake and Carl Sagan, whose work at the dawn of the space age began building the new science of astrobiology; Jack James, the Texas-born engineer who drove NASA’s first planetary missions to success; Vladimir Vernadsky, the Russian geochemist who first envisioned the Earth’s biosphere; and James Lovelock and Lynn Margulis, who invented Gaia theory. Frank recounts the perilous journey NASA undertook across millions of miles of deep space to get its probes to Venus and Mars, yielding our first view of the cosmic laws of planets and climate that changed our understanding of our place in the universe.Thrilling science at the grandest of scales, Light of the Stars explores what may be the largest question of all: What can the likely presence of life on other worlds tell us about our own fate?

    This brief introduction shows how psycholinguistic research can act as a window to the workings of the human mind and the study of consciousness.

    But in fact, between animal welfare and conservation science there exists a space of underexamined and unresolved tension: wildness itself. When is it right to capture or feed wild animals for the good of their species? How do we balance the rights of introduced species with those already established within an ecosystem? Can hunting be ecological? Are any animals truly wild on a planet that humans have so thoroughly changed? No clear guidelines yet exist to help us resolve such questions.Transporting readers into the field with scientists tackling these profound challenges, Emma Marris tells the affecting and inspiring stories of animals around the globe-from Peruvian monkeys to Australian bilbies, rare Hawai'ian birds to majestic Oregon wolves. And she offers a companionable tour of the philosophical ideas that may steer our search for sustainability and justice in the non-human world. Revealing just how intertwined animal life and human life really are, Wild Souls will change the way we think about nature-and our place within it.

    Healthy soil is teeming with life — not just earthworms and insects, but a staggering multitude of bacteria, fungi, and other microorganisms. When we use chemical fertilizers, we injure the microbial life that sustains healthy plants, and thus become increasingly dependent on an arsenal of artificial substances, many of them toxic to humans as well as other forms of life. But there is an alternative to this vicious circle: to garden in a way that strengthens, rather than destroys, the soil food web — the complex world of soil-dwelling organisms whose interactions create a nurturing environment for plants. By eschewing jargon and overly technical language, the authors make the benefits of cultivating the soil food web available to a wide audience, from devotees of organic gardening techniques to weekend gardeners who simply want to grow healthy, vigorous plants without resorting to chemicals.

    Who would have guessed that all of our sexual and social behavior, and even our physical appearance, could be attributed to what our tiny unseen reproductive cells are doing? But that's Quirk's thesis in this highly entertaining book from an Average Guy that's a fun read full of a-ha! moments for scientists and civilians alike. Learn facts about cheating you'll never see on "Jerry Springer," like how unfaithful females actually change the biology of their mates. Discover why most sperm couldn't care less if they never saw an egg, what makes men yell "woo!" in a feminine falsetto--very similar to the mating cry of the Siamang gibbon--and, most important, the surprising answer on what to wear to attract that alpha mate.

    Accompanied by illustrations, maps, diagrams and step-by-step instructions, this manual will be essential reading for those interested in protecting themselves, their families and society at large from the living dead.

    That’s right: growing more mushrooms may be the best thing we can do to save the environment, and in this groundbreaking text from mushroom expert Paul Stamets, you’ll find out how. The basic science goes like this: Microscopic cells called “mycelium”--the fruit of which are mushrooms--recycle carbon, nitrogen, and other essential elements as they break down plant and animal debris in the creation of rich new soil. What Stamets has discovered is that we can capitalize on mycelium’s digestive power and target it to decompose toxic wastes and pollutants (mycoremediation), catch and reduce silt from streambeds and pathogens from agricultural watersheds (mycofiltration), control insect populations (mycopesticides), and generally enhance the health of our forests and gardens (mycoforestry and myco-gardening).  In this comprehensive guide, you’ll find chapters detailing each of these four exciting branches of what Stamets has coined “mycorestoration,” as well as chapters on the medicinal and nutritional properties of mushrooms, inoculation methods, log and stump culture, and species selection for various environmental purposes. Heavily referenced and beautifully illustrated, this book is destined to be a classic reference for bemushroomed generations to come.
