Sand, iron, salt, oil, copper and lithium. The struggle for these tiny, magical materials has razed empires, demolished civilizations, fed our greed and our ingenuity for thousands of years. But the story is not over. We are often told we now live in a weightless world of information but in fact we dug more stuff out of the earth in 2017 than in all of human history before 1950. And it's getting worse. To make one bar of gold, we now have to dig 5,000 tons of earth. For every tonne of fossil fuels, we extract six tonnes of other materials - from sand to stone to wood to metal.

In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.

This audiobook explores how the discoveries within the Solar System and of exoplanets far beyond it come together to help us understand the habitability of Earth, and how these findings guide the search for exoplanets that could support life. The author highlights how, within two decades of the discovery of the first planets outside the Solar System in the 1990s, scientists concluded that planets are so common that most stars are orbited by them. The lives of exoplanets and their stars are inextricably interwoven.

Jeffrey W. Martz of the Denver Museum of Nature and Science is widely renowned for his expertise in the field of paleontology, a science that lies at the crossroads of biology and geology. Paleontologists seek to unearth and re-create life hundreds of millions of years old, and the work of paleontologists offers us detailed glimpses of the prehistoric world. These fascinating lectures delve into the techniques and processes of paleontologists while providing a better understanding of this often misunderstood science.

Humans depend on soil for 95 percent of global food production, yet let it erode at unsustainable rates. In the United States, China, and India, vast tracts of farmland will be barren of topsoil within this century. The combination of intensifying erosion caused by climate change and the increasing food needs of a growing world population is creating a desperate need for solutions to this crisis.

A day in the life of Carla Valentine - curator, pathology technician and 'death professional' - is not your average day. She spent 10 years training and working as an Anatomical Pathology Technologist: where the mortuary slab was her desk and that day's corpses her task list. Past Mortems tells Carla's stories of those years and investigates the body alongside our attitudes towards death - shedding light on what the living can learn from the dead and the toll the work can take on the living souls who carry it out.

Landscapes reflect and shape our behaviour. They make us who we are and bear witness to the shifting patterns of human life over the generations. Formed by a complex series of natural and human processes, they rarely yield their secrets readily. Bringing to bear a lifetime's digging, Francis Pryor delves into England's hidden urban and rural landscapes, from Whitby Abbey to the navvy camp at Risehill in Cumbria, from Tintagel to Tottenham's Broadwater Farm.

This original, topical and engaging book navigates the complex realm of forest restoration. It reveals how a nuanced approach is required – one that integrates the latest scientific advancements (for instance in microbial ecology, acoustic technology and epigenetics), Indigenous leadership and a holistic understanding of the interconnectedness of life within these vital ecosystems.

We have never had so much information at our fingertips, and yet most of us simply don't understand how our world really works. Professor Vaclav Smil is not a pessimist or an optimist, he is a scientist, and this book is a much-needed reality check on topics ranging from food production and nutrition, through energy and the environment, to globalisation and the future. For example, the carbon footprint of meat is well known, but did you know that the equivalent of five tablespoons of diesel fuel goes into the production of each greenhouse-grown, medium-size, supermarket-bought tomato?

All tequilas are mezcals; all mezcals are made from agaves; and every bottle of mezcal is the remarkable result of collaborations among agave entrepreneurs, botanists, distillers, beverage distributors, bartenders, and more. How these groups come together in this "spirits world" is the subject of this fascinating new book by the acclaimed ethnobotanist Gary Paul Nabhan and the pioneering restauranteur David Suro Piñera.

In one of the most inventive travel books in years, Ina Caro invites listeners on 25 one-day train trips that depart from Paris and transport us back through 700 years of French history. Whether taking us to Orléans to evoke the visions of Joan of Arc or to the Place de la Concorde to witness the beheading of Marie Antoinette, Caro animates history with her lush descriptions of architectural splendors and tales of court intrigue. "[An] enchanting travelogue" (Publishers Weekly), Paris to the Past has become one of the classic guidebooks of our time.

Twelve Trees introduces us to a dozen species of trees that epitomize the challenges facing the planet, and the ways that scientists and others are working with a growing sense of urgency to save them. Scientists, ethnobotanists, indigenous peoples, and collectives of all kinds are studying trees and their workings, using a host of new tools, to learn how trees function individually and collectively, and why they do what they do.

On an antique map in Oxford's Bodleian Library, a faint red line threading through towns and villages between Southampton and Canterbury suggests a significant, though long-forgotten, road. Renamed the Old Way, medieval pilgrims are thought to have travelled this route to reach the celebrated shrine of Thomas Becket. Described as England's Camino, this long-distance footpath carves through one of the nation's most iconic landscapes—one that links prehistoric earthworks, abandoned monasteries, Saxon churches, ruined castles and historic seaports.

From the secret fossils of London to the three-billion-year-old rocks of the Scottish Highlands, and from state-of-the-art Californian laboratories to one of the world's most dangerous volcanic complexes hidden beneath the green hills of western Naples, set out on an adventure to those parts of the world where the Earth's life-story is written into the landscape. Helen Gordon turns a novelist's eye on the extraordinary scientists who are piecing together this planetary drama.

The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

Madagascar is a place of change. A biodiversity hotspot and the fourth largest island on the planet, it has been home to a spectacular parade of animals, from giant flightless birds and giant tortoises on the ground, to agile lemurs leaping through the treetops. Some species live on, many have vanished in the distant or recent past. Over vast stretches of time, Madagascar’s forests have expanded and contracted in response to shifting climates and the hand of people is clear in changes during the last 1,000 years or so.

Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. We have hunted them for thousands of years and scratched their icons into our mythologies. They simultaneously fill us with waves of terror, awe and affection - yet we know hardly anything about them. Whales tend to enter our awareness only when they die, struck by a ship or stranded in the surf. They evolved from land-roaming, doglike creatures into animals that move like fish and breathe like us and can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Yet despite centuries of observing whales, we know little about their evolutionary past.

More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans.

Bears have always held a central place in our collective memory, from Indigenous folklore and Greek mythology to nineteenth-century fairytales and the modern toy shop. But as humans and bears come into ever-closer contact, our relationship nears a tipping point. Today, most of the eight remaining bear species are threatened with extinction. Some, such as the panda bear and the polar bear, are icons of the natural world; others, such as the spectacled bear and the sloth bear, are far less known.

It is rare for life to change Earth, yet three organisms have profoundly transformed our planet over the long course of its history. Elemental reveals how microbes, plants, and people used the fundamental building blocks of life to alter the climate, and with it, the trajectory of life on Earth in the past, present, and future. Taking listeners from the deep geologic past to our current era of human dominance, Stephen Porder focuses on five of life’s essential elements—hydrogen, oxygen, carbon, nitrogen, and phosphorus.
