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.

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.

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.

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.

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.

Renowned professor Michael B. McElroy leads a comprehensive examination of energy, including its history, use in the world today, and environmental consequences. Whether discussing the "oil shocks" of the 1970s, the current reliance on imported oil, or the growing buildup of carbon dioxide in the planet's atmosphere, it is clear that energy represents one of the world's most daunting challenges.

One woman's enlightening trek through the natural histories, cultural stories, and present perils of thirteen national monuments.

Over the course of 14 billion years, humanity has gained the ability not only to imagine the future, but to design and engineer it. Entertaining and profound, Future Rising by Dr Andrew Maynard, provides a highly original perspective on our relationship with the future. Written to be easy to pick up and hard to stop listening to, Future Rising starts at the big bang and traces a pathway along the emergence of intelligent life, through what makes humans uniquely capable of creating different futures, to the profound responsibilities that this comes with.

Since its inception, however, America’s public land system has been embroiled in controversy - caught in the push and pull between the desire to develop the valuable resources the land holds or conserve them. Alarmed by rising tensions over the use of these lands, hunter, angler, and outdoor enthusiast Mark Kenyon set out to explore the spaces involved in this heated debate, and learn firsthand how they came to be and what their future might hold.

Capitalism Is Past Its Sell-By Date explores capitalism’s accomplishments, its challenges, and the most profound effect of its success—overconsumption that is challenging the Earth’s ecosystems and inhabitants. Included is a comprehensive review of capitalism, an exploration of the implications of the exhaustion of the Earth’s resources, and an examination of growth. This book aims neither to praise nor to condemn capitalism, but to describe its current and future states of play to create a more proactive and productive conversation around our shared global future.

There are ninety thousand registered dams in the United States, fifty thousand of them classified as “major.” Nearly all of this infrastructure was built during a forty-year period, from 1932 to 1972, in an era of public investment and political consensus that seems inconceivable today. These incredible structures—sometimes called the American Pyramids—helped the country rebound from the Great Depression, brought water and electricity to enormous reaches, helped win World War II for the Allies, and became the basis for decades of prosperous stability.

Most of us give little thought to the hidden systems that bring us water and take it away when we’re done. But these underappreciated marvels of engineering face an array of challenges that cannot be solved without a fundamental change to our relationship with water.

The past fifteen thousand years--the entire span of human civilization--have witnessed dramatic sea level changes, which began with rapid global warming at the end of the Ice Age, when sea levels were more than 700 feet below modern levels. Over the next eleven millennia, the oceans climbed in fits and starts. These rapid changes had little effect on those humans who experienced them, partly because there were so few people on earth, and also because they were able to adjust readily to new coastlines.

“A palaeontological howdunnit…[Spying on Whales] captures the excitement of…seeking answers to deep questions in cetacean science.” —Nature Called “the best of science writing” (Edward O. Wilson) and named a best book by Popular Science, a dive into the secret lives of whales...

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.

The conditions that allowed humans to live on this earth are fragile, incredibly so. Climate variability has at times created new niches that humans or their ancestors could potentially exploit, and challenges that at times have spurred innovation. But there’s a relatively narrow envelope of climate variability within which human civilization remains viable. And our survival depends on conditions remaining within that range. In this book, renowned climate scientist Michael Mann will arm listeners with the knowledge necessary to appreciate the gravity of the unfolding climate crisis.

We are in the midst of an extinction event: the sixth mass extinction on Earth and one entirely caused by mankind. All species become extinct sooner or later, but we have accelerated that natural process several hundredfold, and now, it is happening right in front of our eyes. Extinction has a terrifying finality to it. And many species have already been lost to us forever; there is little we can do about that. What we can do, however, is reflect, remember, and ultimately acknowledge the unvarnished truth.
