The secret stories of what leaves mean - and what they mean to us. Leaves are one of nature's marvels. We watch them turn red in Autumn, make medicine from them, invent folklore around them, and mark the passing of time by them. But how do they grow? Why are they the shapes they are? What makes...

Once upon a time, a burnt-out Claire Dunn spent a year living off the grid in a wilderness survival program. Yet love and the possibilities of human connection drew her back to the city, where she soon found herself as overscheduled, addicted to her phone and lost in IKEA as everyone else. Given all the city offered - comfort, convenience, community and opportunity - she wanted to stay. But to do so, she'd have to learn how to rewild her own urban soul. Now, Claire swims in city rivers, forages in the suburbs and explores many other practices to connect to the world around her.

In 1969, five young men from Montana set out to accomplish what no one had before: to scale the sheer north face of Mt. Cleveland, Glacier National Park’s tallest mountain, in winter. Two days later tragedy struck: They were buried in an avalanche so deep that their bodies would not be discovered until the following June. The White Death is the riveting account of that fated climb and of the breathtakingly heroic rescue attempt that ensued.

Humanity has used asphalt for thousands of years. This humble hydrocarbon may have glued the first arrowhead to the first shaft, but the changes wrought by this material are most dramatic since its emergence as pavement. Since the 1920s the automobile and blacktop have allowed unprecedented numbers of Americans to experience the beauty of their continent from the Adirondacks to the Rockies and beyond, to Big Sur and the Pacific Coast Highway.

For nearly a decade, Palley has been on the frontline of fire. He has witnessed homeowners on the worst day of their lives. He’s seen puddles of aluminum where cars were once parked. He’s watched as 150-foot walls of flame cascaded down mountainsides and crashed into the Pacific Ocean. And he’s captured, time and again, the tireless commitment of firefighters as they work to save lives and homes, in terrain where fire always seems to have the upper hand.

How deep do sharks swim? Have more people been into space than the deep ocean? And what effect are we having on the health of our seas? In Ask an Ocean Explorer, marine biologist of over 20 years and advisor for the BBC's Blue Planet II, Dr Jon Copley, explains the science and wonder of the deep ocean.

Desde las junglas húmedas de Costa Rica hasta el fétido entorno de las zonas rebeldes del sur de Sudán, Carl Zimmer nos guía a través de un viaje por el universo de los parásitos, un mundo en el que habitamos sin ser conscientes. Así nos descubre no solo la forma de vida más exitosa del planeta, sino aquella que da forma a los ecosistemas y es el motor de la evolución. Zimmer nos muestra, pues, cuánto han evolucionado estos bichos, y relata la aterradora facilidad con que pueden devorar a quien los hospeda, e incluso controlar su conducta.

Abdulrahman Zeitoun fue uno de los héroes anónimos del Katrina. Durante los días que siguieron al paso del huracán, navegó por las calles inundadas de Nueva Orleans en una vieja canoa ayudando a sus vecinos. Una semana más tarde fue arrestado y acusado de pertenecer a Al Qaeda. Esta es la historia real de Zeitoun. Esta es la historia de Nueva Orleans.

Never have so many undertaken such a widespread, hurried attempt to remake the world. Predictably, our hubris has led to unintended—and sometimes disastrous—consequences. Over the Seawall tells us the stories behind these unintended consequences and the fixes that can do more harm than good. From seawalls in coastal Japan, to the reengineered waters in the Ganges River Delta, to the artificial ribbon of water supporting both farms and urban centers in parched Arizona, Stephen Robert Miller traces the histories of engineering marvels that were once deemed too smart and too big to fail.

The Man Who Thought He Owned Water is author Tershia d’Elgin’s fresh take on the gravest challenge of our time—how to support urbanization without killing ourselves in the process. The gritty story of her family’s experience with water rights on its Colorado farm provides essential background about American farms, food, and water administration in the West in the context of growing cities and climate change.

You don’t have to be an animal rights activist to take an interest in how we treat other creatures. All of us, with few exceptions, use animals in some way: for food, research, recreation, and companionship. In Britain, we eat around a billion chickens every year, while 60 percent of all mammals on Earth, by biomass, are now livestock.

Lakes might be the most misunderstood bodies of water on earth. And while they may seem commonplace, without lakes our world would never be the same. In this revealing look at these lifegiving treasures, John Richard Saylor shows us just how deep our connection to still waters run.

The next fertile undiscovered frontier of science is the study of how the individual (you) naturally inhabit this universe. This topic speaks to the really interesting question of how any living individual came to be where you are in the form that you are.

Giant earthquakes and tsunamis devastate western Oregon every 300 to 600 years. The last one hit in 1700, so we're due anytime. This informative, entertaining book tells the stories of Oregon's past floods, fires, and eruptions - including the Vanport Flood, the eruption of Mt. St. Helens, and the Columbus Day Windstorm. Then it investigates the cycles behind our natural disasters and takes a look at what may happen when the next "Big One" strikes.

Bees are like oxygen: ubiquitous, essential, and, for the most part, unseen. While we might overlook them, they lie at the heart of relationships that bind the human and natural worlds. In Buzz, the beloved Thor Hanson takes us on a journey that begins 125 million years ago, when a wasp first dared to feed pollen to its young. From honeybees and bumbles to lesser-known diggers, miners, leafcutters, and masons, bees have long been central to our harvests, our mythologies, and our very existence. They've given us sweetness and light, the beauty of flowers, and as much as a third of the foodstuffs we eat. And, alarmingly, they are at risk of disappearing.

American engineers have done astounding things to bend the Mississippi River to their will: forcing one of its tributaries to flow uphill, transforming over 1000 miles of roiling currents into a placid staircase of water, and wresting the lower half of the river apart from its floodplain. American law has aided and abetted these feats. But despite our best efforts, so-called "natural disasters" continue to strike the Mississippi basin as raging floodwaters decimate waterfront communities and abandoned towns literally crumble into the Gulf of Mexico.

Over the past few years, devastating tsunamis off the coast of the Indian Ocean have killed hundreds of thousands of people. Even more alarmingly, scientists predict that these tsunamis, as well as a series of earthquakes and volcanic eruptions, will be striking with even greater frequency and may eventually threaten Hawaii, California, and Oregon.

In recent years, scientists have hypothesized life-forms that can only be called "weird": organisms that live off acid rather than water, microbes that thrive at temperatures and pressure levels so extreme that their cellular structures should break down, perhaps even organisms that reproduce without DNA. Some of these strange life-forms, unrelated to all life we know, might be nearby: on rock surfaces in the American southwest, hydrothermal vents on the ocean floor, or even in our own bodies. Some, stranger still, might live in Martian permafrost, swim in the dark oceans of Jupiter's moons, or survive in the exotic ices on comets.

While examining the history of our planet and actively exploring our present environment, science journalist Michael Tennesen describes what life on Earth could look like after the next mass extinction.

In Slime we'll meet the algae innovators working toward a sustainable future: from seaweed farmers in South Korea, to scientists using it to clean the dead zones in our waterways, to the entrepreneurs fighting to bring algae fuel and plastics to market. Ruth Kassinger takes listeners on an around-the-world, behind-the-scenes, and into-the-kitchen tour. Whether you thought algae was just the gunk in your fish tank or you eat seaweed with your oatmeal, Slime will delight and amaze with its stories of the good, the bad, and the up-and-coming.
