Si la historia de la Tierra se redujera a un año, nuestra especie surgiría en los últimos treinta minutos. Pero la vida ha existido durante 3.700 millones de años, la mayor parte de la historia de nuestro planeta y más de una cuarta parte de la edad del universo. ¿Qué hicieron esos organismos durante todo este tiempo?

Sixty-six million years ago the dinosaurs were wiped from the face of the earth. Today a new generation of dinosaur hunters, armed with cutting-edge technology, is piecing together the complete story of how the dinosaurs created a hugely successful empire that lasted for around 150 million years.

Even if we've never had direct contact with one, we will have seen one, or at the very least, heard one. For those of us who live in the Western world, it is more than likely that one sleeps in our house, possibly even on our bed. I'm talking, of course, of the dog. Yet, this animal, which lives alongside 500 million of us all over the world - as an invaluable partner and a trusted confidant - presents us with one great unsolved mystery: how did this relationship - the most complex and enduring of any between human and animal - start in the first place?

For the last three billion years or so, life on Earth was shaped by natural forces. Evolution tended to happen slowly, with species crafted across millennia. Then, a few hundred thousand years ago, along came a bolshie, big-brained, bipedal primate we now call Homo sapiens, and with that, the Earth’s natural history came to an abrupt end. We are now living through the post-natural phase, where humans have become the leading force shaping evolution. This audiobook considers the many ways that we’ve altered the DNA of living things and changed the fate of life on earth.

Moral Ground brings together the testimony of over eighty visionaries, theologians and religious leaders, scientists, elected officials, business leaders, naturalists, activists, and writers to present a diverse and compelling call to honor our individual and collective moral responsibility to our planet. In the face of environmental degradation and global climate change, scientific knowledge alone does not tell us what we ought to do.

The most recent research tells us that seaweed is one possible solution for our future on the planet. It could feed human beings, reduce plastic pollution, absorb enough carbon to cool the atmosphere, reconstruct generative ecosystems, treat certain illnesses that are incurable today, replace land livestock farming that exhausts the environment, and give jobs to coastal populations. The seaweed revolution is a hope for tomorrow!

Climate science can seem dense, remote, and abstract. But through the lens of this one tree, it becomes immediate and intimate. In Witness Tree, environmental reporter Lynda V. Mapes takes us through her year living with one red oak at the Harvard Forest. We learn about carbon cycles and leaf physiology but also experience the seasons as people have for centuries, watching for each new bud and listening for each new bird and frog call in spring.

They are trees of life and trees of knowledge. They are wish-fulfillers, rain forest royalty, more precious than gold. They are the fig trees, and they have affected humanity in profound but little-known ways. Gods, Wasps and Stranglers tells their amazing story. Fig trees fed our prehuman ancestors, influenced diverse cultures, and played key roles in the dawn of civilization.

In this book, Adams’ self-proclaimed favourite of his own works, the pair encounter animals in imminent peril: the giant Komodo dragon of Indonesia, the lovable kakapo of New Zealand, the blind river dolphins of China, the white rhinos of Zaire, the rare birds of Mauritius island in the Indian Ocean and the alien-like aye-aye of Madagascar. Inimitably witty and poignant, Last Chance to See is both a celebration of our most extraordinary creatures and a warning about what we have to lose if we do not act soon.

Beavers, those icons of industriousness, have been gnawing down trees, building dams, shaping the land, and creating critical habitat in North America for at least a million years. Once one of the continent's most ubiquitous mammals, they ranged from the Atlantic to the Pacific, and from the Rio Grande to the edge of the northern tundra. Wherever there was wood and water, there were beavers - 60 million (or more) - and wherever there were beavers, there were intricate natural communities that depended on their activities.

It's no secret that our planet is in crisis. Environmental threats such as climate change, pollution, habitat loss, and land degradation threaten the survival of thousands of plant and animal species. In 100 Heartbeats, Jeff Corwin provides an urgent portrait of the wildlife teetering on the brink. From the forests slipping away beneath the stealthy paws of the Florida panther, to the giant panda’s plight to climb ever higher in the mountains of China, Corwin takes you on a global tour to witness firsthand the critical state of our natural world.

We live at a time in which scientists race to reanimate extinct beasts, our most essential ecosystems require monumental engineering projects to survive, chicken breasts grow in test tubes, and multinational corporations conspire to poison the blood of every living creature. No rock, leaf, or cubic foot of air on Earth has escaped humanity's clumsy signature. The old distinctions - between natural and artificial, dystopia and utopia, science fiction and science fact - have blurred, losing all meaning. We inhabit an uncanny landscape of our own creation.

Our insatiable demand for animals - for jewelry, pets, medicine, meat, trophies, and fur - is driving a worldwide poaching epidemic, threatening the continued existence of countless species. Rachel Nuwer, an award-winning science journalist with a background in ecology, takes listeners on a narrative journey to the front lines of the trade: to killing fields in Africa, traditional medicine black markets in China, and wild meat restaurants in Vietnam. Through exhaustive first-hand reporting that took her to 10 countries, Nuwer explores the forces currently driving the demand.

Over the last half a billion years, there have been five mass extinctions of life on earth. Scientists around the world are currently monitoring the sixth, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. Elizabeth Kolbert combines brilliant field reporting, the history of ideas and the work of geologists, botanists and marine biologists to tell the gripping stories of a dozen species – including the Panamanian golden frog and the Sumatran rhino – some already gone, others at the point of vanishing.

As one of the world’s leading field biologists, George Schaller has spent much of his life traversing wild and isolated places in his quest to understand and conserve threatened species - from mountain gorillas in the Virunga to pandas in the Wolong and snow leopards in the Himalaya. Throughout his celebrated career, Schaller has spent more time in Tibet than in any other part of the world, devoting more than thirty years to the wildlife, culture, and landscapes that captured his heart and continue to compel him.

Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. Life-history research plays an integral role in species conservation and management.

If you live on a rapidly changing planet, you'd be wise to learn how it works. The giant old forests on a skinny stretch of land on the far west coast of North America have a lot to say about living in a twitchy world.

In Wild Sex, Dr. Carin Bondar takes listeners on an enthralling tour of the animal kingdom as she explores the diverse world of sex in the wild. She looks at the evolution of sexual organs (and how they've shaped social hierarchies), tactics of seduction, and the mechanics of sex. She investigates a wide range of topics, from whether animals experience pleasure from sex to what happens when females hold the reproductive power.

The stories we usually tell ourselves about climate change tend to focus on the damage inflicted on human societies by big storms, severe droughts, and rising sea levels. But the most powerful impacts are being and will be felt by the natural world and its myriad species, which are already in the midst of the sixth great extinction. The natural Eden that humanity inherited is quickly slipping away. Although we can never really know what a creature thinks or feels, The End of Eden invites the listener to meet wild species on their own terms in a range of ecosystems that span the globe.

So begins this lively collection of essays by acclaimed filmmaker and novelist Priyanka Kumar. Growing up at the feet of the Himalayas in northern India, Kumar took for granted her immersion in a lush natural world. After moving to North America as a teenager, she found herself increasingly distanced from more than human life and discouraged by the civilization she saw contributing to its destruction. It was only in her twenties, living in Los Angeles and working on films, that she began to rediscover her place in the landscape-and in the cosmos—by way of watching birds.
