This Is Planet Earth is dedicated to the wonders of planet Earth, the most amazing place in the known universe. The ancient Greeks called it Gaia, the Romans Terra. We know it simply as Earth, the planet we call home. And what a planet it is. Formed around 4.6 billion years ago from the debris of the big bang and long-dead stars, at first it was nothing special, but somehow it evolved to become the most amazing place in the known universe.

This audiobook includes an introduction to basics of where to find gold, what materials you need, and a bunch of other tips that will increase your odds of finding gold.

The notion of a living world is one of humanity’s oldest beliefs. Though once scorned by many scientists, the concept of Earth as a vast interconnected living system has gained acceptance in recent decades. Life not only adapts to its surroundings – it also shapes them in dramatic and enduring ways. Over billions of years, life transformed a lump of orbiting rock into our cosmic oasis, breathing oxygen into the atmosphere, concocting the modern oceans, and turning rock into fertile soil. Life is intertwined with Earth’s capacity to regulate its climate and maintain balance.

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.

More than half a billion years ago, our world was completely covered by glaciers, a "Snowball Earth" that persisted for millions of years. Incredibly, this unimaginable cold led to the remarkable diversification of life on earth known as the Cambrian explosion. With a geologist's eye and a knack for storytelling, Graham Shields explores when and how such inhospitable conditions enabled animals to evolve, radiate, and diversify into our earliest ancestors.

What is deep within the core?

End Times is a compelling work of skilled reportage that peels back the layers of complexity around the unthinkable - and inevitable - end of humankind. From asteroids and artificial intelligence to volcanic supereruption to nuclear war, veteran science reporter and TIME editor Bryan Walsh provides a stunning panoramic view of the most catastrophic threats to the human race.

Matthew Hart embarks on a journey into the largely hidden and fascinating world that is the diamond trade. The geology of diamonds explains how hard it is to find them. They are accidents of nature, carbon crystals compressed underground for eons. Weaving science and history, Hart follows the diamond trail from the basement where Gabi Tolkowsky, the world's greatest cutter, faced the 599-carat Centenary diamond, to Africa's Diamond Coast, to the sales rooms of De Beers.

Darius Cobb wasn't thinking of man's extinction. He honestly never gave it a thought. A college professor and part time country singer, Darius worried only about teaching and playing his guitar until the day he is attacked by cockroaches and is placed into a special government quarantine. There, he and the others start piecing together the inevitable. Using his knowledge, he begins predicting the events that unfold. Together he and his group plan and then implement a long term survival plan.

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.

Glaciers: The Politics of Ice is a scientific, cultural, and political examination of the cryosphere - the earth's ice - and the environmental policies that aim to protect it. Jorge Daniel Taillant discusses the debates and negotiations behind the passing of the world's first glacier protection law in the mid-2000s and reveals the tension between the industry experts, politicians, and glacier conservationists.

When Will Hunt was 16 years old, he discovered an abandoned tunnel that ran beneath his house in Providence, Rhode Island. His first tunnel trips inspired a lifelong fascination with exploring underground worlds, from the derelict subway stations and sewers of New York City to sacred caves, catacombs, tombs, bunkers and ancient underground cities in more than 20 countries around the world.

Sky at Night presenter Dr Tim Gregory takes us on a journey through the very earliest days of our Solar System to the spectacular meteorite falls that produced 'fiery rain' in 1792, to the pre-solar grains (literally stardust) that were blown in from other solar systems and are the oldest solid objects ever discovered on earth. Meteorites reveal a story much bigger than ourselves or our planet. As Tim says, 'It is an epic beyond compare.'

In the middle of New York City lies a neighborhood where all secrets are valuable, all assets are liquid, and all deals are sealed with a blessing rather than a contract. Welcome to the diamond district. Ninety percent of all diamonds that enter America pass through these few blocks, but the inner workings of this mysterious world are known only to the people who inhabit it.

Meteorites, methane, mega-volcanoes and now human beings; the old forces of nature that transformed Earth many millions of years ago are joined by another: us. Our actions have driven Earth into a new geological epoch, the Anthropocene. For the first time in our home planet's 4.5-billion year history a single species is dictating Earth's future. To some the Anthropocene symbolises a future of superlative control of our environment. To others it is the height of hubris, the illusion of our mastery over nature.

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.

If you listen, can you hear the stones speak? The question seems absurd. After all, rocks are lifeless, inert, and silent. In The Whispers of Rock earth scientist Anjana Khatwa asks us to think again, and listen to their stories. Boldly alternating between modern science and ancient wisdom, Khatwa takes us on an exhilarating journey through deep time, from origins of the green pounamu that courses down New Zealand rivers to the wonder of the bluestone megaliths of Stonehenge, from the tuff-hewn churches of Lalibela, Ethiopia, to Manhattan’s bedrock of schist.

Путешествие по земному шару и открытие новых стран, морей, народов в высшей степени способствовали духовному развитию человечества.
