Why a saltwater aquarium? There's nothing more spectacular than the diversity of the ocean. A saltwater aquarium setup allows you to bring a little sample of that spectacle into your own living room. Compared to plain freshwater tanks (which commonly contain goldfish and other lake-bred varieties of fish), there are many more options if you're planning to choose a saltwater aquarium setup. The fish and other ocean creatures you'll be able to host range from beautiful to fascinating to downright weird, some displaying flashy colors while others exude a quiet grace.    

The biggest redwood trees are over 1,000 years old, rising more than 35 stories in what's left of the once-vast, ancient redwood forest. Believed to be impossible to ascend, these majestic giants have remained unexplored until recently, when a tiny group of daring botanists and amateur naturalists discovered a lost, dangerous, and hauntingly beautiful world high above California.

From the Yangtze to the Yellow River, China is traversed by great waterways, which have defined its politics and ways of life for centuries. Water has been so integral to China's culture, economy, and growth and development that it provides a window on the whole sweep of Chinese history. In The Water Kingdom, renowned writer Philip Ball opens that window to offer an epic and powerful new way of thinking about Chinese civilization. Water, Ball shows, is a key that unlocks much of Chinese culture.

Volcanoes have fascinated - and terrified - people for ages. They have destroyed cities and ended civilizations. In this book, John Dvorak, the acclaimed author of Earthquake Storms, looks into the early years of volcanology and its "father", Thomas Jaggar. Jaggar was the youngest of five scientists to investigate the explosion of Mount Pelee in Martinique, which leveled the entire city of St. Pierre and killed its entire population in two minutes.

Marco Polo (1254-1324), is probably the most famous Westerner who traveled on the "Silk Road." His journey through Asia lasted 24 years. He traveled the whole of China and returned to tell the tale, which became one of the world's greatest travelogues.

The earth has died many times, and it always comes back looking different. In an exhilarating, surprising exploration of our planet, Craig Childs takes listeners on a firsthand journey through apocalypse, touching the truth behind the speculation. Apocalyptic Planet is a combination of science and adventure that reveals the ways in which our world is constantly moving toward its end and how we can change our place within the cycles and episodes that rule it.

In 1793 William Smith, a canal digger, made a startling discovery that was to turn the fledgling science of the history of the earth - and a central plank of established Christian religion - on its head. He noticed that the rocks he was excavating were arranged in layers; more important, he could see quite clearly that the fossils found in one layer were very different from those found in another. And out of that realization came an epiphany.

Renowned scientist and best-selling author Jane Goodall delivers an eye-opening and empowering book that explores the social and personal significance of what we eat. In Harvest for Hope, Jane Goodall presents an empowering and far-reaching vision for social and environmental transformation through the way we produce and consume the foods we eat.

Published to coincide with the centenary of the first expeditions to reach the South Pole, An Empire of Ice presents a fascinating new take on Antarctic exploration. Retold with added information, it's the first book to place the famed voyages of Norwegian explorer Roald Amundsen, his British rivals Robert Scott and Ernest Shackleton, and others in a larger scientific, social, and geopolitical context.

Taking listeners from the melting Alaskan permafrost to storm-torn New Orleans, acclaimed journalist Elizabeth Kolbert approaches this monumental problem from every angle. She interviews researchers and environmentalists, explains the science, draws frightening parallels to lost civilizations, and presents the moving tales of people who are watching their worlds disappear.

The award-winning climate scientist Michael E. Mann and the Pulitzer Prize-winning political cartoonist Tom Toles have been on the front lines of the fight against climate denialism for most of their careers. They have witnessed the manipulation of the media by business and political interests and the unconscionable play to partisanship on issues that affect the well-being of billions. The lessons they have learned have been invaluable, inspiring this brilliant escape hatch from the madhouse of the climate wars.

In this fresh and powerful work of environmental history, Martin Doyle explores how rivers have often been the source of arguments at the heart of the American experiment - over federalism, taxation, regulation, conservation, and development. Doyle tells the epic story of America and its rivers, from the US Constitution's roots in interstate river navigation, the origins of the Army Corps of Engineers, the discovery of gold in 1848, and the construction of the Hoover Dam and the TVA during the New Deal, to the failure of the levees in Hurricane Katrina.

For months in early 1980, scientists, journalists, and ordinary people listened anxiously to rumblings in the long quiescent volcano Mount St. Helens. Still, when a massive explosion took the top off the mountain, no one was prepared. Fifty-seven people died, including newlywed logger John Killian (for years afterward, his father searched for him in the ash), scientist Dave Johnston, and celebrated local curmudgeon Harry Truman. The lives of many others were forever changed.

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.

If you find yourself worried about all of the junk that is tainting the American food supply, then you might want to consider starting your own garden. Yet, if you use tap water and fertilizers you buy from the store to tend to that garden, you just might be tainting the produce you are growing. One of the best ways to have a garden and avoid these problems is to garden off the grid.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

In Waves, Fredric Raichlen traces the evolution of waves, from their generation in the deep ocean to their effects on the coast. He explains, in a way that is readily understandable to nonscientists, both the science of waves themselves and the technology that can be used to protect us against their more extreme forms, including hurricanes and tsunamis.

The idea of a missing link between humanity and our animal ancestors predates evolution and popular science and actually has religious roots in the deist concept of the Great Chain of Being. Yet, the metaphor has lodged itself in the contemporary imagination, and new fossil discoveries are often hailed in headlines as revealing the elusive transitional step, the moment when we stopped being "animal" and started being "human". In The Accidental Species, Henry Gee, longtime paleontology editor at Nature, takes aim at this misleading notion.

Why did the line of ancient humans who eventually evolved into us survive when the others were shown the evolutionary door? Chip Walter draws on new scientific discoveries to tell the fascinating tale of how our survival was linked to our ancestors being born more prematurely than others, having uniquely long and rich childhoods, evolving a new kind of mind that made us resourceful and emotionally complex; how our highly social nature increased our odds of survival; and why we became self aware in ways that no other animal seems to be.

Beyond what we already know about "food miles" and eating locally, the global food system is a major contributor to climate change, producing as much as one-third of greenhouse gas emissions. How we farm, what we eat, and how our food gets to the table all have an impact. And our government and the food industry are willfully ignoring the issue rather than addressing it. In Anna Lapp's controversial new book, she predicts that unless we radically shift the trends of what food we're eating and how we're producing it, food-system-related greenhouse gas emissions will go up and up and up.
