Animal migration is a magnificent sight: a mile-long blanket of cranes rising from a Nebraska river and filling the sky; hundreds of thousands of wildebeests marching across the Serengeti; a blaze of orange as millions of monarch butterflies spread their wings to take flight. Nature’s great migrations have captivated countless spectators, none more so than premier ecologist David S. Wilcove. In No Way Home, his awe is palpable - as are the growing threats to migratory animals.

Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built - and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.

The Digital Age was expected to usher in an era of clean production, an alternative to smokestack industries and their pollutants. But as environmental journalist Elizabeth Grossman reveals in this penetrating analysis of high tech manufacture and disposal, digital may be sleek, but it's anything but clean. Deep within every electronic device lie toxic materials that make up the bits and bytes, a complex thicket of lead, mercury, cadmium, plastics, and a host of other often harmful ingredients.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.

In Getting to Green, Frederic C. Rich argues that meaningful progress on urgent environmental issues can be made only on a bipartisan basis. Rich reminds us of American conservation's conservative roots and of the bipartisan political consensus that had Republican congressmen voting for, and Richard Nixon signing, the most important environmental legislation of the 1970s.

Beginning in his kayak in his home waters of eastern Long Island, Carl Safina's The View from Lazy Point takes us through the four seasons to the four points of the compass, from the high Arctic south to Antarctica, across the warm belly of the tropics from the Caribbean to the west Pacific, then home again.

Climate change is a major topic of concern today and will be so for the foreseeable future, as predicted changes in global temperatures, rainfall, and sea level continue to take place. But as Jan Zalasiewicz and Mark Williams reveal in The Goldilocks Planet, the climatic changes we are experiencing today hardly compare to the changes the Earth has seen over the last 4.5 billion years.

Our basic right to healthy food is at risk. What can we do? Written in an astute, engaging style, armed with examples from her own homesteading lifestyle, small farmer Nicole Faires' Food Confidential gives you the tools to fight the intangible battles as well as the practical ones.

Ticked: The Battle Over Lyme Disease in the South is the second installment of Discover In-Depth, Discover magazine's new longform series. In this deep investigation of the science surrounding Lyme disease, writer Wendy Orent dissects how tick-borne illness is diagnosed in the Southern United States, where the Centers for Disease Control and Prevention (CDC) do not recognize Lyme even though thousands of people in the South have reported Lyme-like symptoms and debilitating illness.

Beyond images of emaciated polar bears and drought-cracked lakes, there remains a major part of climate change's impact that the media has neglected: how our health will suffer from higher temperatures and extreme weather. From spiraling rates of asthma and allergies and spikes in heatstroke-related deaths to swarms of invasive insects carrying diseases like dengue or West Nile and increases in heart and lung disease and cancer, the effect of rising temperatures on human health will be far-reaching, and is more imminent than we think.

In its 2001 report on global climate, the Intergovernmental Panel on Climate Change of the United Nations prominently featured the "Hockey Stick", a chart showing global temperature data over the past 1,000 years. The Hockey Stick demonstrated that temperature had risen with the increase in industrialization and use of fossil fuels. The inescapable conclusion was that worldwide human activity since the industrial age had raised CO2 levels, trapping greenhouse gases in the atmosphere and warming the planet.

Mark Seth Lender’s home is on the edge of a salt marsh. From his front porch and back yard he is witness to an astonishing array of wildlife, but nothing he sees is more beautiful and inspiring than the birds that fill the air, perch on trees and wade in shallow water. His reports on the sighting of birds like great horned owls, little blue herons and snowy egrets are featured in the segment "Salt Marsh Diary" heard on NPR’s Living on Earth. For the first time, he has chronicled the marsh’s life in a book penned from his perch.

The monumental statues of Easter Island, both so magisterial and so forlorn, gazing out in their imposing rows over the island’s barren landscape, have been the source of great mystery ever since the island was first discovered by Europeans on Easter Sunday 1722. How could the ancient people who inhabited this tiny speck of land, the most remote in the vast expanse of the Pacific islands, have built such monumental works?

After the death of his brother and the sudden end of his marriage, and after his ex-wife moved to another state leaving him alone with their two young children, Dan Glick embarked on single fatherhood in an unusual way: he took his kids on a journey around the world. The idea was to go see some of the world's rare life forms before they disappeared from the planet, and to do it before the kids themselves would grow up and chart their own paths.

Bottled water is on the verge of becoming the most popular beverage in the country. But what's the cost of all this water for us and for the environment? In this eye-opening book, Elizabeth Royte does for water what Michael Pollan did for food: She examines the people, machines, economies, and cultural trends that surround it on its journey from distant aquifers to our supermarkets and homes.

This book shows that the quantitative mathematical models policy makers and government administrators use to form environmental policies are seriously flawed. Based on unrealistic and sometimes false assumptions, these models often yield answers that support unwise policies. Writing for the general, nonmathematician reader, the authors begin with a riveting account of the extinction of the North Atlantic cod on the Grand Banks of Canada.

Climate change is with us, and we need to think about the next big disturbing idea - the potentially disastrous consequences of massive numbers of environmental refugees at large on the planet. In 2020, the United Nations projects that we will have 50 million environmental refugees mostly from Africa, Asia, and Latin America. How will people be relocated and settled? Is it possible to offer environmental refugees temporary or permanent asylum? Will these refugees have any collective rights in the new areas they inhabit?

For over a quarter century, biologist Mark J. Rauzon has worked in the field of island restoration, traveling throughout the American Insular Pacific to eradicate invasive plants and animals introduced by humans. The region spans from Hawai'i to Samoa to Guam, and their neighbors - small, obscure, tropical islands that are hundreds if not thousands of nautical miles from each other. These little-known US possessions and territories include various islands and atolls: Jarvis, Howland, Baker, the Northern Marianas, Wake, Palmyra, Johnston, and Rose Atoll, among others.

Gene Logsdon's The Man Who Created Paradise is a message of hope at a time when the very concept of earth stewardship is under attack. The fable, inspired by a true story, tells how Wally Spero looked at one of the bleakest places in America -- a raw and barren strip-mined landscape -- and saw in it his escape from the drudgery of his factory job. He bought an old bulldozer and used the machine to carve patiently, acre by acre, a beautiful little farm out of a seemingly worthless wasteland.
