One of the most passionate and influential voices for global health equity and social justice, Farmer encourages young people to tackle the greatest challenges of our times. Engaging, often humorous, and always inspiring, these speeches bring to light the brilliance and force of Farmer's vision in a single, accessible volume.

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.

Perhaps more than any other scientist of our century, Edward O. Wilson has scrutinized animals in their natural settings, tweezing out the dynamics of their social organization, their relationship with their environments, and their behavior, not only for what it tells us about the animals themselves, but for what it can tell us about human nature and our own behavior. He has brought the fascinating and sometimes surprising results of these studies to general readers through a remarkable collection of books.

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.

Eye of the Albatross takes us soaring to locales where whales, sea turtles, penguins, and shearwaters flourish in their own quotidian rhythms. Carl Safina’s guide and inspiration is an albatross he calls Amelia, whose life and far-flung flights he describes in fascinating detail. Interwoven with recollections of whalers and famous explorers, Eye of the Albatross probes the unmistakable environmental impact of the encounters between man and marine life.

In this classic work that continues to inspire its many fans, James Lovelock deftly explains his idea that life on Earth functions as a single organism. Written for the non-scientist, Gaia is a journey through time and space in search of evidence with which to support a new and radically different model of our planet. In contrast to conventional belief that living matter is passive in the face of threats to its existence, the book explores the hypothesis that the Earth's living matter - air, ocean, and land surfaces - forms a complex system that has the capacity to keep the Earth a fit place for life.

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.

A century of industrial development is the briefest of moments in the half billion years of the Earth's evolution. And yet our current era has brought greater changes to the Earth than any period in human history. The biosphere, the globe's life-giving envelope of air and climate, has been changed irreparably. In A World to Live In, the distinguished ecologist George Woodwell shows that the biosphere is now a global human protectorate and that its integrity of structure and function are tied closely to the human future.

In a bid to create the perfect sustainable food production system, aquaponics was born. This system has been adopted worldwide and used extensively. However, many people tend to take up this food production technique without having basic knowledge of what it entails. As a result, their systems flop and fail to perform to their expectations. This has prompted educational campaigns geared toward familiarizing the community with the practice.

This light-hearted collection of memoirs tells the compelling story of a company executive who walked away from global corporations and immersed himself in the world of non-profit; in this case, WWF, one of the world's largest conservation organizations. After years of working in the corporate sector, C.Y. Chong decided to pursue a new avenue of work. He joined WWF International as a finance manager and was soon promoted to director of finance; however, this book is about his non-financial experiences.

In this fascinating book, Terry O'Connor explores a distinction that is deeply ingrained in much of the language that we use in zoology, human-animal studies, and archaeology - the difference between wild and domestic. For thousands of years, humans have categorized animals in simple terms, often according to the degree of control that we have over them, and have tended to see the long story of human-animal relations as one of increasing control and management for human benefit.

A lively blend of memoir, natural history, and mindfulness, Zooburbia is an inspirational collection of stories of the wildlife with whom we coexist. In Zooburbia, urban naturalist Tai Moses explores the "extraordinary, unruly, half-wild realm where human and animal lives overlap."

On their journey westward, Lewis and Clark demonstrated an amazing ability to identify the new plants and animals they encountered, and their observations enriched science's understanding of the trans-Mississippi West. Others have written about their discoveries and have faithfully cataloged their findings; now a 21st-century biologist reexamines some of those discoveries in the light of modern science to show for the first time their lasting biological significance.

Bill Belleville's enchanting Salvaging the Real Florida invites listeners to rediscover treasures hidden in plain sight. Join Belleville as he paddles a glowing lagoon, slogs through a swamp, explores a spring cave, dives a "literary" shipwreck, and pays a visit to the colorful historic district of an old riverboat town. Journey with him in search of the apple snail, the black bear, a rare cave-dwelling shrimp, and more. Everywhere he goes, Belleville finds beauty, intrigue, and, more often than not, a legacy in peril.

Naturalist Joe Hutto’s latest adventures in wildlife observation take him to Wyoming’s Wind River Mountains. Hutto is living in a tent at 12,000 feet, where blizzards occur in July and where human wants become irrelevant—and human needs can become a matter of life and death—to study the Rocky Mountain bighorn sheep.

Emmy Award - winning filmmaker, writer, and naturalist Joe Hutto has done it again. Touching the Wild is the enchanting story about one man who has lived with a herd of mule deer in the Wind River mountains of Wyoming for almost seven years. Why, you may ask, would a person choose to do such a thing? His response: how could you not? For Joe Hutto, close proximity to wild things is irresistible. In Illumination in the Flatwoods he unveiled the secret lives of the wild turkey to great critical acclaim.

We live in a world awash in manmade chemicals, from the pesticides on our front lawns to the diesel exhaust in the air we breathe. Although experts are beginning to understand the potential dangers of these substances, there are still more than 80,000 synthetic compounds that have not been sufficiently tested to interpret their effects on human health.

El reino vegetal: un mundo enorme que abarca desde seres vivos microscópicos hasta los grandes árboles de cien metros de altura y más de cien toneladas. La clorofila: responsable de la fotosíntesis. Las primeras plantas aparecieron en el mar y eran algas unicelulares. Evolución. El paso de la tierra: los musgos y helechos, las coníferas, plantas con flores... Características y dispositivos especiales de cada uno. Al incinerar los cuerpos de diferentes seres vivos, comprobamos que sus cenizas se parecen mucho entre sí. El 95% de su composición está formada por: carbono, hidrógeno, oxígeno y nitrógeno. La vida es ahorrativa, prefiere utilizar sólo unos pocos elementos, que son, por otra parte, los más comunes del Universo. Además, tales elementos se reciclan constantemente: las plantas absorben el nitrógeno, los herbívoros incorporan dichas substancias a sus organismos, para posteriormente pasar a los carnívoros. El nitrógeno vuelve a la tierra en forma de excrementos. El C02 es absorbido por las plantas gracias a la fotosíntesis. Luego vuelve a la atmósfera a través de la respiración de animales y plantas y a través de microorganismos que al descomponer la materia orgánica devuelven el carbono al medio ambiente.

Our day-to-day experiences over the past decade have taught us that there must be limits to our tremendous appetite for energy, natural resources, and consumer goods. Even utility and oil companies now promote conservation in the face of demands for dwindling energy reserves. And for years some biologists have warned us of the direct correlation between scarcity and population growth.
