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.

In Long Hops, physicist Mark Denny explains, in a clear, conversational style, the science of bird migration - from the intricacies of bird aeronautics to the newly unraveled mysteries of their magnetic compasses. While providing wherever possible examples of indigenous Hawaiian species, the book surveys the migration phenomenon as a whole, showing that birds are breathtaking works of engineering with spectacular capabilities for long-distance flights.

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.

When did the human species turn against the planet that we depend on for survival? Human industry and consumption of resources have altered the climate, polluted the water and soil, destroyed ecosystems, and rendered many species extinct, vastly increasing the likelihood of an ecological catastrophe. How did humankind come to rule nature to such an extent? To regard the planet's resources and creatures as ours for the taking? To find ourselves on a seemingly relentless path toward ecocide?

Biosphere rises from southern Arizona's high desert like a bizarre hybrid spaceship and greenhouse. Packed with more than 3,800 carefully selected plant, animal, and insect species, this mega-terrarium is one of the world's most biodiverse, lush, and artificial wildernesses. Only recently transformed from an abandoned ghost dome to a University of Arizona research center, the site was the setting of a grand drama about humans and ecology at the end of the twentieth century.

Charles Darwin arrived at the Galapagos Islands some three centuries after their discovery. Thousands of seafarers had been there before him, but in these islands Darwin found something more enduring than fresh water and tortoise meat. He found nourishment for an idea - an idea so powerful that its implications revised the place of humans in the universe and enriched every facet of science. Darwin tested and refined his idea for decades before he was persuaded to go public in 1859 by publishing The Origin of Species.

This book presents the fullest account yet written of the impact of Hurricane Katrina on the Mississippi Gulf Coast. Rooted in a wealth of oral histories, it tells the dramatic but underreported story of a people who confronted the unprecedented devastation of sixty five thousand homes when the eye wall and powerful northeast quadrant of the hurricane swept a record thirty-foot storm surge across a seventy-five-mile stretch of unprotected Mississippi towns and cities. James Patterson Smith takes us through life and death accounts of storm day, August 29, 2005, and the precarious days of food and water shortages that followed. Along the way the narrative treats us to inspiring episodes of neighborly compassion and creative responses to the greatest natural disaster in American history

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.

As industry and technology proliferate in modern society, sustainability has jumped to the forefront of contemporary political and environmental discussions. The balance between progress and the Earth's ability to provide for its inhabitants grows increasingly precarious as we attempt to achieve sustainable development.

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.
