The Earth is alive, and we are utterly and totally dependent upon its remaining vitality and self-regulation if we have any hope of surviving as a species. Current approaches to doing the right or useful ecological actions are necessary but not sufficient. We need more than window dressing and superficial action. We have to get deeper into causes of how we got to where we are. The audiobook focuses on that deeper understanding and the transformation needed to really address the ills that affect Gaia.

How can you truly belong to a place? What does being at home mean in a society that has always celebrated the search for greener pastures? And can a newcomer ever acquire the deep understanding of the land that comes from being part of a culture that has lived there for centuries? When Daniel Coleman came to Hamilton to take a position at McMaster University, he began to ask himself these kinds of questions, and Yardwork: A Biography of an Urban Place is his answer.

There are more than 180 exotic species in the Great Lakes. Some, such as the Asian tapeworm, have had little or no impact so far. But a handful of others - sea lamprey, alewife, spiny water flea, rusty crayfish, and more - have conducted an all-out assault on the Great Lakes and are winning the battle. Here, William Rapai focuses on the impact of these invasives. Rapai begins with a brief biological and geological history of the Great Lakes. He examines new policies and the tradeoffs that must be weighed, and ends with an inspired call for action.

In questo audiolibro esclusivo Simone Bedetti ti introduce al pensiero di un grande scienziato e filosofo della natura, il premio Nobel per la chimica Ilya Prigogine. Prigogine, tra gli iniziatori della scienza della complessità, noto per le sue teorie sulle strutture dissipative, i sistemi complessi e l'irreversibilità, ha proposto una nuova e radicale visione del mondo riformulando il secondo principio della termodinamica: ogni processo naturale è irreversibile e tende ad aumentare la sua entropia (e quella dell'ambiente in cui si trova).

In 1839, two years after graduating from Harvard, Henry David Thoreau and his older brother, John, took a boat-and-hiking trip from Concord, Massachusetts, to the White Mountains of New Hampshire. After John's sudden death in 1842, Thoreau began to prepare a memorial account of their excursion during his stay at Walden Pond. Modern listeners have come to see Thoreau's story of the river journey as an appropriate predecessor to Walden, depicting the early years of his spiritual and artistic growth.

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.

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 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.

Capire l'oggi per creare il domani. Un percorso di trasformazione su tre livelli: spirituale, culturale e tecnico. L'Uomo si è ormai perso nella sua rincorsa feroce al progresso, tutti gli ambiti delle sue attività danno continui messaggi d'allarme. L'ecosistema terrestre e la vita dell'Uomo stesso non sono mai stati messi a rischio come in questi ultimi decenni di enorme sviluppo industriale ed economico.

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.

Notre planète va mal : réchauffement climatique, épuisement des ressources naturelles, pollutions des sols et de l'eau provoquées par les industries civiles et guerrières, disparité des richesses, malnutrition des hommes, taux d'extinction effarant des espèces vivantes, etc. La situation est-elle vraiment dramatique ? Que penser des thèses qui contestent ce pessimisme ?

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."

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.

By turns epic and intimate, Telling Our Way to the Sea is both a staggering revelation of unraveling ecosystems and a profound meditation on our changing relationships with nature - and with one another. When the biologists Aaron Hirsh and Veronica Volny, along with their friend Graham Burnett, a historian of science, lead twelve college students to a remote fishing village on the Sea of Cortez, they come upon a bay of dazzling beauty and richness.

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.

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.

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 the 2012 edition of its flagship report, Worldwatch celebrates the twentieth anniversary of the 1992 Earth Summit with a far-reaching analysis of progress toward building sustainable economies. Written and read in clear language, State of the World 2012 offers a new perspective on what changes and policies will be necessary to make sustainability a permanent feature of the world's economies.

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.
