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.

In the dramatic narratives that comprise The Republic of Nature, Mark Fiege reframes the canonical account of American history based on the simple but radical premise that nothing in the nation's past can be considered apart from the natural circumstances in which it occurred. Revisiting historical icons so familiar that schoolchildren learn to take them for granted, he makes surprising connections that enable readers to see old stories in a new light.

Down to the Wire is a sober and eloquent assessment of climate destabilization and an urgent call to action. David Orr describes how political negligence, an economy based on the insatiable consumption of trivial goods, and a disdain for the well-being of future generations have brought us to the tipping point that biologist Edward O. Wilson calls "[T]he bottleneck".

Long before the phrase 'climate change' was a universal catchphrase, His Royal Highness the Prince of Wales was studying the impact of industrialization on the environment. Now in this fascinating cross-discipline work, the Prince of Wales calls upon his years of research and explores the way in which mankind must work to restore the delicate balance with nature that we've lost in the centuries since the industrial revolution began.

In 1926, Henry Beston spent two weeks in a two-room cottage on the sand dunes of Cape Cod. He had not intended to stay longer, but, as he later wrote, "I lingered on, and as the year lengthened into autumn, the beauty and mystery of this earth and outer sea so possessed and held me that I could not go."

In Seven Dirty Words, journalist and cultural critic James Sullivan tells the story of Alternative America from the 1950s to the present, from the singular vantage point of George Carlin, the Catholic boy for whom nothing was sacred.

The Great Lakes - Erie, Huron, Michigan, Ontario, and Superior - hold 20 percent of the world's supply of surface fresh water and provide sustenance, work, and recreation for tens of millions of Americans. But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan's engaging portrait of an ecological catastrophe happening right before our eyes.

Dès sa première édition, en 2012, cet œuvre a été la première à décrire la dimension mondiale des alternatives économiques, démocratiques et écologiques mises en place par la société civile. Elle a séduit toute une génération qui se reconnaît dans cette invention d'un nouveau monde et a reçu le Prix 2013 du Livre de l'Environnement. Avec cette 2ème édition, enrichie de nouvelles alternatives, l'auteure poursuit son voyage.

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.

Speaking from the cultural viewpoint of the Lakota of the northern Plains, the author discusses the evolution of native cultures to fit within the environment and adapt to it, as opposed to changing it drastically or wholesale to fit human needs and comforts. He suggests that changing our contemporary thinking in relating to the earth in a less harmful way does not mean a drastic change in lifestyles....

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.

Almir Narayamoga Surui, the Amazonian tribal chieftain of the indigenous Surui people, is a leader in the fight to save the rainforest not only for the preservation of his land and people, but for the Earth's and humanity's survival as well. Joining forces with such high-tech corporations as Apple and Google Earth, Surui has become a guardian of his people and a global activist, despite death threats and million-dollar bounties on his head.

The problem of agriculture is as old as civilization. Throughout history, great societies that abused their land withered into poverty or disappeared entirely. Now we risk repeating this ancient story on a global scale due to ongoing soil degradation, a changing climate, and a rising population. But there is reason for hope. David R. Montgomery introduces us to farmers around the world at the heart of a brewing soil health revolution that could bring humanity's ailing soil back to life remarkably fast.
