Why a unicycle? Why a cross-country trip? Why leave a prominent New York magazine and return to the simple life in Kentucky? Reminiscent of classic literary travelogues, Mark Schimmoeller's Slowspoke: A Unicyclist's Guide to America takes listeners on an inward, emotional journey as he inches across landscapes and communities from North Carolina to Arizona. Schimmoeller became inspired by his unicycle as an adolescent.

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.

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.

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.

The sixth "mass extinction event" in the history of planet Earth is currently under way, with over two hundred species dying off every day. The cause of this seismic event is also the source of the single biggest threat to human life: our own inventions. But for all our talk about sea levels and biotechnology, do we really know what our future will actually look like? Will our immune systems be attacked by so-called super bugs, always evolving, and more easily spread than ever? Will the disappearance of numerous species cripple the biosphere?

Told with Thoreauian poeticism and appreciation to detail, Morgan Bulkeley Sr. guides the listener through the wonders of one of the World's most beautiful natural landscapes: that of the Berkshires of Massachusetts.

"Qualsiasi tentativo di trovare una via d'uscita non è altro che un ulteriore paradosso, dato che viene utilizzato lo strumento della coscienza con il fine di contrastare gli errori della coscienza stessa. Il che è un assurdo." Un'inquietante quanto affascinante nuova visione del destino di Homo sapiens nel XXI secolo. È possibile che l'umanità si sia cacciata in un vero e proprio vicolo cieco evolutivo? Vale a dire che il riscaldamento progressivo del pianeta determinato dall'hybris di Homo, con la crisi climatica che lo accompagna, abbia come esito l'estinzione.

Den globala ekonomin har länge byggt på obegränsade resurser och ständig tillväxt. Nu vet vi att vårt sätt att leva är ohållbart och allt fler ser över sina konsumtionsvanor. Vi pantar burkar, sopsorterar och köper ekologiskt. Men faktum är att ett hållbart sparande kan göra mer för klimatet och för ett hållbart samhälle. Dessutom är det lönsamt då bolag som satsar på hållbarhet nu går om sina konkurrenter och får bättre avkastning.

Der Umweltjournalist Andreas Schlumberger versammelt 50 einfache Dinge, die Sie tun können, um die Welt zu retten und zeigt, dass es viele - oft überraschend einfache - Möglichkeiten gibt, den eigenen Alltag umweltverträglicher zu gestalten. Nahezu unbekannt ist: Bei unzähligen Tipps lässt sich sogar Geld sparen! Ob Ernährung, Haushalt oder Mobilität - überall verstecken sich Ausgabequellen, die der Umwelt schaden und das Portemonnaie belasten. Sie lassen sich clever umgehen, ohne Komfortverzicht und ohne am bisherigen Lebensstil zu rütteln.

En 2013, las amigas Liesl Clark y Rebecca Rockefeller se dieron cuenta de la cantidad de residuos que había en sus playas locales - desde plumas y popotes hasta juguetes y cepillos de dientes - y decidieron hacer algo al respecto. Así nació el proyecto Buy Nothing.

Seitdem Menschen sesshafte Landwirtschaft betreiben, kommt es immer wieder zu tödlichen Epidemien. Aber warum nehmen diese Infektionen heute die Form weltweiter Pandemien an, so wie es bei COVID-19, SARS, MERS oder der Vogelgrippe der Fall war? Warum häufen sie sich - und was lässt sich dagegen unternehmen? Der US-amerikanische Biologe Rob Wallace erklärt, wie Pandemien entstehen und warum sie sich global ausbreiten. In seiner Analyse berücksichtigt er die evolutionäre Dynamik der Krankheitserreger ebenso wie die gegenwärtigen ökologischen und ökonomischen Strukturen.

Die gesammelten Reden der 16-jährigen Klimaschutz-Aktivistin Greta Thunberg dokumentieren ihren Aufruf zum weltweiten Schulstreik für das Klima. Unter #FridaysForFuture demonstrieren Tausende Schüler jeden Freitag mit ihr gemeinsam gegen CO2-Emissionen, die Verbrennung fossiler Energieträger und den menschengemachten Klimawandel. In ihren mittlerweile weltweit bekannten Reden, vor dem schwedischen Parlament, bei der Weltklimakonferenz in Kattowitz oder beim Weltwirtschaftsforum in Davos, fordert Greta Thunberg eine radikale Kehrtwende in der Klimapolitik und die Einhaltung des Pariser Klimaabkommens.

Come limitare l'impatto dei consumi di energia sull'uomo e sull'ambiente, senza compromettere lo sviluppo economico? Un impiego delle fonti rinnovabili, e in particolare dell'energia solare, è ormai ritenuto necessario e possibile, anche in ampie proporzioni. Nel volume si discutono gli aspetti tecnologici ed economici dello sfruttamento dell'energia solare e si offre un quadro delle politiche nazionali e dell'Unione europea nel settore.

Barcellona, Manchester o Salonicco, Torino, Bari o Genova: cosa hanno in comune queste città? Il fatto che possono essere considerate smart, misurandole con diversi parametri che vanno dai trasporti all'istruzione, dalla sanità alla sostenibilità ambientale all'innovazione tecnologica. Smart city è dunque una definizione complessa cha allude ad una trasformazione delle nostre attuali città con l'obiettivo non solo del superamento delle emergenze energetiche ed ambientali, ma anche della qualità del vivere per il cittadino e per la comunità, sul piano sociale ed economico.
