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.

As a botanist and professor of plant ecology, Robin Wall Kimmerer has spent a career learning how to ask questions of nature using the tools of science. As a Potawatomi woman, she learned from elders, family, and history that the Potawatomi, as well as a majority of other cultures indigenous to this land, consider plants and animals to be our oldest teachers.

A riveting exploration of how microbes are transforming the way we see nature and ourselves - and could revolutionize agriculture and medicine. Prepare to set aside what you think you know about yourself and microbes. Good health - for people and for plants - depends on Earth's smallest creatures. The Hidden Half of Nature tells the story of our tangled relationship with microbes and their potential to revolutionize agriculture and medicine, from garden to gut.

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.

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.

Flowers, and the fruits that follow, feed, clothe, sustain, and inspire all humanity. Flowers are used to celebrate all-important occasions, to express love, and are also the basis of global industries. Americans buy 10 million flowers a day, and perfumes are a worldwide industry worth $30 billion annually. Stephen Buchmann takes us along on an exploratory journey of the roles flowers play in the production of our foods, spices, medicines, and perfumes while simultaneously bringing joy and health.

Published in 1951, The Sea Around Us is one of the most remarkably successful books ever written about the natural world. This classic work remains as fresh today as when it first appeared. Carson's writing teems with stunning, memorable images - the newly formed Earth cooling beneath an endlessly overcast sky, the centuries of nonstop rain that created the oceans, giant squids battling sperm whales hundreds of fathoms below the surface, and incredibly powerful tides moving 100 billion tons of water daily in the Bay of Fundy.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built - and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.

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.

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."

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.

Caradonna's unique and concise history broadens our understanding of what "sustainability" means, revealing how it progressed from a relatively marginal concept to an ideal that shapes everything from individual lifestyles, government and corporate strategies, and even national and international policy. For anyone seeking understand the history of those striving to make the world a better place to live, here's a place to start.

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.

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.

One bright day in December 2001, sixty-two-year-old Germaine Greer found herself confronted by an irresistible challenge in the shape of sixty hectares of dairy farm, one of many in southeast Queensland, Australia, which, after a century of logging, clearing, and downright devastation, had been abandoned to their fate. She didn’t think for a minute that by restoring the land she was saving the world. She was in search of heart’s ease.

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.
