En los bosques suceden cosas sorprendentes: árboles que se comunican entre sí, árboles que aman y cuidan a sus hijos y a sus viejos y enfermos vecinos; árboles sensibles, con emociones, con recuerdos... ¡Increible, pero cierto!Peter Wohlleben, guarda forestal y amante de la naturaleza, nos narra en este libro fascinantes historias sobre las insospechadas y extraordinarias habilidades de los arboles. Asimismo reune por una parte los ultimos descubrimientos cientificos sobre el tema, y por otra sus propias experiencias vividas en los bosques; y con todo ello nos ofrece un emocionante punto de vista, una manera de conocer mejor a unos seres vivos con los que creemos estar familiarizados pero de los que desconocemos su capacidad de comunicacion, su espiritualidad. Descubramos, gracias a este libro, un mundo totalmente nuevo

En pocas décadas, la humanidad ha experimentado una revolución en sus hábitos ancestrales. Sin que nos demos cuenta, nuestra especie ha pasado de habitar cada rincón de la Tierra, inmersa en la naturaleza, a vivir en una parte verdaderamente infima de las tierras emergidas del planeta: la ciudad. Una revolucion solo comparable a la transicion de cazadores-recolectores a agricultores que se produjo hace 12.000 años. Es cierto que en terminos de acceso a los recursos, eficiencia, defensa y difusion de las especies esta transformacion es ventajosa. Pero tambien nos expone a un riesgo terrible. Nuestro exito urbano requiere, de hecho, un flujo continuo y exponencialmente creciente de recursos y energia, que sin embargo no son ilimitados. Ademas, el calentamiento global puede cambiar definitivamente el entorno de nuestras ciudades y constituir precisamente esa mutacion fatal de las condiciones de las que depende nuestra supervivencia. Por eso se ha vuelto vital devolver la naturaleza a nuestro habitat. Las ciudades del futuro, ya sean construidas desde cero o renovadas, deben transformarse en fitopolis, lugares donde la relacion entre plantas y animales se acerque a la relacion armoniosa que encontramos en la naturaleza. No hay nada de mayor importancia que esto para el futuro de la humanidad.

"Con una combinación de datos fascinantes sobre un centenar de árboles e increíbles historias de su importancia para las civilizaciones antiguas, el comercio, las creencias religiosas y paganas, el bienestar y los usos medicinales a lo largo de los siglos, este delicioso y bien documentado libro suscita la curiosidad en cada una de sus paginas". Doctora Alexandra Wagstaffe. Eden Project Learning * "Historias maravillosas e informacion detallada que no suelen encontrarse en los libros sobre arboles". Piet Oudolf. Paisajista y responsable del diseño de plantacion del parque High Line, Nueva York Una obra en la que los autores logran transmitir la importancia de los arboles al tiempo que vinculan sus rasgos a nuestra historia humana a traves de los tiempos. Como si de una reunion de viejos amigos se tratara, esta historia de los arboles, muy bien documentada, nos recuerda a aquellos con los que estamos familiarizados, y, a la vez, nos intriga con detalles e historias que no nos son tan conocidos. La lectura de este libro suscitara la curiosidad tanto de los amantes de las plantas mas inveterados como la de aquellos que, simplemente, se han topado con esta impresionante obra por mera casualidad. Sea como fuere, no cabe duda del valor de los arboles ni de su papel en la vida de nuestro planeta tal como la conocemos.A lo largo de sus paginas encontrara un delicado equilibrio entre la investigacion y el relato. Junto a cada arbol se aportan fascinantes datos botanicos y se examina la distribucion geografica a lo largo del tiempo, a lo que le siguen deliciosas anecdotas sobre como han cambiado nuestra forma de vivir. La conciencia global de sus autores con respecto a la importancia que tienen los arboles para la humanidad se materializa en unas breves y encantadoras historias etnobotanicas que abarcan todos los continentes. Al mismo tiempo, son los propios arboles los que conforman la narracion, la cual se rige por el orden cronologico en el que se ha demostrado que han desempeñado un papel importante en la vida de la humanidad.

Desde la publicación de Sensibilidad e inteligencia en el mundo vegetal, Stefano Mancuso se ha convertido en un referente ineludible en el conocimiento de la fascinante realidad de las plantas. Suponen el 99,7% de la vida del planeta y sobrevivirian sin los animales mientras que nosotros desapareceriamos inmediatamente en un mundo sin ellas. Si en sus libros anteriores Stefano Mancuso nos descubria que las plantas son sensibles, se comunican e intercambian informacion, duermen, tienen memoria, cuidan de sus hijos, toman decisiones, resuelven problemas y nos mostraba lo que las plantas nos enseñan para resolver los multiples desafios del futuro, en este su nuevo libro se centra en algo que la evidencia parece negar: que las plantas se mueven y viajan. En cualquier espacio abandonado por el hombre, al poco ya crecen las plantas. Como llegan, como navegan alrededor del mundo, como llevan la vida a islas en medio del oceano, como consiguen crecer en lugares inaccesibles e inhospitos, como logran introducir la vida en suelos esteriles, como resistieron a la bomba atomica y al desastre de Chernobil, como son capaces de viajar en el tiempo (¡la ciencia ha conseguido revivir plantas a partir de semillas que habian permanecido en el hielo durante 39.000 años!). A todas estas preguntas da respuesta Stefano Mancuso en El increible viaje de las plantas. Y nos fascina con la narracion del incontenible impulso de difusion de la vida que ha llevado a las plantas a colonizar todos los habitats posibles de la Tierra.

Las plantas podrían perfectamente vivir sin nosotros, en cambio nosotros sin ellas nos extinguiríamos en un breve período de tiempo. Es más, en el planeta Tierra existe tan sólo un 0,3% de vida animal frente a un 99,7% de vida vegetal. Y sin embargo expresiones como vegetar o ser un vegetal indican en casi todas las lenguas unas condiciones de vida reducidas a la minima expresion.Cuando pensamos en las plantas, nos sentimos tentados a atribuirles dos caracteristicas: inmovilidad e insensibilidad. Pero investigaciones cientificas llevadas a cabo durante los ultimos cincuenta años han demostrado que las plantas son sensibles (es decir que estan dotadas no solo de los cinco sentidos que posee la especie humana sino de hasta quince sentidos mas), se comunican e intercambian informacion (entre ellas y con los animales), duermen, memorizan, cuidan de sus hijos, tienen su propia personalidad, toman decisiones e incluso son capaces de manipular a otras especies. ¿Como negar pues que tambien son inteligentes? Su capacidad para resolver los problemas que se les presentan ha sido probada por los estudios mas recientes.Este libro se adentra en el fascinante mundo de las plantas desde el rigor cientifico y al mismo tiempo usando un lenguaje accesible a cualquier lector. Y pone al descubierto lo mucho que les debemos y, mas aun, lo mucho que aun nos pueden enseñar.

Introduction This book teaches a theory and practice of two natural healing methods used in China. Every branch of Chinese medicine is holistic, but there are countless beds of possible holistic interconnection. To achieve greater synergy, they must be integrated in accordance with the principles contained herein. So these methods are used with greater advantages in China, with some variations, as you can learn them Chapter 1 and everywhere PART 2. The book is presented in two distinct parts, more closely intertwined, and follows the guidance of many wise professors who have the privilege of knowing over decades of study. Two central ideas were repeatedly found and, some teachers embodied them as formulas in a different way, the essential meanings were always the same. The first central idea is "To learn any practice or discipline, you need both a solid intellectual understanding and a solid foundation in its practical application." Everyone agrees that one s own practice (Qigong, Taiji, healing exercises, acupressure) or the application of the method (acupuncture, herbal medicine, food therapies) is the ultimate goal. Greater intellectual understanding may support greater practical ability, but it is valuable to the extent that it serves to promote that enterprise. If not, it may provide some interesting conversations, but it won t tangentially improve your health and life. A second central idea is "Mastery means mastery or basic." Basic principles are the reason for theory and practice. A broad, solid foundation provides stability for quality construction and growth. Even if you choose to build only one base, that will be your base in any time of difficulty. PART 1, "Teorias Fundamentais da Medicina Chinesa", presents the theoretical foundations of all Chinese medical science and philosophy. Embora is not as detailed as a medical book, it is quite extensive for two reasons. It provides the intellectual core necessary to understand and realize, and deeply familiarize the Western reader with a different way of seeing the world, from a Chinese perspective. The concepts and practices taught throughout this book arise from a cultural perspective and, if we want to learn to apply those practices in our daily lives, it will be necessary to make some effort to abandon our own cultural preconceits and see things with new eyes. The details in Part 1 are intended to facilitate that change in perception. A majority of PART 2, "Holistic Self-Care with Chinese Medicine," carefully teaches the practical foundations of two Chinese holistic self-care methods using the principles learned in Part 1 and offers plenty of room to grow as you become more adept at each. Doing practices regularly is the most important thing and, in the final analysis, leads to the domain, giving you the simple, most valuable and effective options to assume or control your health in a variety of natural and holistic ways. These are methods that you can use forever and that greatly reduce the likelihood of needing to see any doctor, whether Chinese or Western.

One of the worlds first tree-top scientists, Meg Lowman is both a pioneer in her field - she invented one of the first treetop walkways - and a tireless advocate for the planet. In a voice as infectious in its enthusiasm as in its practical optimism, The Arbornaut chronicles her irresistible story.From climbing solo hundreds of feet into Australias rainforests to measuring tree growth in the northeastern United States, from searching the redwoods of the Pacific coast for new life to studying leaf-eaters in Scotlands Highlands, from a bioblitz in Malaysia to conservation planning in India to collaborating with priests in Ethiopias last forests, Lowman launches us into the life and work of a scientist and ecologist. She also offers hope, specific plans and recommendations for action; despite devastation across the world, we can still make an immediate and lasting impact against climate change.

The Tree That Gives Back is a luminous collection of nature essays that explores the quiet intelligence of the natural world and the moral lessons it offers through reciprocity. Using the humble serviceberry tree as both metaphor and guide, the author reveals how every living thinghuman, plant, soil, and skyis bound in a web of giving and receiving.At its heart, this book is a meditation on gratitude as a natural law. The serviceberry feeds birds and bears, shades the forest floor, and blossoms long before other trees wake from winter. Its rhythm becomes a model for human living: give when you can, rest when you must, and trust that generosity sustains more than survivalit sustains meaning.Through clear, poetic essays, The Tree That Gives Back moves from one small plant to the vast systems it represents. Readers walk alongside the author through forests, fields, and city gardens, where acts of exchange are happening everywherebetween fungi and roots, between wind and seed, between people and the planet. Science meets spirit as ecology becomes a language of relationship.Each essay is built around a simple question: What does the earth give us, and what do we owe in return? The answers unfold through vivid observation, ecological insight, and personal reflection. The author writes of harvesting wild fruit without greed, of the ethics of eating, and of how gratitude can be an act of resistance in a culture built on taking.

Introduction We all have the need to nurture and care for other living things. Maybe you arent ready for a cat, dog, or fish, but bringing home a houseplant can fulfill that need. Place a plant on the windowsill and it will add living beauty to your home. Wake up every day and it will greet you as it cleans the air and improves your mood. Houseplants ask for so little but add so much life to a home. The care of that green friend falls solely on the owner. Being successful in that undertaking is important, so our hope is this book can help you keep your green roommate alive, healthy, and vibrant. There is no such thing as a natural green thumb. Many believe either you are born with one or not. The claim of having a brown or black thumb has had many dead plants placed at its doorstep. Yet having a green thumb is just a matter of paying attention to the needs of your plants and noticing when they are trying to tell you something. Killing a plant or two (or more) is not a crime, and can be a good learning experience. Dont be discouraged, as growing beautiful plants is easy if you have the time and pay attention to their specific needs, and this book will show you how to do that. Time restraints are another popular excuse as to why someone has no plants in their home. One easy plant can take less than five minutes a week to care for, and the benefits it brings will lead to a desire for more greenery in your life. Having plants continually die leads to frustration and possibly plastic plants. Not acceptable. When a few key components such as lighting preference, water, and placement are understood and correctly executed, your plants will thrive. Liking and being successful with plants has more rewards than are always apparent. Plants have been proven to clean the air around us. B. C. Wolverton, a NASA scientist, conducted many experiments in the 1980s and found that plants remove VOCsvolatile organic chemicalsfrom our indoor environments. These chemicals can come from carpet, paint, manufactured furniture, household cleaning products, and more. One plant can remove most of the VOCs from a 100-square-foot area. An important aspect of owning houseplants is the undeniable therapy that caring for plants affords us. In this uncertain, sometimes scary, fast-paced world, slowing down to care for something that is dependent on us can be therapeutic. Pick up a plant, remove dead leaves, check the growing medium for water, and wash the leaves with a soft cloth or sponge. Move quietly from plant to plant, or maybe you prefer to sing, hum, or talk to your plants. No judgment here. One plant may become many more when the time it takes to care for one plant isnt enough to untangle the knots from the day. Many professional people own large collections of plants for just this reason. Working with their plants takes them away from the enormous stress of their jobs. As Elvin McDonald wrote in his book Plants as Therapy, "I believe that plants have enormous potential for maintaining emotional stability and . . . improving the lives of human beings." Nothing truer can be said. Quite often, if you have a problem with a houseplant, you search online for information and help. But not every piece of information floating around on the Internet is true or pertinent to the specific plant for which you are caring. The information in this book will dispel the myths and misinformation about successfully raising houseplants. Plant societies are another good source of information. If you wish to learn as much as you can about a family of plants, such as cacti and other succulents, orchids, or African violets, join a plant society in your area. The people in these clubs have usually been growing those plants for a long time. Nothing beats the hands-on knowledge of people who have successfully grown a family of plants. Because they love their plants, they are more than willing to share their expertise. They want you to succeed with your plants.
