Much like human families, tree parents live together with their children, communicate with them, and support them as they grow, sharing nutrients with those who are sick or struggling and creating an ecosystem that mitigates the impact of extremes of heat and cold for the whole group. As a result of such interactions, trees in a family or community are protected and can live to be very old. In contrast, solitary trees, like street kids, have a tough time of it and in most cases die much earlier than those in a group.Drawing on groundbreaking new discoveries, Wohlleben presents the science behind the secret and previously unknown life of trees and their communication abilities; he describes how these discoveries have informed his own practices in the forest around him. As he says, a happy forest is a healthy forest, and he believes that eco-friendly practices not only are economically sustainable but also benefit the health of our planet and the mental and physical health of all who live on Earth.

    Key features include:- use of compatible perennials;- non-invasive planting techniques;- emphasis on biodiversity;- specifically adaptable to local climate, landscape, and soil conditions;- highly productive output of edibles.Now, picture your backyard as one incredibly lush garden, filled with edible flowers, bursting with fruit and berries, and carpeted with scented herbs and tangy salad greens. The visual impact is of Monet's palette, a wash of color, texture, and hue. But this is no still life. The flowers nurture endangered pollinators. Bright-featured songbirds feed on abundant berries and gather twigs for their nests.The plants themselves are grouped in natural communities, where each species plays a role in building soil, deterring pests, storing nutrients, and luring beneficial insects. And finally, you—good ol' homo sapiens—are an integral part of the scene. Your garden tools are resting against a nearby tree, and have a slight patina of rust, because this garden requires so little maintenance. You recline into a hammock to admire your work. You have created a garden paradise.This is no dream, but rather an ecological garden, which takes the principles of permaculture and applies them on a home-scale. There is nothing technical, intrusive, secretive, or expensive about this form of gardening. All that is required is some botanical knowledge (which is in this book) and a mindset that defines a backyard paradise as something other than a carpet of grass fed by MiracleGro.

    In this lively and topical introduction, Wartenberg reveals a vibrant mode of philosophical inquiry that addresses concerns at the heart of the existence of every human being. Wartenberg uses classic films, novels, and plays to present the ideas of now-legendary Existentialist thinkers from Nietzsche and Camus to Sartre and Heidegger and to explore central concepts, including Freedom, Anxiety, and the Absurd. Special attention is paid to the views of Simone de Beauvoir and Franz Fanon, who use the theories of Existentialism to address gender and colonial oppression.

    In his own lifetime, Suzuki has witnessed an explosion of scientific knowledge as well as a huge change in our relationship with the planet-a tripling of the world's population, a greatly increased ecological footprint through the global economy, and a huge growth in technological capacity. These changes have had a dire effect on Earth's ecosystems and consequently on our own well-being. To deal with this crisis, we must realize that the laws of nature have priority over the forces of economics and that the planet simply cannot sustain unfettered growth. We must also recognize the limits of scientific reductionism and the need to adopt a more holistic point of view. Perhaps most important, we must join together as a single species to respond to the problems we face. Suzuki ends by saying that change begins with each of us; all it takes is imagination and a faith in the inherent generosity of Mother Earth.Published in partnership with the David Suzuki Foundation. Also available in hardcover.

    The distressing decline of sea turtles in Pacific waters and their surprising recovery in the Atlantic illuminate what can go both wrong and right from our interventions, and teach us the lessons that can be applied to restore health to the world's oceans and its creatures. As Carl Safina's compelling natural history adventure makes clear, the fate of the astonishing leatherback turtle, whose ancestry can be traced back 125 million years, is in our hands.Writing with verve and color, Safina describes how he and his colleagues track giant pelagic turtles across the world's oceans and onto remote beaches of every continent. As scientists apply lessons learned in the Atlantic and Caribbean to other endangered seas, Safina follows leatherback migrations, including a thrilling journey from Monterey, California, to nesting grounds on the most remote beaches of Papua, New Guinea. The only surviving species of its genus, family, and suborder, the leatherback is an evolutionary marvel: a "reptile" that behaves like a warm-blooded dinosaur, an ocean animal able to withstand colder water than most fishes and dive deeper than any whale.In his peerless prose, Safina captures the delicate interaction between these gentle giants and the humans who are finally playing a significant role in their survival.

    In Gravity, he takes an enlightening look at three of the towering figures of science who unlocked many of the mysteries behind the laws of physics: Galileo, the first to take a close look at the process of free and restricted fall; Newton, originator of the concept of gravity as a universal force; and Einstein, who proposed that gravity is no more than the curvature of the four-dimensional space-time continuum.Graced with the author's own drawings, both technical and fanciful, this remarkably reader-friendly book focuses particularly on Newton, who developed the mathematical system known today as the differential and integral calculus. Readers averse to equations can skip the discussion of the elementary principles of calculus and still achieve a highly satisfactory grasp of a fascinating subject.Starting with a chapter on Galileo’s pioneering work, this volume devotes six chapters to Newton's ideas and other subsequent developments and one chapter to Einstein, with a concluding chapter on post-Einsteinian speculations concerning the relationship between gravity and other physical phenomena, such as electromagnetic fields.

    As the forerunner of such important books as Annie Dillard's Pilgrim at Tinker Creek, Edward Abbey's Desert Solitaire, and Robert Finch's The Primal Place, this classic work remains as relevant today as it was sixty-five years ago.

    However, once their predictions were compared to the results of experiments in the real world, it became clear that the principles of classical physics and mechanics were far from capable of explaining phenomena on the atomic scale. With this realization came the advent of quantum physics, one of the most important intellectual movements in human history. Today, quantum physics is everywhere: it explains how our computers work, how lasers transmit information across the Internet, and allows scientists to predict accurately the behavior of nearly every particle in nature. Its application continues to be fundamental in the investigation of the most expansive questions related to our world and the universe.However, while the field and principles of quantum physics are known to have nearly limitless applications, the fundamental reasons why this is the case are far less understood. In Quantum Physics: What Everyone Needs to Know, quantum physicist Michael G. Raymer distills the basic principles of such an abstract field, and addresses the many ways quantum physics is a key factor in today's science and beyond. The book tackles questions as broad as the meaning of quantum entanglement and as specific and timely as why governments worldwide are spending billions of dollars developing quantum technology research. Raymer's list of topics is diverse, and showcases the sheer range of questions and ideas in which quantum physics is involved. From applications like data encryption and quantum computing to principles and concepts like "quantum nonlocality" and Heisenberg's uncertainty principle, Quantum Physics: What Everyone Needs to Know is a wide-reaching introduction to a nearly ubiquitous scientific topic.

    Using photography as well as the author's own illustrations, Explore Your Nature invites readers to start at home, using all of their senses to notice the colors, sounds, smells, and textures of the trees, plants, animals, birds, insects, clouds, and other features that can be observed right outside their doorstep, no matter where they live. Prompts range from suggestions to note one daily exceptional nature image to learning to identify cloud types and the weather they bring, or creating a record of nature spottings on daily walks with the dog.

    They have done so since before recorded history. Flowers are used to celebrate all-important occasions, to express love, and are also the basis of global industries. Americans buy ten million flowers a day and perfumes are a worldwide industry worth $30 billion dollars annually. Yet, we know little about flowers, their origins, bizarre sex lives, or how humans relate and depend upon them.Stephen Buchmann takes us along on an exploratory journey of the roles flowers play in the production of our foods, spices, medicines, perfumes, while simultaneously bringing joy and health. Flowering plants continue to serve as inspiration in our myths and legends, in the fine and decorative arts, and in literary works of prose and poetry. Flowers seduce us—and animals, too—through their myriad shapes, colors, textures, and scents. And because of our extraordinary appetite for more unusual and beautiful “super flowers,” plant breeders have created such unnatural blooms as blue roses and black petunias to cater to the human world of haute couture fashion. In so doing, the nectar and pollen vital to the bees, butterflies, and bats of the world, are being reduced. Buchmann explains the unfortunate consequences, and explores how to counter them by growing the right flowers. Here, he integrates fascinating stories about the many colorful personalities who populate the world of flowers, and the flowers and pollinators themselves, with a research-based narrative that illuminates just why there is, indeed, a Reason for Flowers.

    In its companion volume River Notes, Lopez takes us into a different country where a nameless river flows through an animated world of herons, bears, and human beings.There is violence here, in the conflict of natural forces, in the people touching the river. There are landscapes, physical and spiritual, that we have not sensed, rituals we have not understood. Like the earlier peoples of our land, and like few American writers who have reentered this world, Barry Lopez respects the river and its imperatives, understands the language of cottonwoods and the salmon, and brings us in an extraordinary dance with a heron to the oneness with nature which is our heritage. ... [i]n these haunting, passionate stories Lopez brings us home to a deeply comforting unity with the natural world.From the first-edition dustjacket.
