Book Description
Dr. Smil is the world's authority on nitrogenous fertilizer. The industrial synthesis of ammonia from nitrogen and hydrogen has been of greater fundamental importance to the modern world than the invention of the airplane, nuclear energy, space flight, or television. The expansion of the world's population from 1.6 billion people in 1900 to today's six billion would not have been possible without the synthesis of ammonia. In Enriching the Earth, Vaclav Smil begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts to expand natural nitrogen flows through mineral and synthetic fertilizers. The core of the book is a detailed narrative of the discovery of ammonia synthesis by Fritz Haber—a discovery scientists had sought for over one hundred years—and its commercialization by Carl Bosch and the chemical company BASF. Smil also examines the emergence of the large-scale nitrogen fertilizer industry and analyzes the extent of global dependence on the Haber-Bosch process and its biospheric consequences. Finally, it looks at the role of nitrogen in civilization and, in a sad coda, describes the lives of Fritz Haber and Carl Bosch after the discovery of ammonia synthesis.

Book Description
A “poignant [and] powerful” novel about a 1920s Midwestern community in the aftermath of a devastating tornado (The New Yorker). In March 1925, the worst tornado in the nation’s history will descend without warning on the small town of Marah, Illinois. By nightfall, hundreds will be homeless and hundreds more will lie in the streets, dead or grievously injured. Only one man, Paul Graves, will still have everything he started the day with—his family, his home, and his business, all miraculously intact. This “absolutely gorgeous” novel follows Paul Graves and his young family in the year after the storm as they struggle to comprehend their own fate and that of their devastated town (The New York Times). They watch helplessly as Marah tries to resurrect itself from the ruins and as their friends and neighbors begin to wonder how one family, and only one, could be exempt from terrible misfortune. As the town begins to recover, the family miscalculates the growing resentment and hostility around them with tragic results, in an “extraordinarily moving” portrayal of survivor’s guilt and the frenzy of bereavement following a disaster (Financial Times). “All the big themes are here—chance, fate, loyalty, revenge, guilt, jealousy . . . Inspired by actual events surrounding the 1925 Tri-State tornado, the worst in U.S. history, Southwood’s poignantly penetrating examination of the psychic cost of survival is breathtaking in its depth of understanding.” —Booklist (starred review) “What’s most exciting about Southwood’s debut is her prose, which is reminiscent of Willa Cather’s in its ability to condense the large, ineffable melancholy of the plains into razor-sharp images.” —The Daily Beast

Book Description
Why does the church engage in missions? Where in the Bible do we find support for this work? These questions have been asked and answered by many throughout the centuries, though rarely does the investigation span across the entire canon of Scripture. In this study Newkirk explores the breadth and depth of biblical teaching concerning God's mission for his people and the church's call to spread the gospel to the ends of the earth. By beginning with creation and ending with new creation, this study reveals that rather than simply deriving from a few "missions verses," the church's call to missions is grounded in the full spectrum of biblical revelation.

Book Description
Biological nitrogen fixation provides more than 50% of the total annual input of the essential element nitrogen to world agriculture. Thus, it is of immense agronomic importance and critical to food supplies, particularly in developing countries. This book, with chapters authored by internationally renowned experts, provides a comprehensive and detailed account of the fascinating history of the process - including the surprising discoveries of molybdenum-independent nitrogenases and superoxide-dependent nitrogenase; a review of Man's attempts to emulate the biological process - most successfully with the commercially dominant Haber-Bosch process; and the current state of the understanding art with respect to the enzymes - called nitrogenases - responsible for biological nitrogen fixation. The initial chapters use a historical approach to the biological and industrial processes, followed by an overview of assay methodologies. The next set of chapters focuses on the classical enzyme, the molybdenum nitrogenase, and details its biosynthesis, structure, composition, and mechanism of action as well as detailing both how variants of its two component proteins are constructed by recombinant DNA technology and how computational techniques are being applied. The sophisticated chemical modelling of the metal-containing clusters in the enzyme is reviewed next, followed by a description of the two molybdenum-independent nitrogenases - first, the vanadium-containing enzyme and then the iron-only nitrogenase - together with some thoughts as to why they exist! Then follows an up-to-date treatment of the clearly "non-classical" properties of the superoxide-dependent nitrogenase, which more closely resembles molybdenum-containing hydroxylases and related enzymes, like nitrate reductase, that it does the other nitrogenases. Each chapter contains an extensive list of references. This book is the self-contained first volume of a comprehensive seven-volume series. No other available work provides the up-to-date and in-depth coverage of this series and this volume. This book is intended to serve as an indispensable reference work for all scientists working in this area, including agriculture and the closely related metals-in-biology area; to assist students to enter this challenging area of research; and to provide science administrators easy access to vital relevant information.

Book Description
A powerful movement is happening in farming today—farmers are reconnecting with their roots to fight climate change. For one woman, that’s meant learning her tribe’s history to help bring back the buffalo. For another, it’s meant preserving forest purchased by her great-great-uncle, among the first wave of African Americans to buy land. Others are rejecting monoculture to grow corn, beans, and squash the way farmers in Mexico have done for centuries. Still others are rotating crops for the native cuisines of those who fled the “American wars” in Southeast Asia. In Healing Grounds, Liz Carlisle tells the stories of Indigenous, Black, Latinx, and Asian American farmers who are reviving their ancestors’ methods of growing food—techniques long suppressed by the industrial food system. These farmers are restoring native prairies, nurturing beneficial fungi, and enriching soil health. While feeding their communities and revitalizing cultural ties to land, they are steadily stitching ecosystems back together and repairing the natural carbon cycle. This, Carlisle shows, is the true regenerative agriculture – not merely a set of technical tricks for storing CO2 in the ground, but a holistic approach that values diversity in both plants and people. Cultivating this kind of regenerative farming will require reckoning with our nation’s agricultural history—a history marked by discrimination and displacement. And it will ultimately require dismantling power structures that have blocked many farmers of color from owning land or building wealth. The task is great, but so is its promise. By coming together to restore these farmlands, we can not only heal our planet, we can heal our communities and ourselves.

Book Description
A revolutionary guide to designing humane, eco-conscious homes, buildings, and cities of the future. It is estimated that the earth's population will expand to an unprecedented nine billion people over the next century. This explosion in population is predicted to place further stress on our environment, deplete our natural resources, and lead to increases in anxiety and depression due to overcrowding. In this visionary and uplifting book, Teresa Coady offers readers new hope. Rebuilding Earth is her blueprint for designing and building the cities, buildings, and homes of tomorrow, resulting in more conscious, sustainable, and humane living. Coady shows us how we can shift from an outdated Industrial-Age framework to a more humane, Digital-Age framework. This revolutionary approach will enable communities to harness various forms of green energy and reduce the amount of material needed to build infrastructure while contributing to a healthier planet (and society). We can then experience a new sense of purpose, health, and happiness. Meaningful and lasting change, the author tells us, can only come through designing interconnected communities that are vibrant, resilient, and communal. Unlike most predictions of doom and gloom, Coady presents a refreshingly optimistic view of humanity and its future. This book will appeal to those in the construction, design and development finance industries, as well as anyone interested in improving their lives through understanding the connections between the environment and health.
