By the bestselling author of Four Fish and American Catch, an eye-opening investigation of the history, science, and business behind omega-3 fatty acids, the "miracle compound" whose story is intertwined with human health and the future of our planet Omega-3 fatty acids have long been celebrated by doctors and dieticians as key to a healthy heart and a sharper brain. In the last few decades, that promise has been encapsulated in one of America's most popular dietary supplements. Omega-3s are today a multi-billion dollar business, and sales are still growing apace--even as recent medical studies caution that the promise of omega-3s may not be what it first appeared. But a closer look at the omega-3 sensation reveals something much deeper and more troubling. The miracle pill is only the latest product of the reduction industry, a vast, global endeavor that over the last century has boiled down trillions of pounds of marine life into animal feed, fertilizer, margarine, and dietary supplements. The creatures that are the victims of that industry seem insignificant to the untrained eye, but turn out to be essential to the survival of whales, penguins, and fish of all kinds, including many that we love to eat. Behind these tiny molecules is a big story: of the push-and-pull of science and business; of the fate of our oceans in a human-dominated age; of the explosion of land food at the expense of healthier and more sustainable seafood; of the human quest for health and long life at all costs. James Beard Award-winning author Paul Greenberg probes the rich and surprising history of omega-3s--from the dawn of complex life, when these compounds were first formed; to human prehistory, when the discovery of seafood may have produced major cognitive leaps for our species; and on to the modern era, when omega-3s may point the way to a bold new direction for our food system. With wit and boundless curiosity, Greenberg brings us along on his travels--from Peru to Antarctica, from the Canary Islands to the Amalfi Coast--to reveal firsthand the practice and repercussions of our unbalanced way of eating. Rigorously reported and winningly told, The Omega Principle is a powerful argument for a more deliberate and forward-thinking relationship to the food we eat and the oceans that sustain us.

A collection of the most advanced and authoritative agricultural-economic research in the face of increasing water scarcity. Agriculture has been critical in the development of the American economy. Except in parts of the western United States, water access has not been a critical constraint on agricultural productivity, but with climate change, this may no longer be the case. This volume highlights new research on the interconnections between American agriculture, water resources, and climate change. It examines climatic and geologic factors that affect the agricultural sector and highlights historical and contemporary farmer responses to varying conditions and water availability. It identifies the potential effects of climate change on water supplies, access, agricultural practices, and profitability, and analyzes technological, agronomic, management, and institutional adjustments. Adaptations such as new crops, production practices, irrigation technologies, water conveyance infrastructure, fertilizer application, and increased use of groundwater can generate both social benefits and social costs, which may be internalized with various institutional innovations. Drawing on both historical and present experiences, this volume provides valuable insights into the economics of water supply in American agriculture as climate change unfolds.

This book serves as a foundational reference of U.S. land settlement and early agricultural policy, a comprehensive journey through the evolution of 20th century agricultural policy, and a detailed guide to the key agricultural policy issues of the early 21st century. This book integrates the legal, economic and political concepts and ideas that guided U.S. agricultural policy from colonial settlement to the 21st century, and it applies those concepts to the policy issues agriculture will face over the next generation. The book is organized into three sections. Section one introduces the main themes of the book, explores the pre-Columbian period and early European settlement, and traces the first 150 years of U.S. agricultural policy starting with the post revolution period and ending with the “golden age” of agriculture in the early 20th century. Section two outlines that grand bargain of the 1930s that initiated the modern era of government intervention into agricultural markets and traces this policy evolution to the early days of the 21st century. The third section provides an in-depth examination of six policy issues that dominate current policy discussions and will impact policy decisions for the next generation: trade, environment/conservation, commodity checkoff programs, crop insurance, biofuels, and domestic nutrition programs.

The New York Times–bestselling classic set amid the mountains and streams of early twentieth-century Montana, “as beautiful as anything in Thoreau or Hemingway” (Chicago Tribune). When Norman Maclean sent the manuscript of A River Runs Through It and Other Stories to New York publishers, he received a slew of rejections. One editor, so the story goes, replied, “it has trees in it.” Today, the title novella is recognized as one of the great American tales of the twentieth century, and Maclean as one of the most beloved writers of our time. The finely distilled product of a long life of often surprising rapture—for fly-fishing, for the woods, for the interlocked beauty of life and art—A River Runs Through It has established itself as a classic of the American West filled with beautiful prose and understated emotional insights. Based on Maclean’s own experiences as a young man, the book’s two novellas and short story are set in the small towns and mountains of western Montana. It is a world populated with drunks, loggers, card sharks, and whores, but also one rich in the pleasures of fly-fishing, logging, cribbage, and family. By turns raunchy and elegiac, these superb tales express, in Maclean’s own words, “a little of the love I have for the earth as it goes by.” “Maclean’s book—acerbic, laconic, deadpan—rings out of a rich American tradition that includes Mark Twain, Kin Hubbard, Richard Bissell, Jean Shepherd, and Nelson Algren.” —New York Times Book Review Includes a new foreword by Robert Redford, director of the Academy Award–winning film adaptation

This book discusses the karst and pseudokarst of the Upper Midwest, USA, consisting of the states of Minnesota, Wisconsin, Iowa, and Illinois—the first regional synthesis in 40 years. Starting with an overview of the regional geology of what is largely glaciated fluviokarst and paleokarst developed on Paleozoic carbonates, but including other lithologies such as the St. Peter Sandstone and the Ft. Dodge Gypsum, the caves, springs, sinkholes, and karst hydrogeology of each state are described. Special attention is devoted to the region’s longest caves: Coldwater Cave, Mystery Cave, and the Minnesota Cave Preserve caves. Application of tools such as data loggers and LiDAR, with new conceptual models such as hypogenic speleogenesis, has been transformative here. Special topics include lead and zinc mining in the Driftless Area, vertebrate and invertebrate cave fauna near the Laurentide ice limit, the impact and policies of nutrient and herbicide intensive modern agriculture on karst, and paleoclimate studies. The discovery, exploration, institutional history of caving organizations, and show caves of the Upper Midwest, from the year 1700 onwards, are brought up to date. The top 10 historical paradigms of cave and karst science in the Midwest are reviewed. Perspectives on paleontology, archeology, and Native American rock art are included.

Norman Maclean’s “A River Runs through It”: The Search for Beauty is the first book-length study of Norman Maclean or any of his works. Since the publication of “A River Runs through It” in 1976, readers and critics have considered it to be one of the most carefully crafted stories in American literature, in terms of both its structure and its style. The beauty of the story came with much hard work. This study traces Maclean’s revisions through four handwritten drafts and three typescripts, quoting extensively from previously unpublished material. The analysis of Maclean’s composition process lays the foundation for original and detailed discussions of other aspects of Maclean’s craft, such as his approach to genre and style. The study publishes for the first time the complete text of the notes that Maclean wrote after the first draft of “A River Runs through It.”
