    They are being told that buying organic foods, unprocessed and sourced from small local farms, is the most healthful and sustainable option. Now, Robert Paarlberg reviews the evidence and finds abundant reason to disagree. He delineates the ways in which global food markets have in fact improved our diet, and how industrial farming has recently turned green, thanks to GPS-guided precision methods that cut energy use and chemical pollution. He makes clear that America's serious obesity crisis does not come from farms, or from food deserts, but instead from food swamps created by food companies, retailers, and restaurant chains. And he explains how, though animal welfare is lagging behind, progress can be made through continued advocacy, more progressive regulations, and perhaps plant-based imitation meat. He finds solutions that can make sense for farmers and consumers alike and provides a road map through the rapidly changing worlds of food and farming, laying out a practical path to bring the two together.

    Avian Flu. Ebola. Every year, the infectious disease changes—but the threat remains the same. We've all read the headlines. We all know the score. Our interconnected world is at a uniquely dangerous moment. The potential for an epidemic progressing to a catastrophic level has never been higher. The question is: what are we going to do about it? What happens when medicine fails and society has to make the hard choices to take the severe steps necessary to stop the inevitable? Mandatory quarantine. A month ago, the term seemed like something out of science fiction. Today, we know better. Quarantine might be the only thing that will keep us alive. Q is the story of a regular cop, Benjamin Grady, who suddenly finds himself on the front line of an unyielding, terrifying epidemic. His job is simple—to quarantine the Probables, those most likely to be carrying a deadly disease. But Grady quickly learns that no amount of training, no amount of lectures from the experts at the CDC or the military infectious disease specialists can prepare him for a society on the verge of losing the war to a microscopic, unrelenting scourge. Ripped from the headlines, meticulously researched, Q lays bare the truth behind the quarantine laws that are already on the books, and what it would mean to implement them on a national scale. At this very moment, we are closer to the edge than ever before. Whether we realize it or not, America is one poorly contained infected airliner, one disease-ridden subway car away from full-scale martial law. Q is a true story. It just hasn't happened yet.

    Armed with maps and cheerful curiosity, he travels from the oil-drunk boomtown of Fort McMurray, Alberta (a.k.a. Fort McMoney), down to the empty North Dakota plains, where mountains of pipe lie in wait for the torrent of crude that could soon start to flow if, as expected, the White House approves the controversial plan to turn on the spigots that will deliver oil from Canada directly to the Gulf of Mexico. Along the way, Horwitz meets a cavalcade of characters, including ranchers who either love or loathe the idea of oil flowing beneath their land, “rig pigs” and “cement heads” who are eager to make a buck in the tar fields, and strippers and other local entrepreneurs who are ready to help them spend it. He drives miles of lonesome road in his quest to understand what this pipeline means to everyone involved—from Native Americans to environmentalists to industry bureaucrats. He sees firsthand not only how an oil spill can devastate acres of rich farmland but how a town can be saved by an influx of new jobs. Over homemade farm dinners and countless tavern beers, Horwitz realizes that there are no easy answers, no right or wrong, no heroes or villains. The questions surrounding America’s energy future go beyond pat declarations about independence from foreign oil or destruction of Mother Earth. They go, some believe, to the very meaning of freedom. ABOUT THE AUTHOR Tony Horwitz is a Pulitzer Prize–winning journalist who spent a decade as a foreign correspondent, mainly covering wars and conflicts in the Middle East, Africa, and Europe for the “Wall Street Journal.” His books include the bestsellers “Confederates in the Attic,” “Blue Latitudes,” “Baghdad Without a Map,” and “A Voyage Long and Strange.” His most recent, “Midnight Rising,” was named a New York Times Notable Book of 2011 and one of the year’s ten best books by Library Journal and won the 2012 William Henry Seward Award for excellence in Civil War biography.

PRAISE FOR TONY HORWITZ “Horwitz wears himself lightly, and is extraordinarily good at drawing out strangers. Cheerfully energetic, he goes where a less intrepid reporter would not.” —Roy Blount, Jr., The New York Times “Like travel writer Bill Bryson, Horwitz has a penchant for meeting colorful characters and getting himself into bizarre situations.” —The Christian Science Monitor “Horwitz has an ear for a good yarn and an instinct for the trail leading to an entertaining anecdote.” —The Washington Post “A trip with Horwitz is as good as it gets.” —The Charlotte Observer

    de Camp has the trick of being able to show technology engaging in feats as full of derring-do as those of Hannibal's army. History as it should be told."--Isaac Asimov, The New York Times Book Review The Pyramids of Giza, the Parthenon of Greece, the Great Wall of China, the Colosseum of Rome. Today, we stand in awe before these wonders of the ancient world. They hold our history and the deepest secrets of our past in their hidden recesses.In The Ancient Engineers, L. Sprague de Camp delves into the heart of the mystery. He introduces us to the master builders who had the vision, the power, and the passion to reach for the clouds and touch the heavens. We share in some of the greatest technological triumphs of all time--triumphs of the human mind, imagination, and spirit.

    It’s what I won a Pulitzer Prize for, years ago. I go to epidemics, wars, places where people are struggling to cope with disasters, and I carefully log the accounts and events, trying to represent the lives and experiences of others. The position of “outsider” is emotionally safe, even as agonizing events unfold. But I could not distance myself from the extraordinary sequence of events that fell on America, and especially my home town of New York City, in 2001. A decade later I am still trying to understand how the attacks on the World Trade Center and the anthrax mailings affected me, and those I love. I heard the first jet slam into the north tower of the World Trade Center, and from the rooftop of my apartment building watched the second commercial jet veer towards lower Manhattan, change its trajectory, and slice across the upper floors of the south tower. I was standing on the Manhattan anchorage of the Brooklyn Bridge when the first tower crumbled like a deflated accordion, spewing dust and debris in every direction and crushing the life out of thousands of people within. And a month later, as people started falling ill from inhalation of anthrax spores, one of the nation’s top bioterrorism experts called me to warn that I was a likely target: Stop opening your mail. The flow of these events, from the hijacking of four commercial jets on September 11th to the November death of an anthrax-infected Connecticut villager, took most of the world population from a remarkably united emotional and political place, to a deeply divided, frustrated, angry position. The arc of the response matters: It ultimately determined the course of historic events worldwide and tore America asunder, the people having lost trust in their government and without it, most forms of social cohesion. By the end of the winter of 2002 the arc had completed, from spectacular unity and confidence in governance to deep division and accusations of American arrogance. Through the frustrated anthrax investigations and drumbeats of war, the global community, especially Americans, moved in just a few months’ time from collectivism to fragmentation.This book is structured in two parts. The first, THE END OF THE AGE OF INNOCENCE, is written in the present tense, describing almost hourly the events that unfolded primarily in Washington DC and New York City over 120 days in the fall and winter of 2001 and 2002. Each day is a chapter that opens with the actual diary entry that I sent on that date to a list of friends all over the world. The entry is followed by a detailed breakdown of the day’s events, unfolding like a novel.Part two, NEW WORLD ORDER, details the repercussions of these events, transformations of critical government institutions, public health disasters, and what, in particular, the specter of terrorism meant for the American people. Revelations abound in this book, including:• The bizarre chemistry of The Plume that rose from the burning crushed World Trade Center for four months, endangering the health of hundreds of thousands of New Yorkers.• Evidence that al-Qaeda may have been behind the anthrax mailings.• Devastating spending and restructuring followed the attacks, leaving the nation less prepared for terrorism ten years later, and broke.• Each incident following the opening of anthrax-laden letters reveals countless errors and misjudgments.• There was no “weapons-grade anthrax” in those letters – a finding with profound health and political implications.

    His conception of the universe pervades Christian theology. Knowledge of his thought is necessary to understand Bacon, Galileo, and the modern scientific view of nature, as well as Dante and many passages from Chaucer, Shakespeare, and Milton. Many phrases such as liberal education and theory contrasted with practice originated with this student of Plato and tutor of Alexander the Great.Writing to inform the beginner and stimulate the expert, eminent scholar A. E. Taylor presents a searching analysis of Aristotle's thought, including classification of the sciences; formal logic; theory of knowledge; matter and form; the four causes; God; physics; biology; sensation; ethics; theory of the state; and the fine arts. He also considers Aristotle's provincialism, errors regarding the nervous system and astronomy, and defense of slavery.The Giants of Philosophy is a series of dramatic presentations, in understandable language, of the concerns, questions, interests, and overall world view of history's greatest philosophers. Special emphasis on clear and relevant explanations gives you a new arsenal of insights toward living a better life.

    If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible. In California, wildfires now rage year-round, destroying thousands of homes. Across the US, "500-year" storms pummel communities month after month, and floods displace tens of millions annually.This is only a preview of the changes to come. And they are coming fast. Without a revolution in how billions of humans conduct their lives, parts of the Earth could become close to uninhabitable, and other parts horrifically inhospitable, as soon as the end of this century.In his travelogue of our near future, David Wallace-Wells brings into stark relief the climate troubles that await--food shortages, refugee emergencies, and other crises that will reshape the globe. But the world will be remade by warming in more profound ways as well, transforming our politics, our culture, our relationship to technology, and our sense of history. It will be all-encompassing, shaping and distorting nearly every aspect of human life as it is lived today.Like An Inconvenient Truth and Silent Spring before it, The Uninhabitable Earth is both a meditation on the devastation we have brought upon ourselves and an impassioned call to action. For just as the world was brought to the brink of catastrophe within the span of a lifetime, the responsibility to avoid it now belongs to a single generation.
