Your garbage is going places you’d never imagine. What used to be sent to the local dump now may move hundreds of miles by truck and barge to its final resting place. Virtually all forms of pollution migrate, subjected to natural forces such as wind and water currents. The movement of garbage, however, is under human control. Its patterns of migration reveal much about power sharing among state, local, and national institutions, about the Constitution’s protection of trash transport as a commercial activity, and about competing notions of social fairness. In Garbage In, Garbage Out, Vivian Thomson looks at Virginia’s status as the second-largest importer of trash in the United States and uses it as a touchstone for exploring the many controversies around trash generation and disposal. Political conflicts over waste management have been felt at all levels of government. Local governments who want to manage their own trash have fought other local governments hosting huge landfills that depend on trash generated hundreds of miles away. State governments have tried to avoid becoming the dumping grounds for cities hundreds of miles away. The constitutional questions raised in these battles have kept interstate trash transport on Congress’s agenda since the early 1990s. Whether the resulting legislative proposals actually address our most critical garbage-related problems, however, remains in question. Thomson sheds much-needed light on these problems. Within the context of increased interstate trash transport and the trend toward privatization of waste management, she examines the garbage issue from a number of perspectives--including the links between environmental justice and trash management, a critical evaluation of the theoretical and empirical relationship between economic growth and environmental improvement, and highlighting the ways in which waste management practices in the US differ from those in the European Union and Japan. Thomson then provides specific, substantive recommendations for our own policymakers. Everything eventually becomes trash. As we explore the long, often surprising, routes our garbage takes, we begin to understand that it is something more than a mere nuisance that regularly "disappears" from our curbside. Rather, trash generation and management reflect patterns of consumption, political choices over whether garbage is primarily pollution or commerce, the social distribution of environmental risk, and how our daily lives compare with those of our counterparts in other industrialized nations.

Ever-expanding landfills, ocean gyres filled with floating plastic mush, endangered wildlife. Our garbage has become a massive and exponentially growing problem in modern society. Eco-entrepreneur Tom Szaky explores why this crisis exists and explains how can we solve it by eliminating the very idea of garbage. To outsmart waste, he says, we first have to understand it, then change how we create it, and finally rethink what we do with it. By mimicking nature and focusing on the value inherent in our by-products, we can transform the waste we can't avoid creating from useless trash to a useful resource. Szaky demonstrates that there is value in every kind of garbage, from used chewing gum to juice pouches to cigarette butts. After reading this mind-expanding book, you will never think about garbage the same way again.

“A galvanizing exposé” of America’s trash problem from plastic in the ocean to “wasteful packaging, bogus recycling, and flawed landfills and incinerators” (Booklist, starred review). Eat a take-out meal, buy a pair of shoes, or read a newspaper, and you’re soon faced with a bewildering amount of garbage. The United States is the planet’s number-one producer of trash. Each American throws out 4.5 pounds daily. But garbage is also a global problem. Today, the Pacific Ocean contains six times more plastic waste than zooplankton. How did we end up with this much rubbish, and where does it all go? Journalist and filmmaker Heather Rogers answers these questions by taking readers on a grisly and fascinating tour through the underworld of garbage. Gone Tomorrow excavates the history of rubbish handling from the nineteenth century to the present, pinpointing the roots of today’s waste-addicted society. With a “lively authorial voice,” Rogers draws connections between modern industrial production, consumer culture, and our throwaway lifestyle (New York Press). She also investigates the politics of recycling and the export of trash to poor countries, while offering a potent argument for change. “A clear-thinking and peppery writer, Rogers presents a galvanizing exposé of how we became the planet’s trash monsters. . . . [Gone Tomorrow] details everything that is wrong with today’s wasteful packaging, bogus recycling, and flawed landfills and incinerators. . . . Rogers exhibits black-belt precision.” —Booklist, starred review

Turning Simple Disciplines into Massive Success & Happiness

On Garbage is the first book to examine the detritus of Western culture in full range—not only material waste and ruin, but also residual or "broken" knowledge and the lingering remainders of cultural thought systems.

Out of sight, out of mind ... Into our trash cans go dead batteries, dirty diapers, bygone burritos, broken toys, tattered socks, eight-track cassettes, scratched CDs, banana peels.... But where do these things go next? In a country that consumes and then casts off more and more, what actually happens to the things we throw away? In Garbage Land, acclaimed science writer Elizabeth Royte leads us on the wild adventure that begins once our trash hits the bottom of the can. Along the way, we meet an odor chemist who explains why trash smells so bad; garbage fairies and recycling gurus; neighbors of massive waste dumps; CEOs making fortunes by encouraging waste or encouraging recycling-often both at the same time; scientists trying to revive our most polluted places; fertilizer fanatics and adventurers who kayak amid sewage; paper people, steel people, aluminum people, plastic people, and even a guy who swears by recycling human waste. With a wink and a nod and a tightly clasped nose, Royte takes us on a bizarre cultural tour through slime, stench, and heat-in other words, through the back end of our ever-more supersized lifestyles. By showing us what happens to the things we've "disposed of," Royte reminds us that our decisions about consumption and waste have a very real impact-and that unless we undertake radical change, the garbage we create will always be with us: in the air we breathe, the water we drink, and the food we consume. Radiantly written and boldly reported, Garbage Land is a brilliant exploration into the soiled heart of the American trash can.

This is the first book on "phylogenetic supertrees", a recent, but controversial development for inferring evolutionary trees. Rather than analyze the combined primary character data directly, supertree construction proceeds by combining the tree topologies derived from those data. This difference in strategy has allowed for the exciting possibility of larger, more complete phylogenies than are otherwise currently possible, with the potential to revolutionize evolutionarily-based research. This book provides a comprehensive look at supertrees, ranging from the methods used to build supertrees to the significance of supertrees to bioinformatic and biological research. Reviews of many the major supertree methods are provided and four new techniques, including a Bayesian implementation of supertrees, are described for the first time. The far-reaching impact of supertrees on biological research is highlighted both in general terms and through specific examples from diverse clades such as flowering plants, even-toed ungulates, and primates. The book also critically examines the many outstanding challenges and problem areas for this relatively new field, showing the way for supertree construction in the age of genomics. Interdisciplinary contributions from the majority of the leading authorities on supertree construction in all areas of the bioinformatic community (biology, computer sciences, and mathematics) will ensure that this book is a valuable reference with wide appeal to anyone interested in phylogenetic inference.

Explains how people create too much waste and how waste is now recycled and put into landfills.

An invitation for overachievers to discover what it means to rest as God's daughters without compromising their God-given design as doers. Are you a Martha who feels guilty for not being a Mary? Do you want to sit at Jesus’s feet as Mary did—but you feel the need to get things done? In Made Like Martha, Katie M. Reid invites you to exchange try-hard striving for hope-filled freedom without abandoning your doer’s heart in the process. Through her own story and rich biblical illustrations, Katie reminds you that it’s not important whether you sit and listen or stand and work. What matters is that your spiritual posture is one of a beloved daughter who knows she doesn’t need to earn God’s love. Your desire to get things done is not something to temper but something to embrace as you serve from a place of strength and peace—knowing Christ already did His most important work for you on the cross. With “It Is Finished” activities at the end of each chapter and a fiveweek Bible study included, Made Like Martha helps you find rest from striving even as you celebrate your God-given design to “do.” “Made Like Martha will infuse your life with a fresh perspective as you learn both to embrace your God-given personality and also discover how—and when—to rest and retreat.” —Karen Ehman, Proverbs 31 Ministries speaker and New York Times bestselling author of Keep It Shut
