Garbage in the Garden State (CERES: Rutgers Studies in History)
by Jordan P. HowellGarbage in the Garden State is the only book to examine the history of waste management in New Jersey. The state has played a pioneering role in the overall trajectory of waste management in the US. Howell's book is unique in the way that it places the contemporary challenges of waste management into their proper historical context – for instance, why does the system for recycling seem to work so poorly? Why do we have so many landfills in New Jersey, but also simultaneously not enough landfills or incinerators? Howell acknowledges that New Jersey is sometimes imagined, particularly by non-New Jerseyans, as a giant garbage dump for New York and Philadelphia. But every place has had to struggle with the challenges of waste management. New Jersey's trash history is in fact more interesting and more important than most. New Jersey’s waste history includes intensive planning, deep-seated political conflict, organized crime, and literally every level of state and federal judiciary. It is a colorful history, to say the least, and one that includes a number of firsts with regard to recycling, comprehensive planning, and the challenging economics of trash.
Garbage Wars: The Struggle For Environmental Justice In Chicago (Urban And Industrial Environments Ser.)
by David PellowIn Garbage Wars, the sociologist David Pellow describes the politics of garbage in Chicago. He shows how garbage affects residents in vulnerable communities and poses health risks to those who dispose of it. He follows the trash, the pollution, the hazards, and the people who encountered them in the period 1880-2000. What unfolds is a tug of war among social movements, government, and industry over how we manage our waste, who benefits, and who pays the costs. Studies demonstrate that minority and low-income communities bear a disproportionate burden of environmental hazards. Pellow analyzes how and why environmental inequalities are created. He also explains how class and racial politics have influenced the waste industry throughout the history of Chicago and the United States. After examining the roles of social movements and workers in defining, resisting, and shaping garbage disposal in the United States, he concludes that some environmental groups and people of color have actually contributed to environmental inequality. By highlighting conflicts over waste dumping, incineration, landfills, and recycling, Pellow provides a historical view of the garbage industry throughout the life cycle of waste. Although his focus is on Chicago, he places the trends and conflicts in a broader context, describing how communities throughout the United States have resisted the waste industry's efforts to locate hazardous facilities in their backyards. The book closes with suggestions for how communities can work more effectively for environmental justice and safe, sustainable waste management.
Garbology: Our Dirty Love Affair with Trash
by Edward HumesA Pulitzer Prize-winning journalist takes readers on a surprising tour of America's biggest export, our most prodigious product, and our greatest legacy: our trash <P><P> The average American produces 102 tons of garbage across a lifetime and $50 billion in squandered riches are rolled to the curb each year. But our bins are just the starting point for a strange, impressive, mysterious, and costly journey that may also represent the greatest untapped opportunity of the century. <P> In Garbology, Edward Humes investigates trash--what's in it; how much we pay for it; how we manage to create so much of it; and how some families, communities, and even nations are finding a way back from waste to discover a new kind of prosperity. Along the way , he introduces a collection of garbage denizens unlike anyone you've ever met: the trash-tracking detectives of MIT, the bulldozer-driving sanitation workers building Los Angeles' Garbage Mountain landfill, the artists residing in San Francisco's dump, and the family whose annual trash output fills not a dumpster or a trash can, but a single mason jar.<P> Garbology reveals not just what we throw away, but who we are and where our society is headed. Waste is the one environmental and economic harm that ordinary working Americans have the power to change--and prosper in the process.<P> Garbology is raising awareness of trash consumption and is sparking community-wide action through One City One Book programs around the country.<P> It is becoming an increasingly popular addition to high school and college syllabi and is being adopted by many colleges and universities for First Year Experience programs.
Garden Plants Taxonomy: Volume 1: Ferns, Gymnosperms, and Angiosperms (Monocots)
by Bijan DehganHorticulture has remained far behind in understanding of botanical principles. Recent phylogenetic (DNA-based) reorganization of higher plants has revolutionized taxonomic treatments of all biological entities, even when morphology does not completely agree with their organization. This book is an example of applying principals of botanical phylogenetic taxonomy to assemble genera, species, and cultivars of 200 vascular plant families of ferns, gymnosperms, and angiosperms that are cultivated for enhancement of human living space; homes, gardens, and parks. The emphases are on cultivated species but examples of some plants are often shown in the wild and in landscapes. In providing descriptions, it is assumed that students and other interested individuals have no background in general botany (plant characteristics), or nomenclature. Fundamental features of all plant groups discussed are fully illustrated by original watercolor drawings or photographs. Discussion of the families is grounded on recent botanical phylogenetic treatments, which is based on common ancestry (monophyly). Of course, phylogenetic taxonomy is not a new concept, and was originally based on morphological characteristics; it is the DNA-based phylogeny that has revolutionized modern biological classifications. In practical terms, this book represents the horticultural treatment that corresponds to phylogenetic-based botanical taxonomy, to which is added cultigens and cultivated genera and species. Hence, the harmony between horticultural and botanical taxonomy. This book covers phylogenetic-based taxonomy of Ferns, Gymnosperms, and Angiosperms (Monocots). A companion volume covers Angiosperms (Eudicots).

Gardening When It Counts: Growing Food in Hard Times (Mother Earth News Books for Wiser Living #5)
by Steve SolomonThe decline of cheap oil is inspiring increasing numbers of North Americans to achieve some measure of backyard food self-sufficiency. In hard times, the family can be greatly helped by growing a highly productive food garden, requiring little cash outlay or watering. Currently popular intensive vegetable gardening methods are largely inappropriate to this new circumstance. Crowded raised beds require high inputs of water, fertility and organic matter, and demand large amounts of human time and effort. But, except for labor, these inputs depend on the price of oil. Prior to the 1970s, North American home food growing used more land with less labor, with wider plant spacing, with less or no irrigation, and all done with sharp hand tools. But these sustainable systems have been largely forgotten. Gardening When It Counts helps readers rediscover traditional low-input gardening methods to produce healthy food. Designed for readers with no experience and applicable to most areas in the English-speaking world except the tropics and hot deserts, this book shows that any family with access to 3-5,000 sq. ft. of garden land can halve their food costs using a growing system requiring just the odd bucketful of household waste water, perhaps two hundred dollars worth of hand tools, and about the same amount spent on supplies -- working an average of two hours a day during the growing season.

Gardens of New Spain
by William W. DunmireWhen the Spanish began colonizing the Americas in the late fifteenth and sixteenth centuries, they brought with them the plants and foods of their homeland—wheat, melons, grapes, vegetables, and every kind of Mediterranean fruit. Missionaries and colonists introduced these plants to the native peoples of Mexico and the American Southwest, where they became staple crops alongside the corn, beans, and squash that had traditionally sustained the original Americans. This intermingling of Old and New World plants and foods was one of the most significant fusions in the history of international cuisine and gave rise to many of the foods that we so enjoy today. Gardens of New Spain tells the fascinating story of the diffusion of plants, gardens, agriculture, and cuisine from late medieval Spain to the colonial frontier of Hispanic America. Beginning in the Old World, William Dunmire describes how Spain came to adopt plants and their foods from the Fertile Crescent, Asia, and Africa. Crossing the Atlantic, he first examines the agricultural scene of Pre-Columbian Mexico and the Southwest. Then he traces the spread of plants and foods introduced from the Mediterranean to Spain’s settlements in Mexico, New Mexico, Arizona, Texas, and California. In lively prose, Dunmire tells stories of the settlers, missionaries, and natives who blended their growing and eating practices into regional plantways and cuisines that live on today in every corner of America.

The Gas Mask in Interwar Germany: Visions of Chemical Modernity (Science in History)
by Peter ThompsonExploring the history of the gas mask in Germany from 1915 to the eve of the Second World War, Peter Thompson traces how chemical weapons and protective technologies like the gas mask produced new relationships to danger, risk, management and mastery in the modern age of mass destruction. Recounting the apocalyptic visions of chemical death that circulated in interwar Germany, he argues that while everyday encounters with the gas mask tended to exacerbate fears, the gas mask also came to symbolize debates about the development of military and chemical technologies in the Weimar Republic and the Third Reich. He underscores how the gas mask was tied into the creation of an exclusionary national community under the Nazis and the altered perception of environmental danger in the second half of the twentieth century. As this innovative new history shows, chemical warfare and protection technologies came to represent poignant visions of the German future.
