Book Description
Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Book Description
Starting in late 2006, commercial migratory bee-keepers along the East Coast of the United States began reporting sharp declines in their honey bee colonies. Because of the severity and unusual circumstances of these colony declines, scientists named this phenomenon colony collapse disorder (CCD). Reports indicate that bee-keepers in most states have been affected. Overall, the number of managed honey bee colonies dropped an estimated 35.8% and 31.8% in the winters of 20062008, and 28.6% in 2009. To date, the precise reasons for colony losses are not yet known. Honey bees are the most economically valuable pollinators of agricultural crops world-wide. Scientists at universities and the USDA frequently assert that bee pollination is involved in about one-third of the U.S. diet, and contributes to the production of a wide range of fruits, vegetables, tree nuts, forage crops, some field crops, and other specialty crops. The monetary value of honey bees as commercial pollinators in the U.S. is estimated at $1520 billion annually. This book provides an overview of the importance of honey bee pollination to U.S. agricultural production and the extent and symptoms of CCD and how it differs from previous honey bee colony losses.Also discussed are the policy options and actions that Congress has taken to address this issues.

Book Description
In 2006, commercial migratory beekeepers along the East Coast of the United States began reporting sharp declines in their honey bee colonies. Because of the severity and unusual circumstances of these colony declines, scientists have named this phenomenon Colony Collapse Disorder (CCD). Reports indicate that beekeepers in 35 states have been affected. Overall, bee colony losses averaged about 30% in 2007. Reports for 2008 show continued declines with estimated average annual losses nation-wide approaching 35%. Honey bees are the most economically valuable pollinators of agricultural crops world-wide. Many scientists at universities and the U.S. Department of Agriculture (USDA) frequently assert that bee pollination is involved in about one-third of the U.S. diet, and contributes to the production of a wide range of fruits, vegetables, tree nuts, forage crops, some field crops, and other speciality crops. The monetary value of honey bees as commercial pollinators in the United States is estimated at about $15 billion annually. Honey bee colony losses are not uncommon. However, current losses seem to differ from past situations in that colony losses are occurring mostly because bees are failing to return to the hive (which is largely uncharacteristic of bee behaviour); bee colony losses have been rapid; colony losses are occurring in large numbers; and the reason(s) for these losses remains largely unknown. The potential causes of CCD, as reported by the scientists who are researching this phenomenon, include but may not be limited to parasites, mites, and disease loads in the bees and brood; emergence of new or newly more virulent pathogens; poor nutrition among adult bees; lack of genetic diversity and lineage of bees; level of stress in adult bees (e.g., transportation and confinement of bees, overcrowding, or other environmental or biological stressors); chemical residue/contamination in the wax, food stores, and/or bees; a combination of these and/or other factors. In 2007, the House held two subcommittee hearings to review the recent honey bee colony declines and to address concerns about pollinator health. In 2008, the Senate hosted a briefing on pollinators and their role in agricultural security. Various policy options were discussed at these hearings and briefings, including increasing federal funding for research and monitoring, providing technical support and assistance for beekeepers, and emphasising the importance of pollinator diversity and sustaining wild and native pollinator species.

Book Description
This book was written by undergraduate students at The Ohio State University (OSU) who were enrolled in the class Introduction to Environmental Science. The chapters describe some of Earth's major environmental challenges and discuss ways that humans are using cutting-edge science and engineering to provide sustainable solutions to these problems. Topics are as diverse as the students, who represent virtually every department, school and college at OSU. The environmental issue that is described in each chapter is particularly important to the author, who hopes that their story will serve as inspiration to protect Earth for all life.

Book Description
In 2005, beekeepers in the United States began observing a mysterious and disturbing phenomenon: once-healthy colonies of bees were suddenly collapsing, leaving behind empty hives full of honey and pollen. Over the following decade, widespread honeybee deaths—some of which have come to be called Colony Collapse Disorder (CCD)—have continued to bedevil beekeepers and threaten the agricultural industries that rely on bees for pollination. Scientists continue to debate the causes of CCD, yet there is no clear consensus on how to best solve the problem. Vanishing Bees takes us inside the debates over widespread honeybee deaths, introducing the various groups with a stake in solving the mystery of CCD, including beekeepers, entomologists, growers, agrichemical companies, and government regulators. Drawing from extensive interviews and first-hand observations, Sainath Suryanarayanan and Daniel Lee Kleinman examine how members of each group have acquired, disseminated, and evaluated knowledge about CCD. In addition, they explore the often-contentious interactions among different groups, detailing how they assert authority, gain trust, and build alliances. As it explores the contours of the CCD crisis, Vanishing Bees considers an equally urgent question: what happens when farmers, scientists, beekeepers, corporations, and federal agencies approach the problem from different vantage points and cannot see eye-to-eye? The answer may have profound consequences for every person who wants to keep fresh food on the table.

Book Description
The Digital Age was expected to usher in an era of clean production, an alternative to smokestack industries and their pollutants. But as environmental journalist Elizabeth Grossman reveals in this penetrating analysis of high tech manufacture and disposal, digital may be sleek, but it's anything but clean. Deep within every electronic device lie toxic materials that make up the bits and bytes, a complex thicket of lead, mercury, cadmium, plastics, and a host of other often harmful ingredients. High Tech Trash is a wake-up call to the importance of the e-waste issue and the health hazards involved. Americans alone own more than two billion pieces of high tech electronics and discard five to seven million tons each year. As a result, electronic waste already makes up more than two-thirds of the heavy metals and 40 percent of the lead found in our landfills. But the problem goes far beyond American shores, most tragically to the cities in China and India where shiploads of discarded electronics arrive daily. There, they are "recycled"-picked apart by hand, exposing thousands of workers and community residents to toxics. As Grossman notes, "This is a story in which we all play a part, whether we know it or not. If you sit at a desk in an office, talk to friends on your cell phone, watch television, listen to music on headphones, are a child in Guangdong, or a native of the Arctic, you are part of this story." The answers lie in changing how we design, manufacture, and dispose of high tech electronics. Europe has led the way in regulating materials used in electronic devices and in e-waste recycling. But in the United States many have yet to recognize the persistent human health and environmental effects of the toxics in high tech devices. If Silent Spring brought national attention to the dangers of DDT and other pesticides, High Tech Trash could do the same for a new generation of technology's products.
