Book Description
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Pages : 132
Book Description
This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.
Battling for Manassas

Book Description
When the Disney Company ended months of controversy in 1995 by deciding against locating its historic theme park near the National Battlefield Park in Manassas, Virginia, advocates of historic preservation had won their own battle but perhaps not their war. Few places exemplify the problems of historic preservation as urgently as Manassas. The site of this Civil War battle, also known as Bull Run, has been encroached upon by plans for an interstate highway, a cemetery, a shopping mall, and two theme parks. As Washington continues its sprawl into the Virginia countryside, pressure will surely mount to develop the remaining open land surrounding the battlefield. The history of Manassas battlefield illustrates that the Disney controversy is only the latest in a long line of skirmishes over historic preservation and use. Battling for Manassas is a record of the struggles to preserve the park over the past fifty years. First commissioned as a report by the National Park Service, this book tells how park managers, government officials, preservationists, developers, and concerned citizens have managed to find compromises that would protect the site while accommodating changes in the surrounding community. Joan Zenzen's narrative places these highly publicized preservation conflicts within the framework of the park's history. She traces the efforts to preserve this Civil War battleground as it has slowly been surrounded by suburban development and discloses how issues involving visitors' facilities, recreation use of parkland, non-park-related usage, and encroachment on park boundaries by commercial interests have all come into play. Her study draws on interviews with many individuals who have been influential in the park's history&—including park service officials, members of Congress, representatives of preservation groups, developers, and local officials&—as well as on archival documents that help explain the nature of each controversy. She also shows that the Park Service's reluctance to conduct long-range planning following the controversy over Marriott's proposed Great America theme park contributed to later battles over development. Battling for Manassas is the story of how one site has garnered national attention and taught Americans valuable lessons about the future of historic preservation. It demonstrates to everyone interested in the Civil War that, with only 58 of 384 sites currently under Park Service jurisdiction, what has happened at Manassas might well occur on other historic grounds threatened by development or neglect.
Climate change: Unpacking the burden on food safety
Author: Food and Agriculture Organization of the United Nations Publisher: Food & Agriculture Org.
ISBN: 9251322937
Category : Technology & Engineering
Languages : en
Pages : 176
Book Description
Climate change is causing unprecedented damage to our ecosystem. Increasing temperatures, ocean warming and acidification, severe droughts, wildfires, altered precipitation patterns, melting glaciers, rising sea levels and amplification of extreme weather events have direct implications for our food systems. While the impacts of such environmental factors on food security are well known, the effects on food safety receive less attention. The purpose of Climate change: Unpacking the burden on food safety is to identify and attempt to quantify some current and anticipated food safety issues that are associated with climate change. The food safety hazards considered in the publication are foodborne pathogens and parasites, harmful algal blooms, pesticides, mycotoxins and heavy metals with emphasis on methylmercury. There is also, a dedicated section on the benefits of forward-looking approaches such as horizon scanning and foresight, which will not only aid in anticipating future challenges in a shifting global food safety landscape, but also help build resilient food systems that can be continually updated as more knowledge is assimilated. By building a more widespread and better understanding of the consequences climate change has on food safety, it is hoped that this document will aid in fostering stronger international cooperation in making our food safer by reducing the global burden of these concerns.

Book Description
The implications of biodiversity loss for the global environment have been widely discussed, but only recently has attention been paid to its direct and serious effects on human health. Biodiversity loss affects the spread of human diseases, causes a loss of medical models, diminishes the supplies of raw materials for drug discovery and biotechnology, and threatens food production and water quality. Biodiversity and Human Health brings together leading thinkers on the global environment and biomedicine to explore the human health consequences of the loss of biological diversity. Based on a two-day conference sponsored by the National Institutes of Health, the National Science Foundation, and the Smithsonian Institution, the book opens a dialogue among experts from the fields of public health, biology, epidemiology, botany, ecology, demography, and pharmacology on this vital but often neglected concern. Contributors discuss the uses and significance of biodiversity to the practice of medicine today, and develop strategies for conservation of these critical resources. Topics examined include: the causes and consequences of biodiversity loss emerging infectious diseases and the loss of biodiversity the significance and use of both prescription and herbal biodiversity-derived remedies indigenous and local peoples and their health care systems sustainable use of biodiversity for medicine an agenda for the future In addition to the editors, contributors include Anthony Artuso, Byron Bailey, Jensa Bell, Bhaswati Bhattacharya, Michael Boyd, Mary S. Campbell, Eric Chivian, Paul Cox, Gordon Cragg, Andrew Dobson, Kate Duffy-Mazan, Robert Engelman, Paul Epstein, Alexandra S. Fairfield, John Grupenhoff, Daniel Janzen, Catherine A. Laughin, Katy Moran, Robert McCaleb, Thomas Mays, David Newman, Charles Peters, Walter Reid, and John Vandermeer. The book provides a common framework for physicians and biomedical researchers who wish to learn more about environmental concerns, and for members of the environmental community who desire a greater understanding of biomedical issues.
