For much of its history, human population growth increased at a glacial pace. The demographic rate only soared about 200 years ago, climaxing in the period 1950-2000. In that 50-year span, the population grew more than it had in the previous 5000 years. Though these raw numbers are impressive, they conceal the fact that the growth rate of population topped out in the 1960s. The apparent population boom may be approaching a population bust, despite our coexistence with more than seven billion people. In On the Cusp, economist Charles Pearson explores the meaning of this population trend from the arc of demographic growth to decline. He reviews Thomas Malthus's famous 1798 argument that human population would exceed the earth's carrying capacity, and explains why this surfaces periodically when birth rates strongly exceed 2.1 children per household. Analyzing population trends through dual lenses - demography and economics - Pearson examines the potential opportunities and challenges of population decline and aging. In many industrialized countries, the combination of an aging population and considerable food security may call for policies that boost fertility, immigration, and worker participation, reform pension schemes, and ease concern over moderating rates of population and economic growth. Sharp and occasionally funny, Pearson's research has thought-provoking implications for future public policies. Pearson ends his analysis with a mildly hopeful conclusion, noting that both the rich and the poor face a new demographic order. Bold and comprehensive, general readers and students alike will find On the Cusp an informative and engaging read.

In March 2011 the Fukushima nuclear power plant (NPP) in Japan was hit by an earthquake and subsequent tsunami which resulted in the release of significant amounts of radioactive material.

Bringing together ecology, evolutionary moral psychology, and environmental ethics, J. Baird Callicott counters the narrative of blame and despair that prevails in contemporary discussions of climate ethics and offers a fresh, more optimistic approach. Whereas other environmental ethicists limit themselves to what Callicott calls Rational Individualism in discussing the problem of climate change only to conclude that, essentially, there is little hope that anything will be done in the face of its "perfect moral storm" (in Stephen Gardiner's words), Callicott refuses to accept this view. Instead, he encourages us to look to the Earth itself, and consider the crisis on grander spatial and temporal scales, as we have failed to in the past. Callicott supports this theory by exploring and enhancing Aldo Leopold's faint sketch of an Earth ethic in "Some Fundamentals of Conservation in the Southwest," a seldom-studied text from the early days of environmental ethics that was written in 1923 but not published until 1979 after the environmental movement gathered strength.

Global populations have grown rapidly in recent decades, leading to ever increasing demands for shelter, resources, energy and utilities. Coupled with the worldwide need to achieve lower impact buildings and conservation of resources, the need to achieve sustainability in urban environments has never been more acute. This book critically reviews the fundamental issues and applied science, engineering and technology that will enable all cities to achieve a greater level of metropolitan sustainability, and assist nations in meeting the needs of their growing urban populations.
Part one introduces key issues related to metropolitan sustainability, including the use of both urban metabolism and benefit cost analysis. Part two focuses on urban land use and the environmental impact of the built environment. The urban heat island effect, redevelopment of brownfield sites and urban agriculture are discussed in depth, before part three goes on to explore urban air pollution and emissions control. Urban water resources, reuse and management are explored in part four, followed by a study of urban energy supply and management in part five. Solar, wind and bioenergy, the role of waste-to-energy systems in the urban infrastructure, and smart energy for cities are investigated. Finally, part six considers sustainable urban development, transport and planning.
With its distinguished editor and international team of expert contributors, Metropolitan sustainability is an essential resource for low-impact building engineers, sustainability consultants and architects, town and city planners, local/municipal authorities, and national and non-governmental bodies, and provides a thorough overview for academics of all levels in this field.

Now more than ever we are facing pressing world challenges of energy (identifying alternate energy), food (ensuring the food supply), water (providing clean water), and human health (enabling individualized medicine); and to solve these challenges will require chemistry and the related chemical sciences. Integrating sustainability into everything we do from instituting responsible operations, to selecting partners for change and innovating sustainable solutions. Industry needs academe to prepare their graduates to ascend the ladder with skill and agility. This can only be done by integrating sustainability expeditiously into chemistry curricula.

This book makes a serious effort at bringing forth and synergistically combining the concepts of green chemistry, sustainability and nanotechnology and should motivate scientistsat all levels to think clearly and seriously about creating and optimizing novel and sustainable green approaches to nanotechnology. The chapters in this book can be divided into three broad categories: 1) Advancement in research on pollution control through the green chemistry principles of nanotechnology; 2) Emergence of nanomaterials in widespread applications in various scientific fields, including but not limited to sensors and catalysts; 3) Extension of research into nanotechnology and green nanotechnology at a rapid pace. Review articles on the individual aspects of these diverse and complementary topics have become important resources for researchers, industry leaders, and regulators, both nationally and internationally. This book contains a few chapters associated with these particular themes, and provides glimpses of the many difficulties and challenges faced by those who seek to not only understand but also regulate the new nanomaterials. Nanotechnology represents a unique field of science, and necessitates new and novel sustainable approaches to create usable end products for the market place with the primary goal of yielding less adverse effects upon both human health and the environment.

Rivers are significant geomorphological agents, they show an amazing diversity of form and behaviour and transfer water and sediment from the land surface to the oceans. This book examines how river systems respond to environmental change and why this understanding is needed for successful river management. Highly dynamic in nature, river channels adjust and evolve over timescales that range from hours to tens of thousands of years or more, and are found in a wide range of environments. This book provides a comprehensive overview of recent developments in river channel management, clearly illustrating why an understanding of fluvial geomorphology is vital in channel preservation, environmentally sensitive design and the restoration of degraded river channels. It covers: flow and sediment regimes: flow generation; flow regimes; sediment sources, transfer and yield channel processes: flow characteristics; processes of erosion and sediment transport; interactions between flow and the channel boundary; deposition channel form and behaviour: controls on channel form; channel adjustments; floodplain development; form and behaviour of alluvial and bedrock channels response to change: how channels have responded to past environmental change; impacts of human activity; reconstructing past changes river management: the fluvial hydrosystem; environmental degradation; environmentally sensitive engineering techniques; river restoration; the role of the fluvial geomorphologist. Fundamentals of Fluvial Geomorphology is an indispensable text for undergraduate students. It provides straightforward explanations for important concepts and mathematical formulae, backed up with conceptual diagrams and appropriate examples from around the world to show what they actually mean and why they are important. A colour plate section also shows spectacular examples of fluvial diversity.

The Protection of Subjects in Human Research rule by the USEPA, including the establishment of the Human Studies Review Board (HSRB), has resulted in changes to both study design and study evaluation processes, particularly with respect to ethical considerations. Non-Dietary Human Exposure andRisk Assessment is a compilation of the presentations given in a symposium of the same name at the 238th ACS National Meeting in Washington D.C. The purpose of the symposium was to provide a forum for scientists from industry, academia, and government to share investigative methods used to generate data for use in non-dietary human risk assessments and to share methodology for performing and evaluating those assessments.
This compilation is intended to provide the reader with a concise overview of the current status of both the scientific and regulatory aspects of non-dietary human exposure and risk assessment as applied to pesticides. It is the hope of the editors that it will also be the starting point for discussions leading to the further refinement of study and risk assessment design, data evaluation, and regulatory harmonization.
Three major areas are covered in this symposium edition. The first area is regulatory issues including the development of the Protection of Subjects in Human Research rule and the HSRB, statistical procedures involved in designing human exposure studies, handling of the data generated in those studies, and quality assurance processes related to worker exposure studies. The second area, study design, includes processes for the identification and recruitment of volunteers for human exposure studies, overviews of several studies that have been recently performed, the development of procedures for evaluating the resulting data by Regulatory Agencies, and efforts towards international cooperation in the generation and use of exposure data. The final area, methodology, includes examples of the development of methods for the analysis of samples generated in non-dietary human exposure studies with particular emphasis on the use of hyphenated techniques and the development of a model for determining greenhouse exposures that is currently being used in Europe.
