Book Description
The U.S. Navy established an ecological monitoring program to determine whether electric and magnetic fields from extremely low frequency (ELF) communications systems influenced plant and animal populations near the transmitting facilities. Although some of the researchers believe that a few biological changes might have occurred, they concluded that the results do not indicate significant adverse ecological effects. This book evaluates the 11 ecological studies of the Navy's monitoring program and examines the adequacy of experimental design, the data collection and analysis, and the soundness of the conclusions. It also addresses whether the monitoring program was capable of detecting subtle effects due to ELF exposure and examines the biological changes observed by some program researchers, such as enhanced tree growth.

Book Description
World human population is expected to reach upwards of 9 billion by 2050 and then level off over the next half-century. How can the transition to a stabilizing population also be a transition to sustainability? How can science and technology help to ensure that human needs are met while the planet's environment is nurtured and restored? Our Common Journey examines these momentous questions to draw strategic connections between scientific research, technological development, and societies' efforts to achieve environmentally sustainable improvements in human well being. The book argues that societies should approach sustainable development not as a destination but as an ongoing, adaptive learning process. Speaking to the next two generations, it proposes a strategy for using scientific and technical knowledge to better inform future action in the areas of fertility reduction, urban systems, agricultural production, energy and materials use, ecosystem restoration and biodiversity conservation, and suggests an approach for building a new research agenda for sustainability science. Our Common Journey documents large-scale historical currents of social and environmental change and reviews methods for "what if" analysis of possible future development pathways and their implications for sustainability. The book also identifies the greatest threats to sustainabilityâ€"in areas such as human settlements, agriculture, industry, and energyâ€"and explores the most promising opportunities for circumventing or mitigating these threats. It goes on to discuss what indicators of change, from children's birth-weights to atmosphere chemistry, will be most useful in monitoring a transition to sustainability.
