Harvard University Press The Great Acceleration: An Environmental History of the Anthropocene since 1945
The Earth has entered a new age—the Anthropocene—in which humans are the most powerful influence on global ecology. Since the mid-twentieth century, the accelerating pace of energy use, greenhouse gas emissions, and population growth has thrust the planet into a massive uncontrolled experiment. The Great Acceleration explains its causes and consequences, highlighting the role of energy systems, as well as trends in climate change, urbanization, and environmentalism.More than any other factor, human dependence on fossil fuels inaugurated the Anthropocene. Before 1700, people used little in the way of fossil fuels, but over the next two hundred years coal became the most important energy source. When oil entered the picture, coal and oil soon accounted for seventy-five percent of human energy use. This allowed far more economic activity and produced a higher standard of living than people had ever known—but it created far more ecological disruption.We are now living in the Anthropocene. The period from 1945 to the present represents the most anomalous period in the history of humanity’s relationship with the biosphere. Three-quarters of the carbon dioxide humans have contributed to the atmosphere has accumulated since World War II ended, and the number of people on Earth has nearly tripled. So far, humans have dramatically altered the planet’s biogeochemical systems without consciously managing them. If we try to control these systems through geoengineering, we will inaugurate another stage of the Anthropocene. Where it might lead, no one can say for sure.

Island Press Health and Community Design: The Impact Of The Built Environment On Physical Activity
Health and Community Design is a comprehensive examination of how the built environment encourages or discourages physical activity, drawing together insights from a range of research on the relationships between urban form and public health. It provides important information about the factors that influence decisions about physical activity and modes of travel, and about how land use patterns can be changed to help overcome barriers to physical activity. Chapters examine: the historical relationship between health and urban form in the United States; why urban and suburban development should be designed to promote moderate types of physical activity; the divergent needs and requirements of different groups of people and the role of those needs in setting policy; how different settings make it easier or more difficult to incorporate walking and bicycling into everyday activities; A concluding chapter reviews the arguments presented and sketches a research agenda for the future.
