The United States is in the midst of a crisis of energy consumption and environmental degradation, whose costs will become increasingly clear in coming years as our population skyrockets and our cities continue to sprawl. Unchecked development in multicity regions has damaged the natural environment, snarled traffic, and caused us to burn petroleum at a rate far greater than the rest of the world. Smart Growth in a Changing World documents the United States’ hidden growth crisis and shows how balanced transportation and natural resource preservation can put urban development on a sustainable path, as well as making it more efficient and equitable for consumers. This groundbreaking volume on the urban dilemma features case studies on transportation and conservation in Florida and the Northeast as well as proposals for hazard migration, green cities, mixed-use centers, walkable neighborhoods, and planning policies at the national level. As our global competitors are investing in smart growth strategies such as high-speed rail lines and regional rapid transit, this timely book calls for a similarly forward-thinking new development approach in the United States.
