Why are "new urbanist communities" being developed across America and what are their effects on human impact within a community?

NEW URBANISM is the most important planning movement this century, and is about creating a better future for us all. It is an international movement to reform the design of the built environment, and is about raising our quality of life and standard of living by creating better places to live.

New Urban focuses on human-scaled urban design.

This helps reduce pollution, keep congestion down, and helps residents live a healthier, more active lifestyle.
