Urban planning should be of interest for everyone who cares about their environment, or wants to make it a better place to live in.

    Traditionally, urban planning was focused strongly on efficiency, such as for instance, designing transportation networks that made the best use of scarce resources. But increasingly, urban planning has come to be a discipline that makes more livable communities, ones which have a happy balance between commercial, retail, residential housing, parks, open spaces, walkable neighborhoods, and the preservation of history and cultural monuments.

    Sustainability is another major issue in contemporary urban planning, with more attention being paid to communities that derive their energy sources from renewable sources, instead of contributing to depleting energy resources that are finite.

    Urban planners also can work to intelligently modify the problems inherent in cities that were born and developed in the decades and centuries that preceded urban planning. Modern planners were able to work around these problems with imaginative ideas.
