| [00:04.36]American officials are seeking ways for cities to grow without expanding into surrounding open space. [00:14.00]They are trying to rebuild the centers of older industrial cities. [00:19.91]And they want to help people use less resources such as fuel and water than are being used now. [00:28.84]A new book tells about how some cities in Europe have found answers to these problems. [00:37.25]The book is called, "Green Urbanism, Learning from European Cities." [00:43.76]Timothy Beatley wrote the book. [00:46.52]He is professor of urban and environmental planning at the University of Virginia in Charlottesville. [00:54.60]The book tells about the experiences of twenty-five cities in eleven European countries. [01:02.46]Some of the cities in the study are large, such as Copenhagen, Denmark and Stockholm, Sweden. [01:10.61]Some are small, such as Freiburg, Germany and Leiden, the Netherlands. [01:17.66]Cities have been described as organisms that use up resources and produce wastes that pollute the environment. [01:26.49]Sustainable cities try to restrict their use of resources such as energy and water [01:33.47]and to pollute less so people in the future will be able to survive. [01:39.19]Cities that were part of Mister Beatley's study have some things in common. [01:45.43]Growth takes place within the city limits. [01:49.71]This means the centers of these cities are fully developed, not left partly empty as in most American cities. [01:58.94]Buildings are reused or taller ones are built as the city grows. [02:04.11]This protects the open space or farmland outside the city. [02:09.96]Sustainable cities try to make it possible for people to easily move around without using cars. [02:18.55]Reducing the use of cars reduces the pollution produced by cars. [02:24.35]Many cities support the use of bicycles to replace cars. [02:30.23]Some cities build separate safe paths for bike riders within the city limits. [02:36.97]Other cities like Copenhagen provide public bicycles. [02:42.19]A bicycle can be used to ride from one place to another and left for someone else to ride. [02:49.51]And sustainable cities are green. City officials keep open areas in the city for parks and children's playgrounds. [02:58.86]Trees are planted along city streets. [03:01.84]Some cities teach people how to plant on rooftops and in window boxes. [03:07.01]Professor Beatley says American cities can learn from sustainable European cities about providing for people |
