Most people think of nature in the city as parks and zoos and dandelions pushing up through cracks in the sidewalk, but it is also asphalt streets, granite office buildings and mazes of underground pipes and cables. The materials of which the streets and buildings are constructed began as prehistoric jungles and ancient mountains. The systems that make a city work parallel those found among plants and animals. This book is designed to help people see the city as a whole, complete with plants, animals, people and city systems. It presents a unique way to explore cities and towns through treasure hunts, nature games, and dozens of imaginative activities--perfect for parents, teachers and group leaders. It teaches where and how to observe life science in a city. Chapters include:"Sharpening City Senses"; "Coping with Change, Creating Change"; three chapters on neighborhood adventures ("Wild Places," City Streets,""City People"); "Heading Downtown"; two chapters on city systems ("How Does a City Get Enough To Eat" and "Taking Care of Leftovers"); and "Taking Action." An appendix is included, entitled "Planning and Guiding Your Urban Safaris." A section on resources includes a bibliography, availability of a film entitled "Toast," and a list of outdoor education organizations. (CW)
