Little changes can have big effects. The premise in this joyful, uplifting book is that not only big governments, but city governments and even individuals can take steps right now to improve their own cities, where ever they are. Some of the short mini-essays highlight successful initiatives, or the unique aspects of certain cities which improve them; for example, the rivers and streams in Paris or Seoul, or the distinct architecture of Barcelona or Moscow. It encourages city leaders to plan for more walking, bike riding, and public transportation, and to add trees and green spaces. But even smaller initiatives can make a big difference; for example, the woman who shares a beautiful nativity scene every year, the town that adopted a local sculpture and periodically redecorates it, or local festivals and markets. As the author proves through his wonderful anecdotes, the heart of a city is made of individuals who know and love it, who care for it and work and live in it. With obvious fondness and even delight for the topic, this lovely little guide expresses the joy felt in cities, great and small, that stay human because of these small points of care.
