Sydney is the largest city in Australia and the center of the country's economic activity. It has a comfortable climate, easy access to beaches, good public transportation, and a cosmopolitan and ethnically varied population with relatively few racial tensions. Because of these attractions, Sydney is considered one of the best cities in the world in which to live. However, it is not without its problems. There are very high levels of traffic congestion, which in turn contribute to severe air pollution. Water shortages are a growing threat in such a dry climate, and as the city grows so do its demands on a limited water supply. Hardworking text, inquisitive interviews, and a strong visual content displaying full-color maps and specially commissioned photographs are featured in Sydney, which shows how this global city is working to meet its challenges.
