Good morning, class. Today we'll continue our discussion on urban planning. One key concept is the '15-minute city', where residents can access most daily needs within a short walk or bike ride from home. However, a recent study in Melbourne found that while this model works well for services like grocery stores and parks, it often fails for specialized medical facilities and large employment centers. The researcher, Dr. Emily Chen, noted that lower-income neighborhoods tend to have fewer of these essential services, making the 15-minute goal less achievable there. She suggests that planners should prioritize public transport links to these areas rather than just focusing on local amenities.
