This podcast episode explores the concept of "15-minute cities," where residents can access essential amenities within a short distance of their homes. The idea promotes reduced car dependency, environmental sustainability, and improved quality of life. However, the implementation of 15-minute cities faces challenges such as conspiracy theories, political resistance, and the dominance of single-family zoning. Despite these obstacles, the episode emphasizes the importance of political will and community support in transforming cities towards a more sustainable future, as demonstrated by successful examples in Europe.
