📖 Reading Passage

The concept of sustainable urban development has evolved significantly over the past decades, moving beyond mere environmental concerns to encompass economic and social dimensions. While early initiatives focused primarily on reducing carbon emissions and preserving green spaces, contemporary frameworks emphasize the integration of affordable housing, efficient public transportation, and community engagement. Research indicates that cities adopting holistic sustainability strategies often experience improved quality of life and economic resilience. However, critics argue that such approaches can lead to gentrification, displacing low-income residents. Therefore, successful implementation requires careful policy design that balances ecological goals with social equity, ensuring that the benefits of sustainability are shared across all demographics.
