Today's lecture focuses on the impact of urban green spaces. Recent studies show that parks and community gardens can significantly reduce local temperatures by up to 5 degrees Celsius during heatwaves. Additionally, they improve air quality by absorbing pollutants. Interestingly, researchers found that residents living within 300 meters of a green space reported lower stress levels and increased physical activity. However, the benefits depend on accessibility and maintenance. For instance, poorly maintained parks may discourage use, while well-designed spaces with seating and lighting encourage social interaction. Therefore, city planners should prioritize equitable distribution rather than just total area.
