Today in our environmental science lecture, we're discussing urban green spaces. Recent studies show that city parks not only improve air quality but also reduce noise pollution. Interestingly, researchers found that the cooling effect of a park can extend up to 200 meters beyond its boundary. However, the most significant benefit is mental health: people living within a 10-minute walk of a park report 40% lower stress levels. Yet, despite these advantages, many cities allocate less than 15% of their budget to maintaining such areas. So, we need to rethink urban planning priorities.
