Today in our environmental science lecture, we'll discuss urban green spaces. Recent studies show that city parks not only improve air quality but also reduce stress levels among residents. However, the key factor in their effectiveness is accessibility. A park located within a 10-minute walk from homes is more likely to be used regularly. Interestingly, smaller neighborhood gardens often have higher usage rates than larger central parks, because they are closer to where people live. This suggests that planners should prioritize distributed small green areas over a few large ones.
