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. However, the key finding is about their size: smaller, scattered gardens are more beneficial for biodiversity than one large park, because they create diverse habitats. Professor Lin from Melbourne noted that residents near these small spaces reported a 30% increase in daily physical activity. Yet, funding often prioritizes large projects, which is a mistake we need to address.
