Good morning, class. Today we're discussing the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed 2,000 residents over five years. Participants who lived within 300 meters of a park or garden reported 20% lower stress levels. Interestingly, the benefit was stronger for older adults and those with sedentary jobs. However, the researchers noted that the quality of the green space mattered more than its size. For instance, areas with diverse trees and quiet walking paths had a greater positive effect than large, open lawns. The study suggests that city planners should prioritize small, well-designed pocket parks in dense neighborhoods.
