Today we're discussing the impact of urban green spaces. A recent study in Melbourne found that adding trees and parks to city areas can reduce local temperatures by up to 4 degrees Celsius. However, the effect is strongest when green spaces are connected, forming corridors. Interestingly, the study also noted that residents near these spaces reported lower stress levels, but only when the spaces were well-maintained. The researchers suggest that city planners should prioritize creating linked networks of small parks rather than one large central park, as this benefits more neighborhoods.
