Today in our environmental science lecture, we'll discuss urban green spaces. A recent study in Melbourne found that adding more parks and tree-lined streets can reduce local temperatures by up to 4 degrees Celsius during heatwaves. However, the benefits are not just physical. Researchers also noted a 15% decrease in stress levels among residents who lived within a 10-minute walk of a green area. Interestingly, the study highlighted that smaller, scattered gardens were more effective than one large central park, because they provided easier access for more people. So, city planners should prioritize distributing green spaces evenly.
