Today in our environmental science lecture, we're discussing the impact of urban green spaces. A recent study in Melbourne found that adding more parks and trees in city centers can reduce local temperatures by up to 3 degrees Celsius during heatwaves. Interestingly, the effect was strongest not in large parks, but in small, shaded courtyards with water features. The study also showed that residents living within 200 meters of such green areas reported a 15% decrease in stress levels. However, the researchers noted that the cooling effect was limited to the immediate vicinity, and recommended integrating green corridors throughout the city rather than concentrating on a few large areas.
