Today in our environmental science lecture, we'll discuss the impact of urban green spaces. A recent study in Melbourne found that adding parks and community gardens can reduce local temperatures by up to 3 degrees Celsius. However, the key factor isn't the size of the green area, but its distribution. Small, evenly spaced green pockets are more effective than one large central park. Additionally, trees with broad leaves provide better shade than those with narrow leaves, and they also absorb more carbon dioxide. The study suggests that city planners should prioritize planting along streets and in residential areas rather than focusing solely on large recreational parks.
