Today, in our environmental science lecture, we'll discuss urban green spaces. Recent studies show that city parks can reduce local temperatures by up to 5 degrees Celsius during heatwaves. Additionally, they improve air quality by absorbing pollutants. However, the key factor in maximizing these benefits is the density of trees, not just the total area of grass. For instance, a small park with many trees is more effective than a large open field. Therefore, urban planners should prioritize planting a variety of native species, as they require less water and support local wildlife. This approach also cuts maintenance costs by about 30%.
