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 2 degrees Celsius. Moreover, these spaces help absorb rainwater, reducing flood risk. Interestingly, the study also noted that residents living within 500 meters of a green space reported lower stress levels and increased physical activity. However, researchers emphasize that maintenance is crucial; poorly kept areas may attract pests and deter usage. Therefore, city planners should prioritize sustainable design and community involvement.
