Today, in our environmental science lecture, we'll discuss the impact of urban green spaces. Recent studies show that parks and community gardens can reduce city temperatures by up to 5 degrees Celsius. However, the key factor is not just the number of trees, but their distribution. Researchers found that small, evenly distributed green areas are more effective than a few large parks. Additionally, green roofs on buildings play a significant role in stormwater management, absorbing up to 70% of rainfall. This reduces pressure on drainage systems. Finally, these spaces improve mental health, with residents living near them reporting lower stress levels. So, when planning cities, we must prioritize equitable access to green spaces.
