Today in our environmental science lecture, we'll discuss urban green spaces. A recent study in Melbourne found that increasing tree coverage by just 10% can reduce local temperatures by up to 2 degrees Celsius during heatwaves. However, the study also noted that the benefits are not evenly distributed. Wealthier neighborhoods tend to have more mature trees, while poorer areas often lack sufficient green cover. To address this, the city council has proposed a new policy: planting at least 500 trees annually in underprivileged districts. But funding remains a challenge, so they are seeking partnerships with private companies.
❓ 墨尔本的研究揭示了增加树木覆盖率有何影响？
A. 在热浪期间，它能使气温降低2华氏度。
B. 它能将当地气温降低最多2摄氏度，但不同社区所获得的益处并不均衡。
C. 这只会帮助富裕社区，因为他们拥有更多的树木。
D. 每年需种植500棵树方能见效。
✅ 正确答案
It reduces local temperatures by up to 2 degrees Celsius, but benefits are unequal across neighborhoods.
