Today, in our environmental science lecture, we're discussing the impact of urban farming. A recent study in Chicago found that community gardens can reduce local temperatures by up to 2 degrees Celsius during summer heatwaves. This is because plants release moisture, which cools the air. However, the study also noted that the cooling effect is limited to a radius of about 50 meters from the garden. So, while city planners are keen on promoting rooftop gardens, they must consider the spatial distribution to maximize benefits. Interestingly, the study showed that gardens with a mix of trees and vegetables had a greater cooling impact than those with only vegetables.
❓ 講義によると、シカゴでの研究はコミュニティガーデンについて何を発見しましたか？
A. 彼らは全ての地域で気温を少なくとも摂氏3度下げます。
B. 彼らの冷却効果は、庭から約50メートルしか広がらない。
C. それらは夏よりも冬の方が効果的です。
D. 野菜だけの庭は、混植された庭よりも涼しさが保たれます。
✅ 正确答案
Their cooling effect extends only about 50 meters from the garden.
