Today, in our environmental science lecture, we're discussing urban heat islands. You might think that planting more trees is the best solution, but recent studies show that reflective surfaces, like white roofs, can be more effective in reducing city temperatures. For example, in Los Angeles, a project to paint roofs white lowered local temperatures by up to 3 degrees Celsius. However, trees provide additional benefits such as improving air quality and supporting biodiversity. So, while white roofs offer immediate cooling, trees are a long-term investment. The key is to combine both strategies depending on the city's climate and infrastructure.
❓ 講師は、白い屋根と木々を比較して何と言っていますか？
A. 白い屋根は、あらゆる面において木々よりも効果的です。
B. 樹木は白い屋根よりも即効性のある冷却効果を提供します。
C. 白い屋根は効果が早いが、木々はさらなる環境上の利点をもたらす。
D. 木々は白い屋根よりも大気質への効果が低い。
✅ 正确答案
White roofs work faster but trees offer extra environmental benefits.
