Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that adding more parks and tree-lined streets can reduce city temperatures by up to 4 degrees Celsius. However, the key is not just the number of trees but their placement. Shading buildings and pavements directly has the greatest cooling effect. Interestingly, the study also noted that green roofs on high-rise buildings were less effective for street-level cooling than ground-level parks. So, while vertical greening is popular, for maximum benefit, we should prioritize ground-level interventions in densely built areas.
❓ Según la conferencia, ¿cuál es la forma más efectiva de reducir las temperaturas urbanas?
A. Añadir más techos verdes en edificios de gran altura
B. Aumentar el número de árboles sin considerar su ubicación
C. Colocar árboles para dar sombra a edificios y aceras directamente.
D. Creando jardines verticales en las fachadas de los edificios
✅ 正确答案
