Today in our environmental science lecture, we're discussing the impact of urban development on local wildlife. One key point is that many cities have introduced green roofs, which are covered with vegetation. These roofs not only reduce heat absorption but also provide habitats for insects and birds. However, a recent study in London found that while green roofs attract more species than traditional flat roofs, they don't support the same diversity as natural ground-level habitats. The researchers suggest that to maximize biodiversity, we should connect green roofs with ground-level parks through 'green corridors'. Unfortunately, this is often overlooked in city planning due to cost and space constraints.
❓ ¿Qué reveló el reciente estudio en Londres sobre los techos verdes?
A. Sostienen más especies que los hábitats naturales a nivel del suelo.
B. Atraen menos especies que los techos planos tradicionales.
C. Tienen una biodiversidad mayor que los parques a nivel del suelo, pero menor que los hábitats naturales.
D. Son demasiado caros para que la mayoría de los planificadores urbanos los consideren.
✅ 正确答案
They have higher biodiversity than ground-level parks but lower than natural habitats.
