Today in our environmental science lecture, we're discussing the impact of urban development on local ecosystems. One key example is the construction of a new highway near the city of Greenfield. Researchers found that the noise pollution from the highway reduced the breeding success of local bird species by nearly 40%. To mitigate this, they installed sound barriers along the road. Interestingly, the barriers also increased the diversity of plant life nearby because they altered wind patterns, which helped spread seeds. However, the study noted that the barriers were less effective for ground-nesting birds, as they still faced habitat fragmentation. So, while sound barriers are helpful, they are not a complete solution.
❓ Según la conferencia, ¿cuál fue el principal beneficio de instalar barreras acústicas a lo largo de la autopista?
A. A) Resolvieron completamente el problema de la fragmentación del hábitat para todas las especies de aves.
B. B) Aumentaron el éxito reproductivo de las especies de aves locales al reducir la contaminación acústica.
C. C) Mejoraron la diversidad vegetal al cambiar los patrones de viento que dispersaban las semillas.
D. D) Proporcionaron sitios de anidación para aves que anidan en el suelo.
✅ 正确答案
C) They improved plant diversity by changing wind patterns that spread seeds.
