Today in our environmental science lecture, we'll discuss urban green spaces. A recent study in Melbourne found that increasing tree coverage by just 10% can reduce local temperatures by up to 2 degrees Celsius during heatwaves. However, the study also noted that the benefits are not evenly distributed. Wealthier neighborhoods tend to have more mature trees, while poorer areas often lack sufficient green cover. To address this, the city council has proposed a new policy: planting at least 500 trees annually in underprivileged districts. But funding remains a challenge, so they are seeking partnerships with private companies.
❓ ¿Qué reveló el estudio en Melbourne sobre el efecto de aumentar la cobertura arbórea?
A. Puede reducir las temperaturas en 2 grados Fahrenheit durante las olas de calor.
B. Reduce las temperaturas locales hasta en 2 grados Celsius, pero los beneficios son desiguales entre los distintos barrios.
C. Solo ayuda a los barrios ricos porque tienen más árboles.
D. Requiere plantar 500 árboles cada año para ser efectivo.
✅ 正确答案
It reduces local temperatures by up to 2 degrees Celsius, but benefits are unequal across neighborhoods.
