Good morning, everyone. Today we're going to discuss urban planning, specifically the concept of 'green spaces' in cities. In a recent study, researchers found that adding small parks and rooftop gardens can significantly reduce the urban heat island effect. However, the key is not just the total area of green space, but its distribution. For example, a few large parks in the city center are less effective than many small ones spread across residential areas. This is because residents can access them easily, promoting more frequent use and better cooling. The study also highlighted that trees along streets contribute more to temperature reduction than isolated gardens. So, when planning future developments, we should prioritize connectivity and accessibility over sheer size.
❓ According to the lecture, what is the most important factor in making urban green spaces effective for cooling?
A. The total area of green space in the city.
B. The distribution and accessibility of green spaces.
C. The presence of rooftop gardens in commercial areas.
D. The number of large parks in the city center.
