Today in our environmental science lecture, we're discussing urban green spaces. Recent studies show that parks and community gardens can reduce city temperatures by up to five degrees Celsius. This cooling effect occurs because plants release moisture through transpiration, and shade from trees blocks solar radiation. However, the benefits aren't just physical. Access to green areas has been linked to lower stress levels and improved mental health among residents. Interestingly, the size of the green space matters less than its distribution. Even small pocket parks, if evenly spread across neighborhoods, can have a significant impact on both temperature regulation and community well-being. So, city planners should prioritize creating many small green spots rather than one large central park.
❓ Согласно лекции, каков ключевой вывод о городских зелёных зонах?
A. A. Крупные центральные парки более эффективны, чем небольшие.
B. B. Распределение зелёных зон важнее, чем их размер.
C. C. Зеленые зоны помогают снижать температуру только в крупных городах.
D. D. Растения выделяют влагу в основном ночью, чтобы охлаждать воздух.
✅ 正确答案
B. The distribution of green spaces is more important than their size.
