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.
❓ Según la conferencia, ¿cuál es el hallazgo clave sobre los espacios verdes urbanos?
A. A. Los grandes parques centrales son más efectivos que los más pequeños.
B. B. La distribución de los espacios verdes es más importante que su tamaño.
C. C. Los espacios verdes solo ayudan a reducir las temperaturas en las grandes ciudades.
D. D. Las plantas liberan humedad principalmente durante la noche para enfriar el aire.
✅ 正确答案
B. The distribution of green spaces is more important than their size.
