🎧 Listening Transcript

Today in our environmental science lecture, we'll discuss urban green spaces. Recent studies show that parks in cities can reduce local temperatures by up to 3 degrees Celsius during summer. This cooling effect comes from shade and water evaporation from trees. However, the size and distribution of parks matter. Small, scattered gardens have less impact than large connected areas. For example, a single large park of 10 hectares can cool surrounding streets for hundreds of meters, while many tiny plots only affect their immediate vicinity. Therefore, city planners should prioritize creating a few big parks over many small ones.
