答案
Trees can have a significant impact on our cities. They can make a city, as a whole, a bit less windy or a bit more windy, if that’s what you want. They can make it a bit cooler if it’s a hot summer day in an Australian city, or they can make it a bit more humid if it’s a dry inland city. On the local scale--that is, in particular areas within the city--trees can make the local area more shady, cooler, more humid and much less windy. In fact trees and planting of various kinds can be used to make city streets actually less dangerous in particular areas. How do trees do all that, you ask?
Well, the main difference between a tree and a building is a tree has got an internal mechanism to keep the temperature regulated. It evaporates water through its leaves and that means that the temperature of the leaves is never very far from our own body temperature. The temperature of a building surface on a hot sunny day can easily be twenty degrees more than our temperature. Trees, on the other hand, remain cooler than buildings because they sweat. This means that they can humidify the air and cool it--a property which can be exploited to improve the local climate.
Q: The professor describes the importance of trees in the city. Explain what impacts trees can have on our cities.
