Cities Plant More Trees to Cool Hot Streets
Many cities plant trees to lower street heat and help people walk outside in summer.
In many big cities, summer heat is getting harder to handle. Dark roads and concrete buildings hold heat long after sunset. Local governments are planting more street trees because shade can lower the temperature on sidewalks. Trees also help catch dust and make walking routes feel safer. Young trees need regular water, so some communities organize weekend care teams. When streets feel cooler, people are more willing to walk, shop nearby, and spend time outdoors.

在许多大城市，夏天的炎热越来越难应付。深色道路和混凝土建筑在日落后仍会蓄热。地方政府种植更多行道树，因为树荫能降低人行道温度。树木也有助于吸附灰尘，让步行路线感觉更安全。小树需要定期浇水，因此一些社区组织周末养护队。街道更凉快时，人们更愿意步行、在附近购物并到户外活动。
