Almost everyone loves trees, but do you know that tree can help sick people recover faster? It's true. According to the International Society of Arboriculture (树木培植), hospital patients have been shown to recover faster when they are given a view with trees. Also, while trees certainly benefitany landscape, whether lining streets, decorating areas, or growing naturally in the forest, they areactually important in our daily lives. Trees improve the quality of the air around us by absorbing dust and other particles(颗粒物). Theirleaves also absorb harmful gases before we have a chance to take them in. They also protect us from thesun, rain, hail(冰雹), and snow, which can quickly damage unprotected homes. Even better, they often clean oxgiygen for us to breathe. Trees make economic sense. A home surrounded by trees costs less to cool and heat. Neighborhoods with trees are often several degrees cooler in summer than those in similar climates thatdon't have trees. In winter, trees can keep houses warmer by blocking strong winds. Also, less water is needed to water grass and gardens in tree-shaded areas where the sun isn't constantly shining. Besides that, trees can further improve privacy, block unpleasant views, and increase the value of your home. Unfortunately, these days, construction projects tend to wipe out all the trees in an area before creating new neighborhoods and buildings. That's more important than ever to plant a tree in your community. 1. The best title of the passage is about______.
