Plant a Tree in Your Community

       Almost everyone loves trees, but did you know that trees can help people heal faster?

       It's true. According to the ISA (International Society of Arboriculture), hospital patients have been shown to recover faster when offered a view with trees. And while trees certainly benefit any landscapes -- whether lining residential streets, dotting urban areas, or in full glory in the forest -- they are actually important to our daily well-being.

       Trees improve the quality of the air around us by absorbing dust and other particulates (微粒), and release clean oxygen for you to breathe. If the health of people and the environment aren't high on your list of concerns, perhaps your wallet is: Trees make economic sense. A home surrounded by trees costs less to cool and heat. Neighborhoods with trees are often several degrees cooler than those in similar climates that don't have trees. In winter, trees can keep your house warmer by blocking high winds. Also, less water is needed in tree-shaded areas where the sun isn't constantly boating down on the earth below.

       Besides, trees can enhance privacy, block unpleasant views, and improve the value of your home. Unfortunately, these days, mass construction projects tend to wipe out all the trees in an area before creating new neighborhoods and buildings. That's why it's more important than ever to plant a tree in your community.

       Cheek out the NADF (National Arbor Day Foundation) online to find out more about planting a tree in your area or how to volunteer in an urban center. The Arbor Day Foundation can tell you how to plant a tree in someone's name as a gift, donate a tree in someone's honor, or memorialize a loved one by planting a tree.
