Trees are not just beautiful to look at but also provide many benefits. Through the process of photosynthesis, trees absorb carbon dioxide and produce oxygen — act-ing as natural air filters. Trees improve biodiversity and provide habitat for wildlife. The roots of trees help prevent soil erosion. Trees can help prevent drought — they slow water runoff after heavy rainfalls and help to recharge underground aquifers. The shade of trees may help keep you and your home cooler. And in winter, trees can block the wind, helping to keep you warmer. Trees are also good for you. (Hospital patients recover more quickly when they have a view of trees.)The Latin word “arbor” means tree, and Arbor Day was created to encourage in-dividuals and groups to plant trees. Arbor Day began in Nebraska City, Neb., on April 10, 1872, with an estimated 1 million trees planted on that day. J. Sterling Morton cre-ated the first Arbor Day, and today, many countries observe a similar holiday accord-ing to the best time to plant trees in that country. In the U.S., the national holiday is celebrated on the last Friday in April.The Arbor Day Foundation, the world’s oldest tree-planting organization, began in 1972. Its mission is “to inspire people to plant, nurture and celebrate trees.” The foundation is supported by donations, by selling trees and merchandise, and by corporate sponsors. It encourages com-munities across the U.S. to become “Tree Cities.”Communities that want to become “Tree Cities” must meet the following guide-lines:• Establish a tree department or board.• Enact an official ordinance for
tree care.• Have a tree program with an
annual budget of at least $2 per capita.
• Embrace Arbor Day observances and proclamations.
