The celebration of trees known as Arbor Day began in Nebraska in 1872. Julius Sterling Morton, a journalist, politician, agriculturist and member of the Nebraska state board of agriculture, proposed that a day be set aside and dedicated to the planting of trees, as well as educating the public about the importance of trees. The very first Arbor Day was celebrated on April 10, 1972 and in that single day over one million trees were planted. The state of Nebraska declared Arbor Day an annual legal holiday in 1885 and surrounding states were quick to declare Arbor Days of their own. In 1970 President Richard Nixon declared the last Friday in April to be National Arbor Day. Now Arbor Day is celebrated in around the world.Arbor-Day.net: Arbor Day
