Arbor Day is a holiday dedicated to planting trees. It is celebrated on the last Friday of April in the United States, and on various other days in other countries. The first Arbor Day was celebrated in Nebraska in 1872, and it has since become a popular tradition all over the world.
Trees are important for many reasons. They provide us with oxygen, food, and shelter. They also help to clean the air and water, and they can even help to reduce crime. Planting trees is a great way to give back to your community and to help the environment.
