National Arbor Day is celebrated the last Friday in April, and its traditional observance is to plant a tree. When the first Arbor Day was celebrated on April 10, 1872, an estimated 1 million trees were planted. Imagine how big those 1 million trees are after 143 years!
Arbor Day’s celebration is rooted in the importance of trees to humanity. Like all plant life, trees take carbon dioxide from the atmosphere and produce the air we breathe. They give us shade, prevent erosion, provide the materials for the homes we live in, and are a source of fuel to keep us warm during the cold winter months.
