Arbor Day is a holiday dedicated to trees. It encourages individuals and groups alike to plant and care for trees. Originating in Nebraska City, Nebraska, the first American Arbor Day was held on April 10, 1872, and was spearheaded by Julius Sterling Morton. On this day, it is reported that approximately one million trees were planted in Nebraska.
Today, it is observed on the last Friday of April in Nebraska and many other U.S. states, although the date can vary in some states based on the best tree-planting times in their particular region. The observance of Arbor Day symbolizes both the great value trees provide such as clean air, habitat for wildlife, mitigating climate change by absorbing carbon dioxide, and the importance of sustainability and environmental stewardship in the United States.
Most Arbor Day celebrations involve tree planting activities and educational events that help individuals understand the importance of trees in their communities. Schools, businesses, and local governments often organize activities to encourage participation. Celebrations vary widely by state, with some states even declaring a state tree, predominantly in acknowledgement of Arbor Day's importance. It continues to be a holiday with a profound impact and significant importance among environmentalists.
