Expressing gratitude toward the environment or trees shouldn't need a specific day. However, if there exists such a day, we must embrace it. April 28, Arbor day is observed annually to celebrate the role of trees in our lives. This day promotes tree planting and care.

The history of Arbor Day in the U.S. originates in Nebraska City. Among several pioneers moving into Nebraska in 1854 was a journalist named Julius Sterling Morton from Detroit. Nature loving Morton soon started spreading agricultural information and his enthusiasm for planting trees to a receptive audience in Nebraska's first newspaper, which he headed. Gradually, he encouraged everyone to set aside a specific day to plant trees. In 1872, the State Board of Agriculture accepted a resolution by Morton “to set aside one day to plant trees, both forest and fruit," according to National Arbor Day Foundation.
