National Tree Planting Day is observed in Kenya every April 21. This ecological observance encourages participation in tree planting events, where tree seedlings are distributed among schools for children to plant. The initiative aims to educate the youth about environmental protection and tree care. The celebration is rooted in the global tradition of Arbor Day, which originated in the USA in 1872 and spread to English-speaking countries before gaining traction in other regions. In Kenya, a common practice during this day includes planting coconut and palm trees along the southeast border, which is adjacent to the Indian Ocean. The event reflects the awareness of the environmental situation in the country and promotes community involvement in ecological preservation.
