Day of Trees is observed in Colombia on April 29 each year, where Colombians celebrate by planting trees. This holiday, akin to Arbor Day celebrated in various countries, highlights the importance of addressing environmental issues, particularly in Colombia. The tradition of Arbor Day dates back to the first documented arbor plantation festival in 1594 in the Spanish village of Mondoñedo. The modern observance of Arbor Day began in Spain in 1805 and has since spread globally, with over 50 countries participating. The Arbor Day Foundation, established in 1972, plays a significant role in promoting tree planting initiatives and combating deforestation worldwide.
