Arbor Day is observed in Argentina every August 29, with thousands of Argentinians participating in tree planting events organized at the national level. The celebration has its origins in 1900, when Domingo Faustino Sarmiento, the 7th President of Argentina, promoted the importance of trees and advocated for reafforestation to ensure the country's future well-being. The National Council of Education established Arbor Day on this date, and the modern celebration began in 1901. These annual events aim to combat deforestation and restore Argentina's diverse ecosystems, which are threatened by soil degradation. Through these activities, participants contribute to the ecological health of the nation by planting trees across various regions.
