On April 22, the "Young Biologists Association" NGO in collaboration with "Mkhitar Sebastatsi" educational complex organised a tree planting in adjacent area of the school. The YBA members, together with schoolchildren from the educational complex, planted 45 trees on the 45th anniversary of Earth Day. An educational seminar on Earth Day's history and biodiversity of Armenia was also organised.

Earth Day was celebrated for the first time in 1970. The mission of Earth Day is to raise public awareness about environment, organise different environmental actions and to advocate for solutions for global environmental issues (e.g. climate change etc.). The quote of this year's Earth Day is "It's our turn to lead". Earth day is coordinated by Earth Day Network. Since 2010, the Young Biologists Association NGO is partner of the network in Armenia. The environmental activities of YBA are supported by the Rufford Foundation.
