On June 5, 2021, 10 young adults and five volunteers from the Mexico City and Toluca Sri Sathya Sai Centers planted fifteen weeping willow trees near the Almoloya River and collected waste along the river area in Rancho de San Antonio, to commemorate the World Environment Day. The participants were taught to plant trees and learnt about the role of trees and water, in serving humanity selflessly. This activity had a positive impact on the participants, who also wrote down good wishes and tied them to each tree.
