Planting a tree is a metaphor for life: the tree grows, roots in the ground, brings the foliage to the sky, changes shape and color during the seasons. Planting a tree is a symbolic and concrete action at the same time because it represents life that is renewed and that makes the world a more beautiful and livable place. Even a small tree can absorb CO2 and produce a significant amount of daily oxygen for life around the planet. A tree to grow must not only be planted, but also cared for and protected. Just like we do when we care about who we love.
