This is an international project that promotes planting trees in school surroundings. As such, the project is understood as an action that aims at making our planet a better place for a living, as well as a process that contributes to our spiritual growth. Since these two concepts (project as action and project as process) encompass two different spheres of living, i.e. material and emotional, we would try to intertwine the two as much as possible. This means the project would imply many different activities inside and outside of the classrooms. The project involves pre-primary and primary education (children aged from 4 to 15).
