Pope Francis, in his encyclical Laudato Si invites us to become aware of this reality and to act responsibly for the safeguarding of the common house. Catholic schools must make a firm commitment to support the commitments of the international community by developing within each school, large or small, structuring educational projects for quality education (SDG4) and awareness of each student. that he can become an actor in the safeguarding of the common house.
