The demands of the common good are dependent on the social conditions of each historical period and are strictly connected to respect for and the integral promotion of the person and his fundamental rights³⁴⁹ Cf. Catechism of the Catholic Church, 1907.. These demands concern above all the commitment to peace, the organization of the State's powers, a sound juridical system, the protection of the environment, and the provision of essential services to all, some of which are at the same time human rights: food, housing, work, education and access to culture, transportation, basic health care, the freedom of communication and expression, and the protection of religious freedom³⁵⁰ Cf. Second Vatican Ecumenical Council, Pastoral Constitution Gaudium et Spes, 26: AAS 58AAS — Acta Apostolicae Sedis (official gazette of the Holy See)Volume 58 (1966) at vatican.va — scanned PDF (1966), 1046-1047.. Nor must one forget the contribution that every nation is required in duty to make towards a true worldwide cooperation for the common good of the whole of humanity and for future generations also³⁵¹ Cf. John XXIII, Encyclical Letter Mater et Magistra: AAS 53AAS — Acta Apostolicae Sedis (official gazette of the Holy See)Volume 53 (1961) at vatican.va — scanned PDF (1961), 421..
