A/HRC/20/31 3. All peoples and individuals have a right to live in a world free of weapons of mass destruction. States shall urgently eliminate all weapons of mass destruction or of indiscriminate effect, including nuclear, chemical and biological weapons. The use of weapons that damage the environment, in particular radioactive weapons and weapons of mass destruction, is contrary to international humanitarian law, the right to a healthy environment and the right to peace. Such weapons are prohibited and must be urgently eliminated, and States that have utilized them have the obligation to restore the environment by repairing all damage caused. 4. States are invited to consider the creation and promotion of peace zones and of nuclear weapon-free zones. 5. All peoples and individuals have the right to have the resources freed by disarmament allocated to the economic, social and cultural development of peoples and to the fair redistribution of natural wealth, responding especially to the needs of the poorest countries and of groups in situations of vulnerability. Article 4. Peace education and training 1. All peoples and individuals have a right to a comprehensive peace and human rights education. Such education should be the basis of every educational system, generate social processes based on trust, solidarity and mutual respect, incorporate a gender perspective, facilitate the peaceful settlement of conflicts and lead to a new way of approaching human relationships within the framework of the Declaration and the Programme of Action on a Culture of Peace and dialogue among cultures. 2. Everyone has the right to demand and obtain the competences needed to participate in the creative and non-violent resolution of conflicts throughout their life. These competencies should be accessible through formal and informal education. Human rights and peace education is essential for the full development of the child, both as an individual and an active member of society. Education and socialization for peace is a condition sine qua non for unlearning war and building identities disentangled from violence. 3. Everyone has the right to have access to and receive information from diverse sources without censorship, in accordance with international human rights law, in order to be protected from manipulation in favour of warlike or aggressive objectives. War propaganda should be prohibited. 4. Everyone has the right to denounce any event that threatens or violates the right to peace, and to participate freely in peaceful political, social and cultural activities or initiatives for the defence and promotion of the right to peace, without interference by Governments or the private sector. 5. States undertake: (a) To increase educational efforts to remove hate messages, distortions, prejudice and negative bias from textbooks and other educational media, to prohibit the glorification of violence and its justification, and to ensure the basic knowledge and understanding of the world’s main cultures, civilizations and religions and to prevent xenophobia; (b) To update and revise educational and cultural policies to reflect a human rights-based approach, cultural diversity, intercultural dialogue and sustainable development; 5
