The current events that provoke mass migration, as shown by the war in Ukraine, or those involving millions of people driven by hunger or, as is also happening in more developed countries, driven by the search for working opportunities, well testify such a human behavior inherent in its own nature, a behavior that explicits the need and urgency of a universal recognition of a right which is still too often opposed today by a widespread cultural xenophobia.
Mobility, transition and structural collapse of barriers, these are perhaps some of the presuppositions that allow a contact, an exchange, an enrichment and an evolution of the human species.
