There is a global refugee crisis. The United Nations High Commissioner for Refugees (UNHCR) reported last year that there are at least 22.5 million people seeking asylum across state borders and tens of millions more have been internally displaced.
The numbers are growing as more people become displaced due to conflict and environmental disasters.
In response, from New York to Berlin to Sydney, leading political parties are building walls, figuratively and literally, instead of coming up with humane solutions.
