Accord­ing to UN fig­ures, there were 19.5 mil­lion refugees world­wide at the end of 2014. The num­ber of peo­ple inter­nal­ly dis­placed by per­se­cu­tion, war or con­flict reached a record num­ber of near­ly 60 mil­lion peo­ple. Then we have all the num­bers who scram­ble from place to place because of their eco­nom­ic con­di­tions. We move to sur­vive, not to cause trou­ble or dis­com­fort for oth­er people.
